Anthropic releases FlashProve, an open-source prototype that cryptographically verifies an AI response came from a given model, not one that a router swapped in (Anthropic)

Anthropic has released FlashProve, an open-source prototype designed to cryptographically verify the origin of AI responses. This tool ensures that an AI's output genuinely comes from the specified model, rather than a different, potentially cheaper one that might have been substituted by a router. The release aims to enhance trust and transparency in AI interactions by providing verifiable proof of model authenticity.
