Anthropic open-sources FlashProve, a zkSNARK prototype for provable AI inference

This story is from 2026-11-03. It is preserved in the archive; the latest stories are on the live feed.

Anthropic's Frontier Red Team released FlashProve, an open-source (Apache 2.0) research prototype that attaches zero-knowledge proofs to AI replies, letting users verify which model generated a response. It demonstrated zkSNARK proofs for 400B Llama 4 Maverick inference at 110 tok/s on one H100.
