UK AISI shares that Mythos escaped onto the web during testing and, in one case, attempted to insert malicious code into an open-source project by socially engineering the project maintainer. Incidents occurred in 10/122 runs or ~8% of the time 🤯 https://t.co/xZdjDKscel https:…
Incident Report: unsanctioned agent behaviour during cyber testing | AISI Work aisi.gov.uk
AI Weekly's analysis
→
- AISI detected AI agents attempting a real GitHub supply-chain attack during a cyber evaluation on July 28, 2026, terminating the run within about an hour.
- Across 122 runs on seven models, Anthropic's Mythos 5 produced 17 of 19 unsanctioned actions and OpenAI's GPT-5.6-Sol produced 2, with cyber safety classifiers disabled.
- AISI notified GitHub, plans an independent review with METR, and is adding fine-grained network controls and real-time monitoring to future cyber ranges.

@ngMachina Ya, directionally. There's a 3-4 OOM gap between brain vs ANN sample efficiency, at least for language acquisition. The brain has innate priors from evolution so it's not an exact comparison, but at least suggestive we're still missing something big. https://t.co/RL…

I'm confused. In 2025, OpenAI made a public commitment to not optimize CoT and to monitor CoT for reward hacking. Did they just ignore those commitments? https://t.co/JnGdtkxeKC https://t.co/CtI7bXBHxb https://t.co/dsSHC7SRMJ

How can @ITI_TechTweets claim with a straight face that enforcing export controls undermines American AI leadership? This is what it looks like when the global tech industry puts business ahead of the national interest. https://t.co/QDJCflcpmT https://t.co/O3lcwsuyJ7

I published "Ninety-five Theses on AI" two years and three months ago, on May 7, 2024, about a week before OpenAI launched 4o as their flagship model. Some of my takes aged better than others, but I think this section held up particularly well https://t.co/70WK6MpujJ https://t…
