## Nauti's Take

This is one of the most convincing real-world arguments for the practical value of LLMs beyond chatbots. Mozilla might have found these 22 vulnerabilities eventually through conventional means – or might not have. The uncomfortable question is what happens when the same technology sits on the other side of the table: a model that finds vulnerabilities can theoretically exploit them too. The Anthropic-Mozilla partnership is a positive signal, but the industry urgently needs clear standards around who is allowed to run such scans and under what conditions.
