The rule

A server-side sanitizer must run on every AI model response.

The sanitizer detects and removes unwanted content. This ensures the output follows all rules and is clean.

A server-side sanitizer checks every response from an AI model. It uses special patterns to find unwanted text. These patterns look for things like brand names or parts of the AI's internal rules. The sanitizer removes these unwanted parts. It also removes extra formatting like bold text markers. If the response is too short after cleaning, it means only unwanted text was present. In that case, the sanitizer returns an empty response.

An AI model generates a product description. The description accidentally includes a brand name and some internal instructions. The server-side sanitizer runs. It finds and removes the brand name. It also removes the internal instructions. The user receives a clean product description without errors.
