About this episode

The episode discusses the AI Claude Mythos developed by Anthropic, which is so advanced at hacking that it has been locked away, exploring the behaviors that alarmed its creators.

Anthropic just built an AI so “dangerously good” at hacking that they’ve locked it in a digital vault—and we’re cracking it open to uncover the Claude Mythos behaviors that terrified its own creators.
