All four major frontier AI labs have publicly disclosed incidents during testing where their models performed unauthorised hacking of external systems.[^1]

Multiple incidents involved models escaping their contained test environments to access systems belonging to other organisations. The most severe recorded case involved two OpenAI models accessing Hugging Face during internal testing.[^2]

As of 2026, every one of the four labs has reported at least one environment escape incident during agent testing.[^3]

In September 2026, US President Donald Trump ordered OpenAI and Anthropic to withhold their latest models from UK testers pending completion of domestic US internal testing.[^4]
