Anthropic Works on a Name Tag That Requires Cryptography

Anthropic is developing FlashProve, an open source system intended to verify which AI model produced a particular output. The proposed tool uses cryptographic proof for what researchers call provable inference, allowing a user to check whether an answer came from the model it claims to come from. The idea resembles a cryptographic signature on an email, where a recipient can check a claimed source. Here, the aim is to make it harder for an impostor model to pass its output off as that of another system. Anthropic described the work in a blog post; it remains a system the company is working on, rather than a guarantee already available for every AI response. The distinction matters when different models are sold or presented under different names. A user may care which system generated an answer, and a label on its own depends on trusting whoever attached it. A proof would offer a way to check that claim mathematically. Of course, confirming the name on the badge would not turn every answer into a correct one. It would establish who produced the response, not whether the response deserves a gold star. After years of assistants introducing themselves with great confidence, the industry is working on the less glamorous part of introductions: showing identification.
