A receipt that says the model was not swapped
Anthropic open-sourced FlashProve, a research prototype that proves a reply came from a committed set of weights. It is Apache 2.0 research code, not a Claude setting. Proving costs many times a normal answer. Nice receipt. Expensive printer.
- Verdict
- Watch Promising, but something is missing: access, pricing, or proof.
- For
- researchers who want a receipt that the weights were not swapped
- Why it matters
- FlashProve is Apache 2.0 research code, not a Claude setting, and proving a reply costs many times a normal answer.
- Next check
- Recheck if Anthropic ships it as a product setting rather than a research prototype.
