Anthropic is working on a system to prove AI models’ identity

Anthropic is developing a system called FlashProve that would let anyone verify that an AI response genuinely came from the model it claims to have produced it. The identity-proof mechanism is aimed at a growing problem in AI deployment: distinguishing authentic outputs from those generated by impostor or mislabeled models. The effort matters because businesses increasingly route critical workflows through third-party AI services and need a reliable way to confirm which model actually handled a request. Details on the number of models supported, performance overhead, and a release timeline were not disclosed. Watch for Anthropic to publish technical details or open the system to outside developers, and for rival AI labs to respond with competing verification standards.
