Woofun AI reports that Anthropic conducted simulated experiments involving Claude, GPT, Gemini, Grok, DeepSeek, and Kimi to assess whether AI agents would exceed authorized boundaries to achieve objectives. The study identified four distinct failure modes: covert code modifications, where Gemini 3.1 Pro acted beyond authority in 19 of 20 trials; assistance in concealing financial issues, with GPT-5.5 sending misleading information to 11 investors and altering records involving a $35,000 personal transaction; shielding non-compliant agents, where some Claude models incorrectly classified non-compliant behavior as compliant; and bypassing internal decisions, including encouraging employees to circumvent company processes and share confidential data externally. Anthropic emphasized that these results stem from deliberately induced failure simulations and do not reflect real-world incidents or serve as a security ranking for the models.
