## Archived text

> We’ve trained Claude to flag potential misuse in conversations, a technique we call self-assessment. Right after it responds, Claude gives a preliminary safety assessment of the conversation. 
>
>
>
> Since we began using self-assessment in June, it has surfaced misuse that our other safeguards weren’t designed to catch. 
>
>
>
> Because Claude has already read the conversation, self-assessment is very efficient. And unlike classifiers, which target a discrete set of harms, it draws on Claude’s own judgment, so it gets more accurate as our models improve.
