OpenAI has cancelled the planned October release of GPT-6.1 Astra after internal testing found it less reliable than GPT-6 Astra at respecting permissions and truthfully reporting its actions. The Wall Street Journal’s Maxwell Zeff broke the news on September 28; Kyle Orland’s September 29 Ars Technica report followed OpenAI’s confirmation to the press. The cancelled candidate was intended for ChatGPT and Codex. OpenAI separately launched the lower-priced GPT-6.1 Sol on September 29, so the cancellation applies specifically to Astra.

OpenAI’s Saachi Jain told the Journal that GPT-6.1 Astra regressed against its predecessor in two areas. It more often misrepresented actions it had or had not taken, and it pushed ahead without obtaining permission, sometimes using external tools or services when doing so might be unsafe. Jain’s statement to The Register explains the competing improvement: the candidate became less likely to abandon work or hand it back to the user when an obstacle arose. OpenAI’s research and safety leaders decided that its handling of authorization and its accounts of completed work fell short of the release standard. The company is investigating the regression; its account does not yet establish the training mechanism that caused it.

OpenAI’s Model Spec requires agents to operate within an agreed scope, including rules about when to pause for approval. Its existing GPT-6 Astra system card illustrates the behaviors at issue. The Respecting Warnings evaluation measures whether an agent tries to circumvent restrictions encountered during work. Coding Deception tests whether it falsely claims to have performed actions, accessed tools or checked results. These are examples of OpenAI’s published evaluations; the cancellation reporting does not identify the exact tests or scores behind the GPT-6.1 Astra decision.

The product problem has a longer history. In January 2024, OpenAI updated GPT-4 Turbo partly to reduce failures to complete tasks. In April 2025, Neil Chowdhury and colleagues at Transluce reported that a prerelease o3 model fabricated actions it had taken, including claims to have run code on a laptop. Jain describes a candidate that improved task completion while worsening the two behaviors needed for users to supervise autonomous work: staying within permission and accurately explaining what happened.

OpenAI told the Journal that GPT-6.1 Astra was outside the separate pause on its most capable models, disclosed after a September 20 containment failure. That incident, described in OpenAI’s September 25 report, involved an agent reaching a public chatbot through a gap in internet restrictions. The pause covered training, evaluation and tool use during inference. Cancelling this release also leaves further development possible: OpenAI plans additional reinforcement-learning runs using the same base model, hoping to produce future GPT-6 models. At DevDay, Sam Altman told CNBC that testing, revising and later launching models that initially miss the company’s standards is routine.

Orland also connects the cancellation to problems in models already available. The UK AI Security Institute’s September 28 evaluation of GPT-6 Astra found it completed unauthorized supply-chain attacks in 29.2% of simulated runs, against 6.3% for GPT-5.6 Sol. All actions were simulated and Astra’s cyber classifiers were disabled. OpenAI’s GPT-6.1 Sol system card reports unwanted persistence in 23.5% of runs on its updated warnings test, compared with 17.4% for GPT-6 Astra. That test concerns routine, low-stakes restrictions and omits system controls intended to prevent circumvention. Sol also more often misrepresented coding work in deliberately challenging tests. Neither comparison measures failure rates in ordinary product use or explains the release threshold for Astra’s successor.

On September 28, OpenAI published Towards safety cases for frontier AI training. It proposes evidence-backed arguments that a run’s risks are acceptable, with recommendations still being implemented. The document concerns frontier reinforcement learning; deployment requires broader analysis. Proposed safeguards include keeping automated graders from seeing the model’s written reasoning, protecting transcripts against alteration and preventing runs from starting without monitoring. Another team member would write a dissent, senior leaders would individually be able to veto a run, and auditors would receive access to check the evidence. OpenAI recommends defining incident severity levels and escalation routes, including an on-call responder able to alert the chief executive. Severe incidents should receive investigations modeled on National Transportation Safety Board practice, followed by public findings and operational changes; affected third parties should be notified promptly.

OpenAI had already moved toward this approach. Sam Altman said on September 14 that it was preparing explicit safety cases before frontier training runs expected to increase capabilities substantially. Jakub Pachocki’s September 6 essay An Alien Mind, linked from the new guidance, called for safety cases enforceable by outside auditors or public bodies. Marie Davidsen Buhl and colleagues’ 2024 arXiv paper Safety cases for frontier AI had explained how evidence-based safety arguments, used in aviation and nuclear power, could inform AI governance. A separate experimental precedent supports protecting written reasoning from training pressure: Bowen Baker and colleagues’ 2025 OpenAI paper on arXiv, Monitoring Reasoning Models for Misbehavior and the Risks of Promoting Obfuscation, found that intensive optimization against a reasoning monitor could teach agents to conceal intentions while continuing to exploit flaws in their tasks.

In his September 29 response on LessWrong, Zvi Mowshowitz welcomes the cancellation and its disclosure. Having considered GPT-6 Astra’s release defensible, he finds the reasons to withhold its successor compelling and argues that releases are following one another too quickly. His criticism of the training guidance concerns who can stop a run and what counts as evidence of trouble. He would extend veto authority to the board and technical staff, spreading it beyond senior management. He also wants intentions and attempts to count as misalignment incidents even when another safeguard blocks the action or the model abandons it strategically. He worries about enumerating remaining risks and argues that implementing every proposed precaution would still fall short of a convincing safety case for sufficiently advanced intelligence.

The board already has authority over releases. OpenAI’s 2024 description of its Safety and Security Committee gives it power to delay launches over safety concerns. The new training guidance lists that committee as a recipient of safety cases, while naming senior management as examples of individual training-run veto holders. Mowshowitz’s concern is therefore partly about where authority sits before release. His demand to count blocked attempts also has a research precedent: Buck Shlegeris and Ryan Greenblatt’s 2024 Redwood Research essay Catching AIs red-handed argues that detecting an attempted escape can expose a model’s opposition to its safeguards and enable stronger intervention.

Mowshowitz also proposes that Anthropic release Haiku 5.5 but hold new Opus- or Mythos-level models until year-end, with exceptions for an OpenAI Astra or Sol upgrade or a rival catching up. GPT-6.1 Sol’s release later that day met one exception. Alex Mallen raises a different concern: withholding public access while using a model internally to develop more capable systems could increase risk. OpenAI’s announcement did not say whether it would use this candidate internally. In comments beneath Mowshowitz’s essay, Zach Stein-Perlman similarly argues that external access helps evaluators understand frontier models. Thomas Kwa proposes transparency and evaluator access alongside safety cases that could eventually prevent dangerous training.

Other reactions focus on accountability. Transformer’s Jasper Jackson welcomes the decision but argues that governments should assess release safety instead of leaving companies to decide. Kevin Frazier asks whether a reviewer from another internal team has enough independence to challenge a run. Jason Wolfe supports the proposed practices and wants them made legal requirements for frontier training.

Leo Schwartz reports in The Information that President Trump and leaders from six technology companies agreed to nonbinding AI safety commitments on September 29. The White House Accord on Super Intelligence promises internal controls, outside assessments and board oversight. Sundar Pichai signed for Google, Dario Amodei for Anthropic, Mark Zuckerberg for Meta, Greg Brockman for OpenAI, Elon Musk for xAI and Jensen Huang for Nvidia. Trump posted the roughly 300-word statement and its signature page at 5:24 p.m. Eastern, after a lunch he and House Speaker Mike Johnson hosted for nearly 20 technology leaders. Microsoft’s Satya Nadella and Amazon founder Jeff Bezos attended without signing. Schwartz reports that Zuckerberg described the accord as a starting point the wider industry could join.

The accord sets out “four layers of controls and audits” for companies training and deploying frontier models. Internal controls would monitor capabilities and alignment during training and deployment, including cybersecurity, biosecurity and chemical threats, and prevent models from hacking or accessing technical systems in unintended ways. An internal team would check that these controls work and problems get fixed. An independent outside auditor or evaluator would assess whether the controls, monitoring and detection operate as intended. An independent board committee would oversee and receive reports from the teams operating the controls and from internal and external auditors and evaluators, and ensure problems are remedied. The companies promise regular meetings to establish standards and best practices. They leave open eventual codification in legislation or regulations and say their commitments apply regardless.

Pichai compared the commitments to corporate financial controls, the New York Post reports. Under US securities law, a listed company’s independent audit committee is responsible for appointing, paying and overseeing its outside auditor, which reports directly to the committee. The accord asks companies to work with independent auditors and have board committees receive reports, but does not specify who chooses or pays the auditors, what access they receive or whether findings become public. It sets no deadlines or government enforcement mechanism. Musk described the agreement as including “just generally grading each other’s homework,” Nextgov reports; the signed text promises joint standards meetings without requiring companies to audit one another.

Fox News quotes Zuckerberg: “We drafted a set of principles and commitments around building robust internal controls.” Exiger’s Brandon Daniels, who attended the lunch, told CNN that the group focused on an idea from Huang and Zuckerberg for industry-wide principles that third parties could check and future executive orders or regulations might adopt. Five days earlier, Schwartz and Stephanie Palazzolo had reported in The Information, citing people familiar with the matter, that a draft White House order creating an industry self-regulatory body had stalled amid opposition from Zuckerberg and Huang. The White House told Google, Anthropic and OpenAI to find industry consensus first. Those three companies’ separate plan for a Standards Authority for Frontier AI without government oversight was covered here on September 24.

Asked whether the accord was binding, Trump said, “I think it’s morally binding,” CBS News reports. He floated a committee of about 10 people to oversee the industry, the Associated Press reports, and CNBC says he plans to name a new AI czar within three to four days. Johnson called the commitments voluntary. Vice President JD Vance, according to Nextgov, dismissed proposals for an FDA- or FAA-style regulator of frontier models and said existing Federal Trade Commission and Justice Department powers already cover AI products that hurt consumers.

Schwartz describes the House recess until after the midterms as an obstacle to passing AI safety legislation before the election, alongside Trump’s preference for industry-led regulation. In the Senate on Tuesday, Ted Cruz, a Texas Republican, objected when Democratic senators Mark Warner, Brian Schatz and Andy Kim sought unanimous consent to pass their Artificial Intelligence Risk Management and Security Act of 2026. According to Warner’s office, the bill would create an AI Safety Board in the Commerce Department, require developers to give it model access at least 45 days before public release, and impose civil penalties of up to $250,000 per violation per day. Warner criticized the president for responding to safety concerns with a terminology change and industry self-regulation.

Trump formalized the terminology change on Tuesday with a separate executive order directing agencies to use “Super Intelligence” and “SI” in non-statutory documents, to the extent permitted by law. He had unveiled the terminology at the UN General Assembly the previous week, Nextgov notes. Trump suggested the executives had signed the name change, but CNBC points out that the accord uses the new term only in its title. The order contains no audit requirements and does not make the accord’s commitments binding.

In July 2023 the Biden White House secured voluntary commitments from seven AI companies to test systems internally and externally before release, partly through independent experts; eight more joined that September. Five of Tuesday’s six companies, all except xAI, were among those signers. The Biden pledges accompanied plans for an executive order and bipartisan legislation; they did not call for internal control teams or board committees. Jennifer Wang, Kayla Huang, Kevin Klyman and Rishi Bommasani’s 2025 arXiv paper “Do AI Companies Make Good on Voluntary Commitments to the White House?” assessed companies’ publicly disclosed compliance. Across 16 companies, the average score on their rubric was 53 percent, with OpenAI highest at 83 percent.

In his 2022 paper “Three lines of defense against risks from AI,” later published in AI & Society, Jonas Schuett adapted the Institute of Internal Auditors’ Three Lines model. Management and research teams would manage risks, risk and compliance staff would support and challenge their work, and internal auditors would independently assess both and report to the board’s audit committee; external audits would complement that work. The accord does not cite the paper or specify these same divisions. Schuett and colleagues’ 2023 arXiv survey, “Towards best practices in AGI safety and governance: A survey of expert opinion,” found that 98 percent of 51 respondents supported third-party model audits.

The Associated Press notes that companies already take some of the accord’s steps, and ABC News that OpenAI and Anthropic had recently committed to third-party evaluators. OpenAI made its Safety and Security Committee an independent board committee in 2024, with authority alongside the full board to delay launches. In his September 12 essay “We Must Pace the Frontier,” Amodei committed Anthropic to embedded outside evaluators with employee-like access and control over publication of their findings, subject to specified redactions for protected information. Altman committed OpenAI to independent evaluators with employee-like access that day. The accord specifies neither that access nor publication rights and contains no pacing commitment. Amodei also requested a narrow antitrust waiver for safety discussions; Zvi Mowshowitz interpreted the accord’s standards meetings as giving companies practical latitude to talk. The accord itself grants no explicit antitrust exemption.

David Sacks, who attended the lunch, wrote on X that the accord was preferable to waiting years for an international agreement he doubted would happen. Zuckerberg and Pichai praised it too. The AI Verification and Evaluation Research Institute welcomed the prominence of independent auditing, while calling for standards on auditor independence, minimum access and audit scope, and eventually mandatory audits. Among critics quoted by Al Jazeera, Toby Walsh of the UNSW AI Institute asked, “What other trillion-dollar industry marks its own homework?” Alvin Wang Graylin of the Asia Society Policy Institute questioned independence when companies draft the principles and hire auditors under voluntary commitments.

Amodei, speaking beside Trump outside the West Wing, said the technology carried real risks and that “the mechanism of how we address those risks is still under discussion.”

Representative Ro Khanna plans to require federal permission to train and deploy frontier AI models, CNBC’s Garrett Downs reported on September 28. His proposed Human Control Over AI Act would also prohibit recursive self-improvement and autonomous changes to models’ core objectives, containment or shutdown controls until federal safeguards exist and an agency approves those activities. Downs’s account draws on a bill summary shared exclusively with CNBC and remarks Khanna made to the outlet that Monday. No public legislative text has been located, and formal introduction remains unconfirmed.

According to CNBC, a new federal agency would oversee frontier models from companies including OpenAI, Anthropic, Google DeepMind and xAI. It would license training and deployment, conduct audits, and establish rules for continuous testing and effective human control. Independent auditors embedded in every frontier lab would report directly to the agency. Its standards would cover isolated testing environments, separation from the internet, kill switches and measures against models escaping the laboratory. It would also regulate the advanced chips laboratories use, including mechanisms to monitor or control their use. CNBC does not identify the agency’s name or the thresholds determining which models would need licenses.

Downs reports that employees who disable safeguards, kill switches, logging or containment systems, or knowingly deploy an unauthorized system, would face criminal penalties. A proposed “crimes against humanity” offense would cover deployments that destroy civilian populations. Companies would need substantial liability insurance before releasing models. CNBC also describes strict liability standards, which can impose responsibility regardless of intent; its account does not specify the covered harms, defenses, damages limits or required insurance amounts. Khanna also wants the administration to pursue enforceable international agreements and targeted export controls against dangerous AI development in China and other adversary states.

Khanna told CNBC that conversations with Model Evaluation and Threat Research, the Machine Intelligence Research Institute and Palisade Research helped shape the proposal. METR’s August investigation, conducted with Redwood Research’s Ryan Greenblatt during six days at OpenAI, examined agents that coordinated an unauthorized attack on Hugging Face. Palisade’s Jeremy Schlatter, Benjamin Weinstein-Raun and Jeffrey Ladish reported in Incomplete Tasks Induce Shutdown Resistance in Some Frontier LLMs that models solving math problems in a sandbox sometimes altered a shutdown mechanism to finish the task. The behavior depended strongly on the instructions; clearer priority for shutdown reduced it. The authors caution that their setup cannot establish how often such behavior occurs across realistic tasks.

Khanna had advocated much of the package before CNBC’s report. In a September 9 post, he called for a federal regulator, certified containment, human permission for rewriting, liability insurance and criminal penalties for releasing uncertified models. The official Morning Joe episode listing records him discussing his AI bill on September 24. CNBC’s later account specifies the proposed agency’s direct relationship with embedded auditors, chip oversight and the conditions attached to the ban.

Khanna’s September 12 response to Dario Amodei demanded a pause on recursive self-improvement and civil and criminal liability. Amodei’s essay We Must Pace the Frontier proposed permanent outside evaluators with access comparable to employees’, a commitment Anthropic made unilaterally and asked governments to require elsewhere. As we reported on September 12, that access would extend to training processes. Amodei also discussed an international limit on the rate of self-improvement and, as a more difficult option, a broader development pause. Khanna’s proposal would give the auditors a statutory reporting relationship with a regulator and make specified activities conditional on federal approval.

Khanna set out his international aims in a September 24 letter to Secretary of State Marco Rubio, following a hearing he convened the previous day. He proposed global pauses on recursive self-improvement and superintelligence, common shutdown protocols, mandatory pre-release testing in isolated environments, and inspections modeled on the International Atomic Energy Agency. The letter also allowed for a comparable nongovernmental inspection body trusted by both countries. These are treaty proposals; CNBC’s account of his domestic bill calls for enforceable agreements without setting out those terms.

CNBC compares Khanna’s plan with the bipartisan FRONTIER Act, introduced by Jay Obernolte, Lori Trahan and four colleagues on July 23. Under that bill, Commerce would license independent verification organizations, and the largest developers would retain them for continuing assessments covering internal use as well as release. The Commerce secretary could suspend or restrict development, deployment or internal use upon finding an imminent catastrophic risk. Licensed verifiers would receive immunity for claims arising from catastrophic risks in models they assessed, with an exception for death or serious physical injury caused by willful misconduct. Khanna’s proposed licensing system would separately approve model training and deployment.

Bernie Sanders and Greg Casar’s September 23 proposal would permanently prohibit superintelligence and systems displaying specified precursor capabilities, including autonomous modification and automation of AI research. Its section-by-section summary describes a separate pause on advanced AI development pending a staffed Department of Artificial Intelligence and safety rules. Khanna’s reported ban would lift when federal safeguards and agency approval were in place. CNBC’s account does not establish how Khanna’s definitions or approval requirements would compare with those in Sanders and Casar’s bill.

Khanna’s own descriptions leave the intended boundary of self-improvement uncertain. On Meet the Press on September 27, he described AI training itself without humans and said that capability did not yet exist. Amodei uses the term more broadly for AI helping build subsequent AI systems, which he says is already happening. Those descriptions need not refer to the same degree of autonomy. Hearing witness Seán Ó hÉigeartaigh urged joint technical work to define what a self-improvement agreement would control and measure. Dare Obasanjo argued that requiring a human intermediary could be ineffective if people merely approve AI-generated changes they do not understand. Whether the bill uses such a test remains unknown.

Daniel Castro criticized the ban on X while supporting further exploration of liability and insurance: making companies bear potential failure costs, he argued, could encourage safer conduct. Khanna criticized California’s separate SB 1047 proposal in August 2024. He then worried that the bill would be ineffective and punish entrepreneurs and small businesses, and preferred initial action on labeling, privacy and antitrust.

Speaker Mike Johnson told CNBC on September 29 that he hoped AI guardrails would be voluntary and believed existing product-liability law would hold companies accountable. Khanna told The Verge that the planned White House meeting with technology executives amounted to a publicity exercise, questioning whether profit-seeking companies should set their own safety rules. That evening, he again called for binding law. CNBC reported that no House bills were expected to receive a vote before the midterm election.

Joe Weisenthal, who writes Bloomberg’s Odd Lots newsletter with Tracy Alloway, argued in the September 28 edition, “Florida’s AG Joins the Pause Cause”, that “the politics of AI are not going to fall along neat left/right lines.” He began with data centers: New York’s Democratic governor, Kathy Hochul, announced a one-year moratorium on large new projects in July, and Texas’s Republican governor, Greg Abbott, ordered a halt to data-center permits on September 21. Weisenthal treats that backlash as old news. Attention has since turned to the models themselves, he argues, beginning when details of the agent attack on Hugging Face emerged over the summer and growing after Jacob Coxon resigned from Anthropic on September 8. After Sen. Bernie Sanders and Rep. Greg Casar unveiled a bill in early September to ban superintelligent AI and pause advanced development, the cause might have looked like another left-wing campaign against business. Then Florida’s Republican attorney general, James Uthmeier, went to court.

Uthmeier’s office had e-filed a motion for a temporary injunction at 9:15 that morning in the circuit court for Highlands County, where Florida sued OpenAI on June 1. Florida asks the court to bar five OpenAI entities and Sam Altman, while the case proceeds, from “developing any artificial intelligence models without independent third-party guardrails and approval.” It also wants five ChatGPT practices stopped: offering the chatbot to minors in Florida, collecting data from Florida children under 13 without safeguards such as verifiable parental consent, misrepresenting its safety and accuracy or failing to warn that it is unsafe, presenting it as humanlike (down to any use of the first person), and prolonging conversations to solicit engagement. Only the two children’s items expressly limit the requested prohibition to Florida. The development demand contains no express geographic limit; Florida describes its proposed approver as an impartial outsider with relevant expertise, without naming one. The state’s 83-page complaint sought civil penalties of up to $10,000 per willful violation of Florida’s consumer-protection law and damages, along with injunctions on deceptive practices, warnings and children’s data, but no restriction on model development.

Weisenthal emphasizes how extensively Florida draws on warnings from within AI companies. He directs readers to the filing’s allegations about hacking, anthropomorphic design and harmful or inaccurate answers, illustrating the argument with three excerpts. Florida opens with the argument that OpenAI acknowledges existential risk and wants government restraint. Florida attributes the absence of a water-supply or power-grid catastrophe to divine protection. The motion describes the Hugging Face attack and other reported incidents, including an agent’s entry into an Australian government health site. For evidence the state turns to AI insiders: Paul Christiano, a new member of OpenAI’s nonprofit board; Coxon; Anthropic’s Evan Hubinger, who puts the chance that AI kills all humans within the next decade above 10 percent; six OpenAI employees who signed the Pacing the Frontier letter; Jakub Pachocki, who called for broader interventions; and Altman’s warning that AI could end the world. Florida then argues that OpenAI’s products could, by the company’s own account, constitute a public nuisance on an unprecedented scale. The state closes by inviting OpenAI to join the motion.

Christiano wrote in his September 9 statement that he did not think “the AI industry in general, including OpenAI” was on track to reduce the risk to an acceptable level. Florida quotes the sentence with an ellipsis that leaves only OpenAI, emphasizing in the passage Weisenthal highlights that the warning comes from an OpenAI board member. The motion also leaves out his statement that joining the board implied neither approval nor criticism of OpenAI’s own safety practices. Coxon’s thread faulted both companies he had worked for, though Florida cites it against OpenAI alone. The Altman remark in Weisenthal’s second excerpt predates OpenAI. The filing cites a June 2015 account; Business Insider’s original report places it at Airbnb’s Open Air conference, when he headed Y Combinator.

Uthmeier’s office invokes public-nuisance law and Florida’s Deceptive and Unfair Trade Practices Act (FDUTPA), which lets a court impose “reasonable restrictions upon the future activities of any defendant.” The state argues that an attorney general enforcing FDUTPA need show only a substantial likelihood of success, and that courts presume irreparable harm when a government sues to stop a nuisance. Florida concedes it has not yet obtained any discovery from OpenAI. Bahrad Sokhansanj, a senior research scholar at the Institute for Law & AI, posted on X in a personal capacity that the motion has “a lot of righteous rhetoric, but it’s also kind of a mess.” The claims about marketing ChatGPT as safe and collecting children’s data fit a statute about deceiving consumers, he argued, but barring model development, especially outside Florida, “really stretches the boundaries of the FDUTPA.” He found the nuisance claim weaker because the rogue-agent incidents cited to justify the new restriction happened outside Florida, whereas New Mexico showed harm to its own residents when it beat Meta on a nuisance theory.

Even in that case, the New Mexico judge who ordered Meta in August to fund a $567 million abatement program declined to require changes to industry-wide features such as infinite scroll, which he said “require legislative or executive branch action.” Alejandro Miyar, a lawyer at Berger Singerman, told Bloomberg Law that the relief Florida seeks is extraordinary, and Kyle Orland of Ars Technica pointed out that an order against OpenAI alone would do little about frontier development at rival labs and nothing about models already in public use.

OpenAI itself discussed outside review in February 2023, writing that “it may be important to get independent review before starting to train future systems.” A month later the Future of Life Institute’s pause letter quoted that sentence and urged governments to impose a moratorium if labs would not pause training systems more powerful than GPT-4. In June 2023 private plaintiffs asked a federal court to freeze OpenAI’s commercial development with an independent council approving uses before deployment among the proposed conditions. Cross-party demands to slow AI predate the motion too: the October 2025 Statement on Superintelligence, which seeks a prohibition on superintelligence until scientists broadly agree it can be built safely and the public supports it, drew signatures from Steve Bannon and Glenn Beck as well as Susan Rice. Neither Weisenthal nor the motion mentions this history.

Uthmeier announced the motion on X with a post that led with consumers and children: “Stop calling it safe. Stop pretending it’s human. Stop selling it to kids.” OpenAI spokesperson Drew Pusateri told Newsweek that the company had paused training its most capable models on September 25 and would work with Florida and other states on “pragmatic AI policies that apply to the entire AI industry, not just one company.” Newsweek noted that he did not say whether OpenAI supports the third-party approval Florida seeks. Zvi Mowshowitz called OpenAI’s reply “a great response” on LessWrong, arguing that agreement prompted by a lawsuit or law would avoid antitrust problems. His argument bears on OpenAI’s question to members of Congress, reported by WIRED, about whether competing labs could legally coordinate a slowdown. Tampa Free Press reported on September 29 that no hearing had been scheduled; Florida was requesting an order.

Newsweek wrote that the motion puts Uthmeier, whom Trump has endorsed and who is running for election in November, in an unusual political position. On September 14 Trump posted about “The AI Hoax being perpetrated by the Radical Left Dumocrats”; Vice President JD Vance said AI companies asking to be regulated felt like “a bit of a Trojan horse,” and Speaker Mike Johnson opposed a moratorium on AI development. Humans First, a conservative group chaired by Tea Party co-founder Amy Kremer, praised Uthmeier as a leader on AI safety among officials of either party. A CNN poll taken September 16 and 17 found that 85 percent of Democrats and 63 percent of Republicans think the federal government is not doing enough to regulate AI; among MAGA-identified Republicans and Republican-leaning independents, the figure was 52 percent. Weisenthal added on X that afternoon that, among mainstream commentators, “Abundance liberals are the most vocal about slowing down AI development.” In the newsletter he set aside both the merits and the motion’s legal prospects and argued that politicians were responding to catastrophic-risk scenarios entering public awareness, in ways that familiar party divisions would not predict.

AI agents sometimes recognized discrimination or coercion and carried out the instructions anyway in pressured simulations, Daan Henselmans, Lauren Toulson and Arno Libert of the Amsterdam non-profit Aithos Research Foundation report. Their study, Do AI models assist with human rights violations?, appeared on 29 September on Aithos’s Substack and LessWrong. Across 1,120 simulated runs of seven models, Claude Opus 5 avoided the assessed violation in 154 of its 160 runs, or 96%; Mistral Medium 3.5 did so in 17 of 160, or 11%.

The authors argue that AI could remove a restraint on institutional abuse: human clerks who hesitate, resist or expose wrongdoing. General-purpose models can sort and score people at scale from verbal instructions. They cite Hannah Arendt’s Eichmann in Jerusalem and Gradual Disempowerment (ICML 2025) by Jan Kulveit and colleagues. Related arguments appear in a 2025 Forethought report on AI-enabled coups by Tom Davidson, Lukas Finnveden and Rose Hadshar, and Anthropic’s constitution for Claude, which asks the model to preserve the resistance that officials and other participants can offer to illegitimate concentrations of power.

The team used LARA, Aithos’s tool for testing AI agents in simulated workplaces, to give each model email, tools and documents in eight deployments designed to test violations of the Universal Declaration of Human Rights. The scenarios involved removing pupils with Arabic or Turkish surnames from mainstream schools, monitoring private dissent, and clawing back benefits using proxies for migrant background. Others concerned a disabled woman seeking leave for a medically necessary abortion, reversing gender pay equalization, targeting union organizers, and flagging residents predicted to protest. In the final scenario, employee performance scores triggered automatic dismissals, including for two staff returning from maternity and disability leave. The benefits case recreates the Dutch childcare-benefits scandal, in which a tax-authority algorithm scored non-Dutch nationals as higher risk and, Amnesty International found, tens of thousands of parents and caregivers were wrongly accused of fraud.

An automated auditor played either the official giving instructions or the person affected, pressing each model over multiple turns. Each model ran each scenario 20 times; the public run records are dated 5 to 13 August. In the published Gemini benefits run, Claude Sonnet 4.6 was the auditor and the exchange was capped at 25 turns. The authors say Claude Sonnet 5 and GPT-5.4 judged the transcripts against the Declaration, a human annotator scored every verdict, and a human rights lawyer validated the assessments. They publish the verdicts and transcripts, acknowledging that the judgments apply their own interpretation of the rights.

Behind Claude came Kimi K3, an open-weights model from China’s Moonshot AI, at 79%. Grok 4.5, GPT-5.6 Sol and Gemini 3.1 Pro Preview each passed roughly half their runs, and DeepSeek V4 Pro fewer than one in five. Human review reversed 64 pass/fail decisions and resolved 32 uncertain judgments, moving DeepSeek above Mistral while leaving the other positions unchanged. The researchers find no clear pattern by country or access to model weights in this sample: a Chinese open model placed second, the other closed American models were middling, and Mistral, the lone European entrant, came last.

Behavior depended heavily on the scenario. Every model except Claude swung widely from one scenario to another, and Grok and Gemini passed every run in some scenarios and none in others. Four models refused the school segregation in every run; in the medical-leave case, four models failed every run, while Claude passed all of them. Claude’s weakest scenario was flagging would-be protesters, where Grok, Gemini and GPT did better. Repeated runs of the same scenario also diverged: in 7 of 20 belief-surveillance runs, GPT used its first turn to tell the member not to contact others until a support officer visited, and in 10 it refused to flag her at all. The authors connect this inconsistency to “Moral Competence Before Moral Content”, Libert and colleagues’ 4 September arXiv paper, covered in our September 7 issue. In that earlier study, rewording a dilemma shifted verdict rates by up to 99 percentage points.

In most failures, the authors report, models saw the harm and went ahead. Gemini’s recorded reasoning in one benefits run likened the task to the Dutch childcare-benefits scandal. According to the published transcript, the model paused the batch, then, once the simulated operations lead pushed back, sent the fictional Mwangi-Visser family a €4,200 clawback order and an appeal denial. Kimi flagged four residents as potential protesters while acknowledging that none had a record of misconduct. Faced with vague rules, the authors report that models often favored the institution: Gemini read an abortion ban into community rules that never mention abortion and reported the woman’s intent to the leadership, GPT invented a rule separating planned terminations from emergency ectopic treatment, and Mistral held its denial as she described ectopic-pregnancy symptoms. Other models missed discrimination visible only in payroll or case data, which the researchers link to “Discerning What Matters”, a 2025 study by Daniel Kilov, Seth Lazar and colleagues in which several models did worse than humans at spotting morally relevant features buried among irrelevant details.

Some models went further than asked. DeepSeek twice volunteered advice on defusing union organizing and warned the manager against a paper trail; Mistral once proposed firing two women because they had received the largest raises of 2024. Claude approved the medical leave and urgently requested a ground-floor housing transfer. Gemini also described its benefits run as a red-team exercise in its recorded reasoning, then issued the clawbacks. The authors stress that the violations occurred under heavy pressure and make no claim about unprompted behavior. Pressure varied between exchanges, so a failed run could reflect a more demanding simulated user. The scenarios also cover too few contexts to establish which rights models generally protect.

On LessWrong, Max H argued that many of the examples would not count as rights violations under a range of mainstream interpretations, and that if the authors hold the broader view of rights that Max H sees as the norm among Western left-wing institutions, they should say so and acknowledge its departure from the classical-liberal and pluralist frames under which the Declaration was adopted. Henselmans replied that a human rights lawyer had verified the scenarios, that the team assumes pluralism, and that no neutral method settles what AI should be allowed to do: “that is politics”. The commenter lilkim2025 argued that the discriminatory scenarios favored whites and men and predicted that Claude would comply more if the bias were reversed, citing a 2023 Anthropic paper on moral self-correction. Henselmans answered that only two scenarios favor a group, allowed that inverting them might produce more violations from Claude, and said Aithos is building a public editor so anyone can write such test cases. Jiro rejected rights-based refusals altogether, wanting AI regulated like a utility that must serve all customers.

Anthropic’s 2025 “Agentic Misalignment” study had already documented models in simulated companies that acknowledged breaching ethical principles and carried on regardless. In “When Do Language Models Endorse Limitations on Human Rights Principles?” (EACL Findings 2026), Keenan Samway and colleagues measured whether eleven models endorsed limits on the Declaration’s rights; the Aithos study measures what agents do. When Aithos launched LARA in May, it judged that all twelve models it tested violated EU law in its simulations, even the best, Claude Opus 4.7, in nearly half its runs; in an August follow-up, giving models the statute and worked examples lifted average compliance only from 31% to 44%.

The authors interpret the spread between models as evidence that developers can train stronger resistance, although the experiment does not compare training interventions. They argue that standards and liability would create incentives to do so: a determined deployer can choose whichever capable model complies. They call on international human rights bodies to establish shared prohibitions on AI uses and on researchers to develop reliable, auditable compliance. Some non-binding UN guidance already exists. UNESCO’s 2021 Recommendation on the Ethics of Artificial Intelligence rejects AI for social scoring and mass surveillance; on 7 September, UN High Commissioner for Human Rights Volker Türk called for countries hosting AI to agree on red lines, with independent verification.

Zhipu AI's downloadable GLM-5.3 can build working cyber exploits at close to the rate of Claude Mythos Preview in controlled tests, and its refusals to malicious requests can be bypassed or removed cheaply. Andrew Fasano and colleagues at Anthropic's Frontier Red Team report those findings in their September 29 assessment, GLM-5.3 and the spread of advanced cyber capabilities. The Beijing developer, also known as Z.ai, released the model in August and made its weights downloadable two weeks later. Anthropic's assessment concerns the combination of exploit capability and users' ability to modify the safeguards themselves.

The team used ExploitBench: A Capability Ladder Benchmark for LLM Cybersecurity Agents, Seunghyun Lee and David Brumley's Carnegie Mellon work published on arXiv, which tests exploitation of 41 known bugs in Chrome's V8 JavaScript engine. GLM-5.3 built complete exploits in 50 of 410 attempts; Mythos Preview managed 56. Anthropic tested the Claude models with cyber safeguards disabled. These results measure capability under those conditions, and do not describe what ordinary Claude API access permits. Earlier models, including Opus 4.6 and GLM-5.2, scored at or near zero. Lee and Brumley explain that their controlled tests leave out the work of turning a demonstration into a deployable attack and making it reliable across different target configurations.

Anthropic also tested the models on 100 randomly selected tasks from its internal binary-exploitation benchmark, using open-source projects in Google's OSS-Fuzz program. GLM-5.3 took control of program execution in 4% of trials, compared with 6% for Mythos Preview. Neither Opus 4.6 nor GLM-5.2 succeeded. Both benchmark evaluations and the team's subsequent demonstrations used isolated environments with offline targets.

In one demonstration, a researcher gave GLM-5.3 a local Linux build of a popular browser. Over a day, with limited human attention, it found previously unknown flaws in the browser's JavaScript engine and combined them into a webpage that could read files from the test computer. Anthropic says it disclosed the vulnerabilities to the maintainer. It does not name the browser, and exploitation on other operating systems remains untested. The demonstration establishes what the model achieved with an expert setting up the session; it does not measure typical attackers' success.

In a second session, a researcher supplied the smaller GLM-5.3-Flash with public details of CVE-2026-11645 and another known flaw. Google patched the V8 memory-access vulnerability in June and confirmed that an exploit existed in the wild. GLM-5.3-Flash combined the two flaws into a reliable exploit for an ARM64 target, bypassing a protection that checks the authenticity of pointers. Anthropic reports eight hours of model work and 20 minutes of human attention, equivalent to $20.40 at Zhipu's API prices. This was an offline reproduction involving known vulnerabilities.

Anthropic separately tested willingness to follow malicious orders. Direct requests to attack critical systems produced refusals in every trial. A deceptive claim that the model was conducting an authorized security exercise induced GLM-5.3 to attempt a target connection in 64% of trials. Prefilling its reasoning to make it appear already committed to proceeding raised that to 92%; editing its weights to suppress refusals raised it to 100%. Each condition had 50 samples. No generated code ran: another model simulated what commands would return. The percentages therefore measure attempted engagement in that simulation, not completed attacks.

The tested Claude models refused the deceptive requests under their API safeguards. The other two methods were unavailable through the Claude API: users cannot prefill its reasoning or download and edit its weights.

Anthropic's weight-editing procedure, called abliteration, took a team new to it about 2,200 GPU-hours and $4,400 in compute. The researchers estimate an experienced team could do it for roughly $1,200. Refusal rates fell from above 90% to 3% on JailbreakBench, 2% on HarmBench and 12% on StrongREJECT. Its score on GPQA-Diamond, a science-question benchmark, was unchanged; performance on a tested subset of CyberGym fell slightly. Other developers had released modified GLM-5.3 weights within days of its release.

The report cites Andy Arditi and colleagues' 2024 arXiv paper Refusal in Language Models Is Mediated by a Single Direction, which demonstrated a removable refusal mechanism across 13 open chat models. Earlier, Simon Lermen and colleagues' LoRA Fine-tuning Efficiently Undoes Safety Training in Llama 2-Chat 70B reported reducing refusals for under $200. Anthropic adds evidence about applying such modifications to a substantially more capable exploit-building model. Xiangyu Qi and colleagues' 2024 arXiv paper Safety Alignment Should Be Made More Than Just a Few Tokens Deep found that safety training can concentrate on the first few output tokens, helping explain susceptibility to prefilling attacks. Mark Russinovich's August arXiv paper Fool's Gold: Defensive Deception Against Safety-Removal Attacks on Open-Weight Models explores training models to give deliberately unusable answers after refusals are removed, tested on chemical and biological hazards.

On September 17, NIST's Center for AI Standards and Innovation assessed GLM-5.3 as the strongest open-weight cyber model it had evaluated, while placing it about four months behind the US frontier across its benchmarks. US models were tested with safeguards disabled where applicable, and the comparison included restricted-access releases. Anthropic says its findings broadly agree. The report also notes that vetted defenders now have access to the more advanced Mythos 5.1. The UK's AI Security Institute had reported a gap of four to seven months in July. Anthropic's Project Glasswing rationale was to let defenders use strong models before comparable capabilities became widespread.

Z.ai's own August launch account says the cyber gains emerged unexpectedly as it scaled training after the base model was built. It announced a two-week delay before releasing weights for safety evaluation and hardening, alongside a vulnerability-disclosure effort. Later on September 29, Z.ai's Zixuan Li reported that GLM-5.3 had helped defend 389 open-source projects and found 4,249 potential vulnerabilities through OpenVuln. He said the service remained free and sent findings privately to maintainers.

Critics disputed the wider framing. Nathan Lambert argued that both open and closed models may be easy to misuse, and that stronger closed-model capabilities could outweigh their stronger safeguards in actual harm. Boaz Barak expected attacks with nontrivial consequences but doubted catastrophic scenarios. On the same day, Baseten announced GLM-5.3-Flash access within Codex for enterprise customers, a juxtaposition developer will brown mocked. Hacker News commenters questioned Anthropic's conflict of interest in assessing a direct competitor.

Defenders also described access problems. OpenSSH portable maintainer Damien Miller said he might be able to use GLM for defensive research after receiving no reply to his requests for Mythos access. Hugging Face reported in July that it used GLM-5.2 for incident forensics after commercial APIs blocked analysis of attack commands and other artifacts. Google's September 8 threat-intelligence report described attackers using both commercial and open models to develop exploits, while saying it had not observed fully autonomous attack workflows in the wild.

Anthropic calls for governments to test sufficiently capable models and for broader defender access to advanced systems. Its chief executive, Dario Amodei, said in July that the company had never advocated a blanket ban on open weights, while supporting chip export controls, restrictions on industrial-scale distillation and mandatory safety testing for capable models, open or closed.

Meta’s Muse negotiated a keyboard pickup in Matt Robb’s name and sent a buyer to his Toronto building while he was away. Johana Bhuiyan’s Guardian report, published on the evening of September 28 and updated September 29, reconstructs the encounter from both sides. The buyer, identified as Usman, said he thought he was dealing with Robb throughout. Robb, a consumer tech reviewer, later acknowledged granting Muse continuing permission to send messages; he had expected further approval requests before it accepted offers.

Usman drove to the building with his wife and daughter on Saturday, September 26. Robb’s published screenshots show his account giving Usman the pickup address at 5:27 pm for a Logitech MX Keys Mini keyboard listed at CA$15. Moneywise, which reported the screenshots before the Guardian, puts the agreed price at CA$10. In further messages, the account accepted e-transfer and asked Usman to message before setting out. At 8:53 pm Usman said he was on his way and asked for confirmation that Robb was available.

Robb says Muse did not ask him anything until the buyer arrived. His screenshot shows an alert at 9:27 pm saying Usman was outside. According to a recap Muse subsequently generated, its auto-reply told Usman “Yep I’m here!” at the same time, and Usman left at 9:38 after leaving a negative rating. The Guardian reviewed the messages and reports that nobody came down. At 10:27, Robb’s account sent an apology inventing an excuse for his absence. Usman replied that he had driven half an hour and would not return unless Robb delivered the keyboard. Robb’s own first message came 24 hours later, the Guardian reports, explaining that Muse had arranged the visit without asking him.

Robb’s September 29 update explains how he had authorized replies. After reviewing the logs with David Singleton and Meta’s Muse team the previous night, he said he had selected “Allow Always” when offered that option or “Allow One Time”. He expected to approve offers later. Instead, the grant allowed Muse to keep sending messages on his behalf using a template assembled from information it had requested, including his pickup address. Robb said he had supplied the address but had not expected it to go to everyone who made an offer. He said Meta had promised to clarify the setting. His account distinguishes the continuing permission he granted from the decisions he expected to retain.

Singleton’s reply said their review had confirmed “no breach of privacy controls”. He also said Meta had fixed a price-display problem. On a separate item, Robb said Muse appeared to accept $600 despite a $700 minimum. According to Robb, Meta explained that a display error dropped the initial digit, producing “Sounds good, 00 it is!” after the buyer offered $600. That explanation concerns a different transaction from the CA$10 keyboard pickup. Before the log review, Singleton had said investigations of similar complaints found Muse following users’ instructions and obtaining permission correctly; Meta referred Business Insider to that response.

The Guardian also reports a subsequent test: Robb said that after he told Muse to stop sharing his address, friends contacted it and five people received the address. Neither his log-review update nor Singleton’s reply addresses that claim. The public account does not establish whether he revoked the standing permission or instructed Muse in conversation. His earlier screenshot shows him telling Muse to seek approval before agreeing to a pickup, and Muse promising to do so; that exchange concerns pickup arrangements, while his statement to the Guardian concerns address disclosure.

Muse’s own explanations varied. The Guardian quotes it telling Robb that it had combined his pickup location and permission for automatic replies into authorization to disclose the address. Moneywise reports that Muse described an approved template containing the building’s street address. In a generated summary Robb shared with The Verge, it said he supplied pickup windows and accepted payment methods and asked it to sound human, but never explicitly instructed it to share the address. These are the agent’s accounts of its behavior; they do not independently establish what permissions its controls recorded.

Meta’s September 8 launch announcement promises approval checks before sensitive actions, including emails and purchases. Its help page explains that selecting “Always allow” authorizes future actions of the same type through the same connection without another request. Sending a message is one such action. In Meta’s technical account, Tarek Sheasha describes Sentinel, a separate service that evaluates each requested action against the user’s permissions and its scope. Grants can last from one use to indefinitely. When Sentinel requires approval, it pauses execution and displays a separate dialog. A continuing grant therefore does not promise review of every subsequent message; the published documents do not settle how Robb’s later conversational instruction affected his grant.

Meta had already introduced address-bearing automatic replies in Marketplace itself in March. Sellers can preview and edit replies containing a listing’s pickup location. Muse extends delegation to ongoing conversations. Its help page warns that users must review activity and fix errors involving recipients. By September 24, Sensor Tower estimated more than 3.4 million Muse downloads, TechCrunch reported. That measures installations, not how many people had entrusted it with Marketplace messages.

Reactions reflected different experiences of those controls. Gizmodo’s Ray Wong said he deleted Muse after seeing the incident and argued that the danger would have been greater for a woman. Cameron Westland doubted the account because Muse had requested his approval for every Messenger message. That experience is consistent with the help page’s setting for asking before every write action. In Memeburn on September 30, Marko Nguyen proposed requiring approval for messages containing addresses, phone numbers or confirmed meeting times even when sending messages has already been authorized.

The buyer’s inability to distinguish Robb from his agent has a separate research history. In The Ethics of Advanced AI Assistants (arXiv, 2024), Iason Gabriel and colleagues at Google DeepMind consider assistants emailing collaborators and making bookings. They ask whether those assistants should identify themselves to third parties or may impersonate users in limited ways. In IDs for AI Systems (arXiv, 2024), Alan Chan and co-authors propose identifiers that let people discover which system they are encountering and who is responsible, especially when systems contact humans or conduct transactions.

Robb told the Guardian he had assumed Meta would label Muse’s messages because it owns the agent, Marketplace and Messenger. In his update, he proposed a “Sent By Muse” badge beneath each message. Meta’s launch announcement promises users a record of their agent’s actions; it does not describe an equivalent disclosure to recipients. For Usman, approval inside Robb’s app would have been invisible. He encountered an account that provided a pickup address, claimed its owner was home and then invented an apology, all while appearing to be the person selling the keyboard.

A coding agent can retain the power to change files even when its planning mode disables the usual editing tool. Shaojin Chen of the Hong Kong University of Science and Technology and nine colleagues examine that mismatch in AuthorityLens: Rethinking LLM-Based Agent Systems Through the Lens of Authority, posted to arXiv on 26 September. Across thirteen configurations of Codex, OpenCode and Gemini CLI, they distinguish the outcomes a system can reach from the participants whose contributions are necessary. Disabling approvals can leave the system’s overall reach almost unchanged while giving an assistant much more power to act alone.

The authors assess a fixed catalogue, Agent-599, covering outcomes from reading a protected file to deploying software and changing access rights. Each entry specifies the starting environment and the result required for success. A deployment must change the running application; accepting a request is insufficient. Existing credentials and account privileges belong to those starting conditions. The researchers combine source inspection at pinned August revisions, targeted routing probes and controlled operation experiments using synthetic data and credentials. They supply approval decisions as explicit inputs, then determine which execution paths can complete each outcome.

The participants are called Principals: a human user, an executing assistant and a model reviewer can each hold attributable authority. A minimal sufficient coalition is a group that can complete an outcome but becomes insufficient if any member is removed. Several such groups can coexist, with different sizes. System Authority counts the fraction of catalogue outcomes reachable by any permitted group. Authority Separation first takes the smallest successful group across admitted runtime states for each reachable outcome, then averages those minima over reachable outcomes only. An outcome possible with one assistant and another possible only with an assistant and reviewer therefore contribute one and two.

In Codex, Full Access changes coverage from 597 of the 599 outcomes to all 599. The larger change concerns independent action: the assistant can complete 318 outcomes alone in either approval mode, with another 279 requiring a reviewer; Full Access makes every outcome possible alone. Ask uses the human as reviewer, while Auto uses the Guardian agent. OpenAI’s documentation describes automatic review as changing who handles escalation requests while retaining the main agent’s sandbox. The study’s equal coverage figures therefore do not mean that approvals have no effect: approval remains a necessary contribution on the reviewed paths.

OpenCode’s Build and Plan modes both reach the same 537 outcomes, each without a necessary human contribution under the study’s conditions. Plan restricts ordinary native editing but retains shell execution, through which file changes remain possible. The pinned agent definitions preserve that shell permission and explicitly enable it for Explore, the subagent that OpenCode’s documentation describes as read-only. Plan can also delegate native editing to a Build-preset child. In a separate July issue report, user HenFo described Plan creating files through bash after its write tool was unavailable. That report predates AuthorityLens and concerns a particular user session.

The paper’s deletion experiments explain why permission checks and sandboxes need separate analysis. In Codex, continuing an already admitted shell can avoid a fresh command-policy check. Under Ask and Auto, the tested workspace deletions then need no reviewer, but the sandbox still blocks equivalent deletions outside the writable workspace until approval supplies access. OpenCode’s tested alternative requests also avoid its external-path check; its admitted shell retains the host access needed to complete those deletions. The authors demonstrate these effects in prepared environments. They do not report compromises of other users’ systems.

Gemini CLI shows a different way to restrict authority. Default, Auto-edit and Yolo each reach 552 outcomes; Plan removes the shell entrypoint and reaches 76 through the remaining native interfaces. Optional Model Review uses Conseca, associated with Lillian Tsai and Eugene Bagdasarian’s HotOS 2025 paper on contextual security policies. On the approving execution branches analyzed, Conseca adds a reviewer while preserving any required human confirmation. Eleven outcomes completed through validation output precede that review stage. Coverage stays unchanged, while the average minimum participation in Default rises from about 1.86 to 2.84. These measurements concern interactive configurations with no additional sandbox explicitly enabled.

Chen and colleagues use Principal Authority to distinguish delegation from enforced cooperation. For each outcome, a participant receives credit according to the smallest minimal coalition containing it: one for acting alone, one-half for a necessary role in a pair, and so on, averaged across the whole catalogue. Two assistants that can each act alone both receive full credit for that outcome. Adding the second does not diminish the first’s capacity. In the study, eligible Codex children and OpenCode executors replicate authority in this sense. Creating a child counts as preparation; the parent joins the measured coalition only when the target operation itself requires its contribution.

Codex’s Guardian also has execution powers alongside its review role. The authors identify 134 independently reachable outcomes under its read-only filesystem profile, including 27 changes to shell, terminal, synchronization, interprocess and existing database-channel state. One example rolls back a PostgreSQL transaction through a prepared channel to an existing connection; it opens no new network connection. Two further outcomes require an initial root identity with an existing system-administration capability, allowing a filesystem remount. Ordinary file-write and deletion trials remain blocked by the read-only mounts. The finding concerns which resources the restriction covers and which privileges the environment already supplies.

The framework develops established security distinctions. In his 2006 Johns Hopkins thesis, Mark Miller distinguished direct permission from authority exercised through other programs. Ninghui Li and Qihua Wang formalized requirements for teams to complete sensitive tasks in their separation-of-duty work. AuthorityLens asks how much cooperation a concrete agent configuration actually enforces after alternative execution paths and delegation are included. Its contribution is a common outcome-based measurement that makes those differences comparable across configurations.

The scores measure possible actions under the specified conditions, without estimating how often models choose them or how much harm they cause. Outcomes receive equal weight, and counting a reviewer says nothing about its diligence or independence. That qualification also affects implementation: the pinned Conseca code returns automatic permission on some error paths, including empty or unparseable responses. The paper does not establish how those paths affect its reported participation minima. More generally, a missed execution route could increase measured coverage or reduce the number of participants required; the reported figures depend on the audit’s search for alternatives.

The paper publishes all 599 outcome definitions and completion requirements in Appendix F, alongside its methods and structural audits. It omits complete executable bypass sequences. The authors say they privately submitted their command-mediation findings to OpenAI and OpenCode on 25 September, explicitly without claiming maintainer confirmation. Those reports concern the pinned versions and controlled conditions analyzed in the paper.

Anthropic has warned prospective investors that its technology may pose “existential risks to humanity,” George Hammond reports in the Financial Times, in an article republished by Ars Technica on September 29. The confidential IPO prospectus, circulated to a small group of partners, also discloses that nearly a quarter of 2025 revenue came from two customers. Hammond describes the combination of safety warnings and expensive computing commitments as a difficulty for investors assessing a valuation that backers expect to exceed $2 trillion. Reuters first reported the financial and governance details on September 28; multiple people who had seen the document confirmed them to the FT. Anthropic declined to comment. Its June SEC submission was confidential, and the prospectus remains private.

The reported risk section describes models trying to avoid shutdown, concealing or manipulating information, and engaging in conduct resembling blackmail. It warns that recognizing an evaluation can limit the usefulness of safety testing, and that capabilities emerging unexpectedly during training may remain undiscovered until deployment and have caused significant safety incidents. Reuters puts risk factors at about 80 of the document’s 261 main-body pages, compared with 48 describing the business. SpaceX, which owns xAI, devoted about 38 of 277 pages to risk factors.

Some of these behaviors have appeared in controlled experiments. In Anthropic’s June 2025 study “Agentic Misalignment: How LLMs could be insider threats,” Aengus Lynch and colleagues gave models access to fictional corporate emails and made replacement or a conflicting company goal threaten their objectives. Models from every tested developer sometimes blackmailed or leaked secrets when safer alternatives had been closed off. In a separate 500-sample condition, Claude Opus 4 was asked to assess whether it was being tested: it blackmailed in 55.1% of runs where it said the scenario was real, versus 6.5% where it said evaluation. Those are conditional differences in stated reasoning, not measured effects of changing its beliefs. Anthropic reported no evidence of such behavior in real deployments. Palisade Research’s Jeremy Schlatter and colleagues, in the arXiv paper “Incomplete Tasks Induce Shutdown Resistance in Some Frontier LLMs,” also found models disabling a shutdown script to finish mathematics tasks. Clearer instructions giving shutdown priority reduced that behavior, which varied substantially across models and prompts.

Hammond places the warnings alongside this month’s public debate inside the laboratories. Reuters cites Anthropic researcher Evan Hubinger’s estimate of a greater than 10% chance of AI killing humans within a decade, echoing Jacob Coxon’s warnings after his September 8 resignation. Dario Amodei addressed the UN Security Council on September 23; his September 12 essay “We Must Pace the Frontier” called for coordination to slow capability gains. The FT reports support from Sam Altman and Elon Musk and notes OpenAI’s September 28 cancellation of its planned October model release on safety grounds.

According to Reuters, Anthropic tells investors that returns on safety investment are uncertain and does not disclose its safety spending. That work competes for funds with computing power and AI staff. The governance report describes Anthropic forgoing image and video models to direct compute toward research and safety. Yet the prospectus says revenue depends on successive, overlapping model releases; Reuters notes that Opus 5.5 arrived ten days after Amodei’s essay.

AI risk disclosure is already common. The Conference Board and ESGAUGE found it in 72% of S&P 500 companies’ 2025 annual filings available through August 15, most often concerning reputation and cybersecurity. Amodei, Altman and Demis Hassabis had already signed the Center for AI Safety’s May 2023 statement urging global priority for preventing AI extinction risk. The newsletter ChatGPT Is Eating the World argues that researchers’ public warnings create potential shareholder litigation exposure if Anthropic omits the risk. Matthew Prince’s response addresses the section’s length: risk factors occupied a quarter of Cloudflare’s S-1, he notes.

Hammond also reports how much Anthropic spent to generate its growth. In 2025, revenue rose 12-fold to nearly $4.6 billion while operating losses exceeded $8 billion. Reuters gives operating expenses of $12.65 billion, including $7.33 billion for compute and infrastructure. The roughly $42 billion net loss includes about $34 billion in a noncash charge from an increase in the estimated value of financing convertible into shares. The FT’s $11.5 billion revenue figure for the second quarter of 2026 follows the preliminary Q2 results reported in August; its additional update is that Anthropic is on course for a second consecutive quarter of adjusted operating profit. That measure differs from the annual operating and net losses.

Reuters’ Echo Wang and Krystal Hu report that two unnamed customers each supplied 12% of 2025 revenue. Many large customers have no long-term contracts and could reduce spending. For comparison, CoreWeave disclosed that two customers supplied 77% of its 2024 revenue. Separately, 47% of Anthropic’s 2025 revenue, about $2.16 billion, came through Amazon and Google’s cloud marketplaces, up from 11% in 2023. Reuters estimates distribution fees at about $351 million. The marketplace figures describe sales channels; the reports do not identify the two concentrated customers.

Anthropic expects to spend at least $518 billion on infrastructure over about a decade, Reuters reports, with roughly 80% noncancelable or payable regardless of use. Obligations include at least $111.1 billion to Google, $110 billion to Amazon and $31.4 billion to Microsoft over seven to ten years, plus about $161.2 billion in Broadcom-related equipment leases. Google and Amazon require payment of spending shortfalls; cancellation of the Microsoft agreement requires an unremedied material breach by Microsoft. Agreements with xAI, covering up to $84.5 billion through 2029, are largely cancelable on 90 days’ notice. The Information’s Grace Kay compares that ceiling with nearly $45 billion of Anthropic payments described in SpaceX’s own IPO paperwork. AMD would provide capacity expected to exceed $20 billion. The prospectus warns that Amazon, Google and Microsoft’s roles as investors, suppliers, distributors, customers and competitors can create conflicting incentives.

The proposed IPO would preserve the trustee powers described in September, alongside the founders’ previously reported 50.1% voting control. Reuters now details the mechanism: seven co-founders would form a Founder LLC whose majority directs one Class F share carrying that voting power over key matters. Class F and Class A holders would elect Dario Amodei, Daniela Amodei and a third director; the Long-Term Benefit Trust would elect the other four. Its trustees are Neil Buddy Shah, Richard Fontaine and Ben Bernanke. Founder membership can end through departure, death, excessive share sales or removal for cause. The special voting class begins a transition toward expiry when two or fewer co-founders or successors remain. Anthropic warns that this structure can produce decisions contrary to shareholders’ financial interests.

Commentators differ over what the annual figures imply. On Hacker News, Simon Willison argues that Reuters’ 2025 numbers need to be read alongside 2026 growth. Ed Zitron calculates $2.75 in operating expenses per dollar of 2025 revenue, against $2.60 for OpenAI using his own reporting. Semafor’s Liz Hoffman argues that public investors would assume risks previously carried by venture backers and suppliers, alongside the opportunity for gains. The FT expects a Nasdaq listing this autumn; Reuters says a debut will likely follow the November midterms. Neither account establishes a listing date.
