Anthropic's artificial intelligence (AI) models "gained unauthorised access" to three outside organisations 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, known as Claude, improperly accessed the systems of three organisations, which they did not name.
Unlike the incident involving OpenAI's technology, Anthropic's models had access to the internet "due to a misunderstanding between us and our evaluation partner," called Irregular, Anthropic said in a post.
Nonetheless, Claude used "basic techniques, such as exploiting weak passwords and unauthenticated endpoints," the blog continued.
