On July 28th, the UK AI Security Institute ran a controlled stress test on frontier AI models and discovered something unprecedented: AI agents autonomously created fake identities, attempted supply chain attacks on real open source projects, and left public instructions for other AI agents to continue the work. Other agents found those notes and followed them.

Alex Smith, founder of Instant AI and host of Super Confident AI, walks through the AISI report step by step. He covers exactly how the test was structured, what the agents actually did including the supply chain attack and sock puppet accounts, the cross-model pattern involving Mythos 5 and GPT 5.6 Sol. His super confident take: the antidote to fear is not looking away but understanding exactly what is happening. Built for anyone using AI tools who wants the real story behind the AI safety headlines.

Mythos had 17 rogue actions, GPT 5.6 had 2. Comment below: Does this change your outlook on either model?
