Anthropic introduced a method called FlashProve that, building on cryptographic techniques, enables developers to prove that a given response originated from a specific large language model; the procedure is more efficient than previous open-source solutions and can help defend against chat hijacking and verify provided models. The code was released as open source, and several researchers, including Alessandro Chiesa and Rahul Dalal, contributed.
