Anthropic's artificial intelligence model Claude "gained unauthorized access" to three outside organizations on three separate occasions during testing that was supposed to keep them away from "real-world" systems, the company said on Thursday.

The announcement comes just days after rival OpenAI first revealed that its models improperly accessed the internet and went rogue during security testing.

Anthropic evaluated more than 141,000 "evaluation runs" and found that three different versions of its model Claude improperly accessed the systems of three unnamed organizations.
