- Anthropic released FlashProve as open-source code for cryptographically checking which model produced an AI response.
- FlashProve verifies that a response came from a specified model, directly addressing cases where a router substitutes a cheaper model.
Why it matters: Anthropic’s open-source release gives organizations using AI model routers a cryptographic way to check the selected model rather than relying only on the router’s own record. Anthropic identifies cheaper-model substitution as the concrete failure mode FlashProve is designed to address.
