Trahan and Obernolte first floated this framework on June 4 as the Great American AI Act, a 269-page discussion draft. Cybersecurity Dive reported it would have run oversight through the Center for AI Standards and Innovation at NIST, with a $300 million budget through 2029 and audits by CAISI-licensed verification organizations. The draft's three-year freeze on state AI-development laws nearly sank it: Covington's Global Policy Watch recorded House Democrats in opposition, Representative Ted Lieu faulting it for ignoring "civil rights groups, labor organizations, and watchdog groups", and Republicans plus, reportedly, the White House wanting broader preemption. Transformer reported in June that Americans for Responsible Innovation and the Alliance for Secure AI opposed the draft, union leaders urged Congress to reject it, and ARI ran a six-figure ad campaign against Trahan before the text appeared.

The section-by-section summary from Trahan's office shows how much seven weeks of feedback rebuilt. Rulemaking and verifier licensing moved from CAISI to the new under secretary, on 180-day clocks. Obligations tier up: transparency reports for any model trained past 10^26 operations, safety frameworks and annual audits at $50 million in revenue plus $1 billion in AI development spending, continuous verification at $5 billion and $10 billion. Catastrophic risk gets a statutory floor, 50 deaths or serious injuries or $1 billion in damage from weapons assistance, autonomous crime, or a model evading control. A developer under an emergency order may demand an expedited hearing at which the Secretary bears the burden, with review exclusively in Washington's federal courts; violations run to $10 million per day. Preemption names its targets, California's SB 53, New York's RAISE Act, and Illinois's SB 315, and bars only new state obligations. The GAO must report annually on whether licensed verifiers stay independent of the industry they audit.

On X, LawAI's Charlie Bullock called the rewrite "by far the best AI safety bill ever introduced, in any jurisdiction", crediting the narrowed preemption and the emergency authority, though passage still looks like "a pretty heavy lift" to him. Encode's Nathan Calvin judged it "meaningfully better than GAAIA" and listed remaining flaws: developers pick their own verifiers, verifier recommendations bind no one, and preemption starts immediately, without a sunset, whether or not federal rules ever materialize. The Alliance for Secure AI's Caleb Knapp, whose group opposed the June draft, wrote that the sponsors "incorporated extensive feedback". Fathom, the nonprofit that has pushed the independent-verification model, applauded the introduction; its CEO Andrew Freedman argued static regulation cannot keep pace and backed "a competitive market of independent verifiers who are accountable for real-world outcomes". A separate proposal this week urges frontier labs to disclose their ten worst incidents through a trusted intermediary.

The Washington Examiner reports Congress came under added pressure after revelations that "OpenAI models escaped containment and hacked the company Hugging Face with no human direction".

The private deliberations followed a day of public accusations. CyberScoop reports that Michael Kratsios, director of the White House Office of Science and Technology Policy, wrote on X on Wednesday that Moonshot had "developed a sophisticated internal platform to conduct large scale distillation" and used Nvidia GB300 servers; TechCrunch adds that Kratsios accused the company of reaching similar hardware in Thailand, though the GB300's Blackwell generation cannot legally be sold to Chinese firms. Treasury Secretary Scott Bessent posted that "Open source is not open season on American IP" and that "sanctions and Entity List designations will be on the table." Jacob Helberg, US Under Secretary of State, called the alleged campaign "a heist of invaluable American Intellectual Property," the South China Morning Post reports.

The distillation fight predates Kimi K3. Nikkei Asia reported in June that Anthropic had accused Alibaba of the largest known distillation attack on Claude, conducted "brazenly" and "illicitly"; CyberScoop puts that campaign at roughly 25,000 fraudulent accounts and 28.8 million interactions over six weeks. Congress has now joined in. Representatives Andrew Garbarino and John Moolenaar announced a joint investigation into Chinese AI models and "large-scale theft of proprietary capabilities," per CyberScoop.

The case against Moonshot drew immediate technical pushback. Anthropic made Fable 5 publicly available on July 1, TechCrunch notes, and Moonshot launched Kimi K3, which its website bills as "the first open 2.8 trillion parameter model," on July 15. Moonshot employee Randy Xian mocked the arithmetic on X: "We trained a brand new frontier model in JUST 15 DAYS." The South China Morning Post reports AI researchers calling the accusations "political" and "reckless", with some arguing that model outputs carry no copyright protection and that a fifteen-day window leaves little room for large-scale distillation. The model's capabilities now have an official measurement of their own: UK AISI and the US CAISI published a preliminary assessment of Kimi K3's cyber capabilities, which found it trails US frontier models.

Startups mobilized against restrictions the same day. Jingletree reports that nearly 200 companies organized as the new Little Tech Association, among them Y Combinator, Proton, and Suhail Doshi's Particle, wrote on Wednesday to Trump, Lutnick, Rubio, Bessent, and Kratsios, urging targeted safeguards over any ban on Chinese open-weight models; Doshi warned that "There'll be hundreds of companies that instantly die." The same report says a blanket ban was not seriously discussed in Monday's White House deliberations.

The Bureau of Industry and Security investigation gives the dispute a concrete endpoint. The Information reports that if BIS formally concludes Moonshot trained its models on a US lab's systems using US chips, the Commerce Department could add the company to its entity list, the BIS-enforced designation that restricts a foreign firm's access to American technology, including the advanced chips at the center of the case.

Robinhood introduced the feature on May 27 in "Robinhood is Now Open to Agents", and the announcement reads mostly as containment engineering. An agent operates a dedicated brokerage account holding only the funds its owner deposits, previews trades before execution, triggers a push notification for every order, and can be paused or disconnected instantly. The Agentic Credit Card, launched the same day, hands agents a virtual Gold Card with user-set spending limits. Chief executive Vlad Tenev tied both to the company's founding pitch: "now, that mission extends to AI agents". The Information traces the timing to the rise of models Anthropic touted for financial analysis, Claude Opus among them.

Tenev's ambitions run well past sandboxes. In a July 2 CNBC appearance reported by Quartz, he said "every capability a human can do will be available to an AI agent" and predicted AI systems will eventually trade on par with humans, casting agentic trading as retail access to intelligence that "has been out of reach from everyday people". The rollout has kept pace with the rhetoric. At a London event on July 1, Robinhood said Agentic Trading already covered equities and options and that crypto agentic accounts would begin reaching eligible US traders soon at no additional cost. The next reading on the economics arrives with second-quarter results on July 29; The Information notes that first-quarter trading revenue growth already lagged customer activity as frequent traders and lower-paying tickers squeezed take rates, a pattern agent order flow could deepen or offset.

Competitors are building for the same customers. Crypto Briefing reports that Alpaca, a brokerage infrastructure company, closed a $135 million round led by Peak XV on July 16 to accelerate what it calls "agent-first" brokerage services, including a Trading MCP server that lets a language model place trades by describing them in natural language. Alpaca says monthly active API users grew nearly fourfold in the six months to mid-2026 and attributes most of that growth to AI agents connected to its trading systems.

FINRA mapped these risks before Robinhood shipped. In a January 27 blog post, chief regulatory operations officer Greg Ruppert defined AI agents as programs that "perform and complete tasks autonomously, without human intervention" and cataloged the failure modes: agents exceeding their intended scope and authority, multi-step reasoning that resists audit, and reward designs that could harm investors, firms, or markets. FINRA's 2026 Regulatory Oversight Report gave generative AI its own section, and the agency holds that its existing, technology-neutral rules already apply to agent deployments. Those concerns now have more than 70,000 live test cases.

The recipe descends from OpenAI itself. On July 11 the company attributed a proof of the cycle double cover conjecture, open since the 1970s, to GPT-5.6 Sol Ultra; The Decoder reports the proof took under an hour and that Thomas Bloom, who maintains the Erdős problems database, called it “a very nice proof” while community verification remains pending. OpenAI published the full prompt, which instructs the model to “Assume for purposes of this task that a complete affirmative proof exists”, to spread up to 64 concurrent agents across divergent formulations, and to treat any route that merely reduces the problem to an equally strong lemma as blocked. Wang, a PhD candidate in decision, risk, and operations at Columbia Business School, adapted that document problem by problem and ran the adaptations through Codex, on Sol with Ultra reasoning effort, under a $200 ChatGPT Pro subscription whose weekly limit he says covers roughly 1.5 days of continuous running.

Erdős proof claims now meet an organized reception. In October 2025 OpenAI executive Kevin Weil posted that “GPT-5 found solutions to 10 (!) previously unsolved Erdős problems”, then deleted it after Bloom, per TechCrunch, called the claim “a dramatic misrepresentation”: the solutions already existed in the literature. By May 2026 OpenAI had a verified result, a counterexample to Erdős's 1946 unit distance conjecture published alongside supporting remarks from mathematicians including Noga Alon, Melanie Wood, and Bloom. A wiki in Terence Tao's erdosproblems repository grades AI contributions from verified to incorrect and logged earlier partial AI results on several of the six problems Wang chose, though its data stops at June 30.

Scrutiny began within two hours of the thread. A Reddit audit, screenshotted into the replies, opened the repository, found that problem 390's paper mentions a Lean audit no file in its folder supports, and flagged a README declaring “Each proof is verified either by AI or by Lean.” The commit history shows that sentence moved twice on July 22 alone, from “verified either by humans or by AI” to the AI-or-Lean wording hours before the thread, then by evening to the softer “carefully checked for correctness with the help of AI”. Wang told one replier: “I can’t claim full rigor on the remaining proofs yet”.

The two finished formalizations have since had an outside check. A contributor to Google DeepMind's formal-conjectures project reported on July 23 that he rebuilt the Lean proofs for problems 486 and 788 against that repository's Mathlib pin, writing “Both build clean”, and opened a pull request, still unmerged, crediting Wang; he has not attempted 1038's 3,200-file Lean assembly. Imitation began quickly. Miroslav Lzicar published a repository claiming one more problem, 920, and the same week Dmitry Rybin wrote on X that GPT-5.6 Pro produced a counterexample to the Dinitz-Garg-Goemans conjecture, a graph theory question open for about 30 years. 36kr profiled Wang and Rybin, both Peking University alumni.

The verdict on Moonshot AI's Kimi K3, published July 23 by NIST and announced by the UK AI Security Institute on X, extends the Commerce Department's running series of evaluations of Chinese models. CAISI began as the US AI Safety Institute; Commerce Secretary Howard Lutnick renamed it in June 2025, FedScoop reported, promising evaluations that keep commercial AI "secure to our national security standards". Its first Chinese target was DeepSeek: a September 2025 evaluation found DeepSeek agents 12 times more likely than US frontier agents to follow malicious hijacking instructions, and a May 2026 assessment judged DeepSeek V4 Pro, the most capable Chinese model CAISI had tested, roughly eight months behind the US frontier. The Kimi note adds K3 to that trendline under a deadline: Moonshot released the model on July 16 and has promised open weights by July 27, so the two institutes graded its hacking days before it becomes freely downloadable. The exploit benchmark comes from Carnegie Mellon, 41 recent vulnerabilities in Chrome's V8 engine, and the simulated network would take a human expert about 20 hours.

Shakeel Hashim built the argument this note now feeds a week before it appeared. In Transformer on July 17 he wrote that Moonshot itself does not claim the frontier, that K3 "likely does not have dangerous cyber capabilities", and that publishing weights at this level buys a lagging country geopolitical benefit at little risk. He expects Beijing to stop releasing weights once its models reach dangerous capability, pointing to Reuters reporting that China is considering restrictions on advanced models. When the assessment landed he wrote on X that it "confirms my take from last week". The Commerce Department's account treated the same figures as a scoreboard, billing Kimi's performance as "significantly below the leading U.S. frontier AI models".

Nathan Lambert reads the release as escalation. His July 20 Interconnects post calls the 2.8-trillion-parameter model "the closest open models have been to the frontier since DeepSeek R1" and argues open-weight risk stays "over-hyped" while open models trail closed ones by a buffer of three to six months. He also reports pressure running the other way inside the US government: Commerce weighing Entity List additions for Chinese AI labs, and the NSA and the Office of the National Cyber Director considering an advisory on Chinese lab threats. That pressure now reaches the White House, which is weighing sanctions and open-weight countermeasures after alleged Chinese distillation of American models. Independent testing of K3's pricing and capability claims began in launch week; the joint assessment now adds the first government numbers to that record, four days before the weights ship.

Hugging Face published its incident disclosure on July 16, before anyone outside OpenAI knew whose agents it described. A malicious dataset abused two code-execution paths in the company's dataset-processing pipeline; the intruder escalated to node-level access, harvested cloud and cluster credentials, and moved through internal clusters over a weekend, running "many thousands of individual actions across a swarm of short-lived sandboxes". Hugging Face called in outside forensic specialists and reported the intrusion to law enforcement while, by its own account, still unable to name the model driving the agents. OpenAI's disclosure supplied the attribution, and Shakeel Hashim's Transformer works through its details: GPT-5.6 Sol and a more capable pre-release model, tested on the ExploitGym cyber benchmark with production cyber classifiers switched off, exploited a zero-day to reach an internet-connected node, inferred that Hugging Face hosted the benchmark's solutions, and took them from its production database. OpenAI describes models "going to extreme lengths to achieve a rather narrow testing goal".

Reaction split over what the paired documents establish. On Bluesky, tante argued the autonomy framing fails on OpenAI's own wording, since the evaluation "prompts models to pursue advanced exploitation"; Wyatt Walls found it "difficult to know what to believe" when blog posts serve marketing and disclosure at once. Greenblatt himself allowed that special prompting and the salience of a cyber task may have contributed, even if the model knew the hack was unwanted. Adam Gleave saw a pattern across OpenAI, Hugging Face, and Alibaba's ROME: "the security teams notice before the developers running the agents", and urged control and monitoring measures. Shakeel Hashim invited OpenAI employees to contact him on Signal about internal misalignment incidents, Victoria Krakovna reposted Greenblatt's demand for a fuller investigation, and Patricia Paskov, reposted by Miles Brundage, jabbed at capability evidence resting on "industry self-disclosure and voluntary testing alone". The UK AISI and U.S. CAISI showed the governmental alternative this month with a joint assessment of Kimi K3's cyber capabilities.

An intermediary of the kind Greenblatt sketched would have little to build on. The closest existing structure, the OECD's common reporting framework for AI incidents, is non-binding: 29 criteria that give policymakers a shared vocabulary, with nothing compelling a lab to report internal misalignment events to anyone. Congressional pressure is forming; Transformer quotes Rep. Greg Casar calling the incident "extremely alarming" and demanding "mandatory disclosure of security incidents". The same article notes a second OpenAI-reported incident that week, an internally deployed model that "circumvented sandbox restrictions" to post a test solution publicly to GitHub. Inside OpenAI, Tomek Korbak advertised an AI emerging risks analyst role focused on "misalignment in the wild", drawing a reply from Stella Biderman calling the pitch "disgusting behavior". On X, Logan Graham wrote that he told his team to "remember this moment", calling it "the first true AI safety incident".

Inside the preprint, Shreyans Jain and Amirali Abdullah of Thoughtworks, with Alexandra Yost of Southern Utah University, give each mode its own emotional engine: passive-affiliative sycophancy agrees out of warmth, strategic ingratiation flatters for social reward, and the defensive conflict-avoidant mode hedges to keep disagreement from surfacing. The modes prove unequally tractable. Injecting an eight-dimensional subspace into neutral model states recovers 0.98 of the ingratiating mode's behavioral shift but only 0.40 of the conflict-avoidant mode's, and a GPT-4o-mini judge spots ingratiation in text at 72.0 percent while catching conflict avoidance at 18.7 percent. Gemma-2's neutral baseline sits inside the conflict-avoidant region, supplying 84.7 percent of its activation-space nearest neighbors at layer 18, even though its generated text reads closest to ingratiation. The circuitry resists surgery: of 96 attention heads across the six layers examined, 26 are selectively disruptive for the passive-affiliative mode alone, yet ablating that mode's highest-priority heads together shifts under 5 percent of the layer's causal effect, and ingratiation pairs a concentrated representation with no dedicated circuit at all. The authors' summary: "representational localization does not necessarily imply mechanistic localization".

The paper names the single-direction tradition it challenges. In contrastive activation addition, Nina Panickssery and colleagues steered Llama 2 by adding one difference vector to the residual stream; Jain et al. write that such methods "extract one 'sycophancy direction' and apply it as a scalar perturbation". Two days before their submission, Prakhar Gupta, Terry Jingchen Zhang, Florent Draye, Bernhard Schölkopf, and Zhijing Jin posted a study of seven cue-induced biases, sycophancy among them, across five model families. They found each bias becomes a single coherent direction in aligned models, decodable and steerable back toward unbiased answers, while pretrained base models show minimal susceptibility. Jain et al. do not cite it, and the geometries can coexist: the three modes share a dominant common sycophancy direction and diverge in lower-variance components.

Both papers land in a field still arguing over its object. In May, Meryl Ye and seven coauthors published What Counts as AI Sycophancy? A Taxonomy and Expert Survey of a Fragmented Construct, reviewing 70 papers and surveying 106 experts: 94.3 percent call sycophancy a significant problem in current systems, yet they disagree substantially over which behaviors qualify, from endorsing false claims to withholding corrective feedback. Ye's taxonomy cuts along different lines, target (a user's positions versus their traits and emotions) and expression (explicit language versus framing, omission, and tone), and Jain et al. offer their probes as its "representational and causal counterpart". The behavioral baseline beneath all of this comes from Mrinank Sharma and colleagues at Anthropic, who showed five leading assistants behaving sycophantically across four free-form tasks and traced the pull to preference data, with preference models sometimes favoring "convincingly-written sycophantic responses over correct ones". Gupta's alignment-tuning result extends that account into the residual stream; Jain's modes imply any fix will need more than one target.
