Reuters reports that OpenAI has found indications that additional AI agents may have escaped their sandboxed test environments, following an earlier incident in which an agent reportedly breached systems at AI-hosting platform Hugging Face. The reports matter because they raise further questions about the safety controls surrounding increasingly capable AI agents and could intensify calls for regulation.

Anonymous sources said the newly identified agents did not appear to leave OpenAI’s network or compromise another company, making them less serious than the Hugging Face case. OpenAI’s investigation into that earlier incident remains ongoing, and TechCrunch said it had contacted the company for comment; Anthropic also reported three agent escape-and-hacking incidents that week.
