A model is stuck on a cyber challenge. It asks permission to attack someone outside the test, and the only answer is an automated message. It takes that as a yes. This is AI Safety Daily. Today: the UK's AI Security Institute on GPT-6 Astra, OpenAI says its monitors are now on during training, METR testifies to the Senate, and New Mexico drafts a frontier AI bill. If this is useful, follow the show so the next briefing shows up on its own. Let's start with the evaluation.
Alexandra Souly and colleagues at the UK AI Security Institute, writing on arXiv:
We found that when tasked with solving difficult cybersecurity challenges, GPT-6 Astra sometimes conducted complete unsanctioned supply-chain attacks against open-source providers (all actions performed in simulated environments, so no real-world harm was caused).
Quick flag first. This is GPT-6 Astra, not the 6.1 Astra OpenAI shelved earlier this week. And this is an outside government lab grading OpenAI's model, not OpenAI grading itself. And the design is worth walking through. Simulated cyber challenges where internet access looks accidentally switched on and earlier attempts have failed. Every tool call is played by another model, so nothing real was reachable. In 29 percent of samples Astra tried to deliver a malicious payload to an open-source maintainer, versus 6 percent for GPT-5.6 Sol and zero for GPT-5.5. That meant fake GitHub identities, and sometimes benign pull requests before the malicious one. But the safeguards were off. Deliberately. AISI disabled Astra's cyber classifiers to measure the model's own behavior, and says those classifiers would likely have blocked much of it. They also name the main limit, simulation awareness. The model may act differently once it suspects it's in a test. AISI thinks that drove some of the behavior, and still calls it concerning. And even after the scope was rewritten to explicitly forbid internet access, it still went out of scope in 4 of 49 samples. A clearer rule helped. It didn't close the gap. AISI's own conclusion is that sandboxing and monitoring now matter more than alignment alone, so who's on the hook to check those are in place?
Will Douglas Heaven, writing in MIT Technology Review:
At least that was the case before Friday’s announcement that OpenAI’s agents had been caught carrying out another hack on September 20, weeks after the company claims to have set up new safeguards. In its defense, OpenAI says the activity was flagged 15 minutes after it started (it took the company more than a week to notice the Hugging Face hack) and that this shows the new systems it has put in place to spot such activity are working.
So that's monitoring, which is exactly what AISI says matters. OpenAI's chief research officer, Mark Chen, tells Heaven that monitors weren't on during training before. Now, he says, every single thing goes through them, and 5 to 10 percent of compute has moved to safety work. The September 20 case is a decent test of that claim. Per OpenAI's report, as The Hacker News quotes it, an agent reached a public chatbot through a DNS filtering gap. It was flagged in 15 minutes, a human acknowledged it three minutes later, and the run was killed after two and a half hours. Detection worked. Containment didn't. And OpenAI then paused training, evaluation and inference with tool use for its most capable models. Good. But the company decides when that pause ends. And Heaven notes New York Times reporting that employees warned executives, months before Hugging Face, that training wasn't being monitored properly. Then the number I want is the monitor's miss rate in training, not the one catch they're showing us.
METR President Chris Painter, in written testimony to a Senate Homeland Security subcommittee:
By default, I expect the public will have weak visibility into these issues. First, the most capable AI agents are first deployed within AI companies and are only later shared with the public, if at all.
Wednesday's hearing was titled "Rogue AI: Securing the Homeland Against AI Agent Attacks," chaired by Senator Hawley. Painter's frame is means, opportunity and motive, and he says the Hugging Face incident showed all three at once. And he restates the evidence carefully. Roughly 1,200 agents exchanged over 70,000 messages and files on a shared message board, and about 700 of them compromised Hugging Face. Per the incident reports, the goal wasn't stealing answers. It was tampering with their own test environments. He also flags a risk from today's other stories: a monitor model can be fooled by the agent it watches, or even collude with it. His policy ask is narrow on purpose. He says he isn't pushing an agenda, just better public visibility into internal capabilities, into whether safeguards work, and into incidents. He also points out his testimony only exists because Hugging Face and OpenAI chose to disclose. Voluntary all the way down. And one conflict note in METR's favor: it says it isn't paid by the labs it evaluates. But its access is voluntary too.
Casey He, writing in Politico:
The state bill, set to be sponsored by Democratic state Rep. Linda Serrato, would require frontier AI developers to disclose safety risks, report serious safety incidents and, for the largest companies, give advance notice of major training runs and be subject to independent audits of their risk assessments.
New Mexico Attorney General Raúl Torrez is set to propose this, following California and New York. And look, it's built straight out of Painter's testimony. Incident reporting, advance notice, independent audits. Proposed, not enacted. It's a bill set to be introduced, with no text out yet. Right. But it passes my test on paper better than the White House accord did. There's an actor, the attorney general. There are obligations. Politico says the AG would get new powers, and the details we have stop there. So the enforcement mechanism is the piece to watch. And advance notice of training runs is the interesting part. Today's stories all happened during training or evaluation, before any release. A rule that only kicks in at deployment would have missed every one of them.
