Anthropic open-sources FlashProve to prove which AI model wrote an answer

Share

FlashProve is an early attempt to cryptographically prove which model generated a response—aimed at stopping silent model swaps and mislabeling. For enterprises and regulators, this is the kind of provenance primitive you’ll eventually want in contracts and audits: 'show me the proof this came from the model and version we agreed to pay for and certify.'
