Announcement
Anthropic releases FlashProve, an open-source prototype for verifying AI model responses
FlashProve uses cryptographic proofs to check which model produced a response without exposing its weights, Anthropic says.
TLDR
The research release includes code and a technical report. Anthropic says generating proofs for a 4-bit-quantized Llama 4 Maverick used roughly 70–95 times the GPU time of running the model on vLLM. One commentator questioned whether that overhead would hold against a more optimized baseline.
