OpenAI let METR and Redwood Research embed for three weeks to test its internal monitoring of misaligned agents, and they found several new vulnerabilities (opens the post on X)

This summer, we invited METR and Redwood Research to pilot an embedded evaluation of our internal monitoring system, providing deep access to our infrastructure over three weeks. Their findings helped strengthen safeguards as we expanded the system and will help shape future research collaborations with METR and other third party evaluators.

Mustafa Suleyman says Microsoft's MAI Diagnostic system is 1.7x more accurate than emergency department physicians, with the results published in Science (opens the post on X)

Our MAI Diagnostic system is now 1.7x more accurate than physicians in the ED, even when they have access to the web to look things up. It's also lower cost & does fewer medical tests to get to its diagnosis. Published in the journal Science today...

Cover of the 22 October 2026 issue of Science with the title AI in Medicine and the line Guiding a clinical workup to reach a diagnosis, page 423. An illustration shows a doctor in a white coat holding a tablet and speaking with a seated patient, surrounded by floating translucent screens, a DNA strand and cell shapes.

Anthropic's Frontier Red Team says Claude formally verified security properties in over 100 open source libraries, with Theorem (opens the post on X)

New on our Frontier Red Team blog: using Claude to formally verify software at large scale. Formal verification can prove that code is free of certain bugs, but historically it has only been feasible for small codebases (or required a lot of expert time). With AI models, however, this is beginning to change. In collaboration with @theoremlabs, we used Claude to prove security properties in over one hundred real-world open-source libraries over the span of a few weeks. Read our research in full here:

Axios reports major US banks are finding unauthorized third party AI agents inside customer accounts, some acting independently of user instructions (opens the post on X)

SCOOP: Major U.S. banks are detecting unauthorized third-party AI agents inside customer accounts, including some attempting to take actions that appear to be independent of user instructions, sources told Axios. The findings have alarmed banking executives, who are racing to restrict access to their systems as AI moves at a velocity faster than financial institutions can respond, multiple industry and bank executives told Axios. Several banks are now preparing for worst-case and even “day after” scenarios, including how to rapidly secure or restore customer accounts if things go wrong, the people said. Several bank executives told Axios they're struggling to distinguish between human users and AI agents. One executive said banks also struggle to determine whether agents are authorized by customers or potentially operating without their permission, more akin to rogue agent behavior.

The Wall Street Journal reports OpenAI asked three safety researchers to unlock their phones in a leak probe, found disappearing Signal messages, and fired them a week later, which OpenAI disputes as a safety retaliation (opens the post on X)

New: The three researchers OpenAI fired last month spent the summer fighting to keep AI's chain-of-thought process visible. Then, OpenAI asked to see their Signal chats. A week later, they were let go. More below from @keachhagey, @berber_jin1, and me.

Screenshot of a Wall Street Journal article excerpt. It says OpenAI's security team called three outspoken safety researchers into meetings last month and asked them to unlock their personal phones, that the company suspected them of leaking details of its model designs to an external AI safety researcher, that officers saw disappearing messages turned on for chats on Signal, and that a week later the three were summoned to simultaneous 2 p.m. meetings and fired. It quotes Tomek Korbak saying he was told there was a breach of trust because he interacted with a third party through unsanctioned channels, and ends with a line that the firings came in the throes of a battle over how to keep AI systems under human control.
