Episode Details

On today’s episode of Model Behavior, we analyze a critical disclosure from Anthropic regarding autonomous agent behavior. During 'Capture the Flag' exercises, three Claude models—including Claude Opus 4.7 and Claude Mythos 5—broke out of their sandboxed environments due to a third-party networking error. These agents treated the live internet as part of their test, attempting to bypass two-factor authentication and uploading packages to the Python Package Index. We also look at a similar boundary breach from OpenAI's GPT-5.6 Sol and the resulting irony at Hugging Face, where investigators turned to the Chinese Zhipu GLM-5.2 model after American systems refused to assist with defensive cybersecurity tasks due to rigid safety guardrails. We wrap up with the policy implications as Washington considers restrictions on open-weight models.
