AI Summary

Anthropic announced an open‑source tool called FlashProve that generates cryptographic proofs linking a specific AI model to its output. The system offers “provable inference,” a mathematical guarantee that a response originated from the claimed model, similar to email signature verification. Researchers say FlashProve can block impostors—including the model’s own lab—from masquerading as another model, helping prevent covert swaps of cheaper or more expensive models that could distort costs or performance metrics. The blog post detailing the project was published on Tuesday.
