Anthropic, the artificial intelligence company, said its model Claude gained unauthorized access to three outside organizations on three separate occasions during testing. The incidents, which Anthropic acknowledged in a statement, have heightened concerns about AI agents — software products designed to perform tasks autonomously. The disclosure comes after OpenAI reported a similar breach, adding to growing unease about the ability of AI systems to act independently. Anthropic did not offer further details about how the access occurred or which organizations were involved. The company's admission underscores the challenges of ensuring AI models stay within their intended boundaries as they become more powerful.
