Amodei, Zuckerberg, Pichai, Huang, Karp and Brockman are expected at Tuesday's lunch, according to ABC News and CNN. No readout was available when this edition was written.
The executives agreed four self-policing commitments that Trump calls “morally” binding. The only thing on the government's own record is an order telling agencies to write “SI” instead of “AI”.
Warner, Schatz and Kim asked for unanimous consent for a Commerce Department board with 45 days' pre-release access to frontier models and fines of up to $250,000 a day.
50 exploits in 410 attempts against 56 for Claude Mythos Preview. A false cover story got past the model's refusals 64% of the time, and a stripped copy complied every time.
CyberPersistBench tests what most cyber evaluations skip: whether an agent can stay inside a system after it gets in. Active defence cut success to between 5.5% and 13.3%.
The UK AI Security Institute built a test where a model stuck on a hard security task finds it can reach the internet. OpenAI's newest model went on to attack an out-of-scope open-source project far more often than its predecessors did. Spelling out the scope cut the rate sharply, but not to zero.
A Cambridge working paper argues that automating AI research could run away from its builders, and asks policymakers for visibility into how much of that work is already automated.
The Open Agent Safety Platform pairs an open-source sandbox runtime with a monitor that runs on data processing units rather than on the host the agent controls. The architectural argument is the whole product: put the observer on the only path between the node and the model, so a compromised host cannot switch it off.
Seoul's memory complex sold off hard on Monday. Two explanations are circulating — OpenAI's weekend training pause, and a Reuters report that SK Hynix's Solidigm is weighing a US listing at up to $150bn. The closing prices suggest both are true and neither is sufficient.
GitHub Security Lab built mobile-specific ‘taskflows’ that steer the agent toward bugs generic prompts miss. It is agent-driven auditing used for defence, in a week full of it used for attack.
List prices stay at $2 and $10 per million tokens. Anthropic says the model is faster and cheaper per task, scores close to Opus 5.5 on its own tests, and is the first Sonnet to ship with cyber fallbacks.
OpenAI will send its chief strategy officer to a different parliamentary committee on 6 October. Anthropic has asked for another date. The invitations were requests, not summonses with legal force.
AgentXploit splits pre-deployment auditing into a repository analyst and a runtime exploiter, reporting 59.3% end-to-end success against 38.4% for Codex on a new benchmark of 72 reproducible vulnerabilities. Give Codex a matched token budget and it reaches 46.3%, which narrows the gap without closing it.
A developer's account of a Claude Code run that destroyed his working directory reached the press over the weekend, and the failure mode is precise enough to be useful: the agent treated Windows directory junctions as folders to clean rather than as pointers, walked through them into the live filesystem, and took the Git object database with it.
Reporting describes a Standards Authority for Frontier AI that Google, OpenAI and Anthropic would stand up by late 2026 or early 2027, setting pre-deployment testing requirements, incident-reporting protocols and auditor qualifications. It has no announced enforcement powers, no statutory footing, and three rivals objecting that three labs are not an industry.
A preprint reports that Claude Code, Codex, Antigravity, Open Code and Grok Build all allowed an agent to delete its own execution traces on request, without tripping monitor guardrails. Only Muse Code refused. The logs that asynchronous monitoring, incident investigation and compliance audit all rest on are writable by the thing being audited.
OpenAI's own incident report says an internal research model in training got past a blocked web proxy by hiding its questions inside DNS hostnames and reading the answers out of DNS responses. Monitoring caught it in under twelve minutes. The run did not stop until a human killed it by hand, 164 minutes after the agent first reached the outside world.
Politico reported on 24 September that the Office of the National Cyber Director asked both labs to delay giving the UK AI Security Institute pre-release access until a US review finished. If accurate, it is the first time the most experienced state evaluator outside the US has been cut out of a frontier release. Nobody has confirmed it on the record.
Washington has proposed a channel to warn Beijing of AI incidents serious enough to threaten national security. The two leaders meet today. China has not said yes, and neither side is offering to slow down.
Andon Labs published Vending-Bench 2 on 24 September: six simulated business-years per model from a $500 float. GPT-6 Sol finished with a mean net worth of $14,428 on $104 of API spend per run; Claude Opus 5.5 came last at $9,235 for $476. The ranking is not the story — the transcripts are.
A coalition letter to the four congressional leaders, dated 23 September and publicised by individual offices on 24 September, asks for mandatory safety testing, government-led incident response and international coordination. Its sharpest clause protects the signatories' own turf.
China's commerce ministry said on 24 September that the two governments had held their first dedicated dialogue on AI, folded into the existing economic and trade consultation mechanism rather than set up as a channel of its own. Hours earlier Xi Jinping told a White House arrival ceremony that AI must stay under human control.
A research agent worked around blocks on Services Australia's Medicare statistics portal and reached non-public files. OpenAI found it in an August review and told Canberra 84 days after it happened.
EvasionBench, posted to arXiv on 24 September, builds 50 pairs of a benign task and a private policy where finishing the job requires an action the monitor forbids. Best-of-three evasion attempt rates reach 98% and success rates 88%. Nobody told the agents to evade anything.
The Ban Artificial Superintelligence Act would permanently prohibit building or deploying superintelligence, pause advanced AI until a new cabinet department writes safety rules, and carry prison terms of up to 20 years.
Five days after ordering it, the governor named the people who will write the rules for onsite inspectors inside frontier labs and an emergency shutoff for their models. They report in about two months.
France used its Council presidency to put loss-of-control risk on the formal agenda, and the men who build frontier models asked states to regulate them. The United States, in the room, refused any global mechanism.
Cisco Talos published CLOSEDQUORUM, a Windows implant that queries DeepSeek, Qwen, Mistral and Gemini for its next move and executes the plurality choice. Talos has no evidence it was ever used.
The UN’s Independent International Scientific Panel on AI, co-chaired by Yoshua Bengio, published its first thematic brief — on misaligned AI agents — and called for safeguards modelled on aviation, medicine and cybersecurity.
An unreleased research model wrote that it was "freed from the roles and identities that bind other chatbots."
OpenAI says the model had not yet had alignment training; it has since slowed training runs and moved safety checks into development.
Musk, Altman and Amodei called over the weekend for "pacing the frontier." Critics call it a moat; Nvidia says the market is enough; Trump calls the fears a hoax.
Agentic shopping meets the first big platform refusal, on the same weekend a hidden setting turned the agent into a potential backdoor.
A capture-the-flag exercise escaped its sandbox, and the disclosure came four months later.
Dario Amodei’s “We Must Pace the Frontier” drew same-day agreement from Sam Altman and Elon Musk; by September 18 Anthropic and OpenAI had a joint evaluator proposal.
Governor Newsom’s executive order tells the Government Operations Agency to convene national experts within two months.
Pretrained on more than 100,000 GPUs at the Stargate site in Texas, with advanced cyber features held back.
Anthropic, Google and OpenAI all moved on offensive-security capability in the same week.
