Anthropic releases FlashProve zkSNARK prototype proving model replies

Anthropic released FlashProve, an Apache 2.0 zkSNARK prototype that cryptographically proves a reply originated from a committed model without revealing weights. The prototype demonstrates 110 tokens/second on a single H100 GPU with 19 MB proofs for Llama 4 Maverick.

Benchmarks are the company's own; not independently verified.

Why it matters

FlashProve lets you verify model provenance; add proof verification to onboarding to meet emerging compliance expectations.
