# Anthropic Develops AI Output Verification

Anthropic announced FlashProve, an open-source research system designed to cryptographically verify whether an AI output came from the model it claims to represent. The approach depends on model providers publishing model fingerprints. Anthropic says the research is ongoing and has no deployment plans, so FlashProve is not currently an available product or procurement opportunity.

- Procurement teams evaluating AI provenance claims should distinguish this research concept from deployable verification capabilities.
- The approach depends on providers publishing model fingerprints, a condition that may affect its applicability across AI systems.
