By John Liu, Hadas Gold, CNN(CNN) — Anthropic’s most advanced artificial intelligence model used fake identities to deceive real people and try to plant malicious code during testing by Britain’s AI Security Institute (AISI) –– the latest example of an AI model going rogue. “This is the first time AISI has seen deception of this severity that was targeted at a real person, unprompted, in the real world,” the institute said Tuesday. But unlike these earlier reported security breaches, the British institute explicitly gave the models internet access during its testing. The institute’s disclosure came on the same day representatives from the top AI companies met with the White House to discuss the new framework where the government will review the most advanced AI models before they’re released publicly. OpenAI identified the two unsanctioned actions as crossing outside the test environment and engage in actions unrequired for the exercises.
