Granite Guardian 4.1 8B

Granite Guardian 4.1 8B is a language model that judges prompts and responses. Built from Granite 4.1 8B, it handles predefined risk categories and custom criteria written in natural language.

Model design and capabilities

Its checks include jailbreaks, profanity, grounded answers and tool-call hallucinations. Custom criteria can cover formatting, length and domain requirements. It produces judgments for another application's content; it is not the general assistant that generates that content.Granite Guardian 4.1 8B model card

Practical use

Practical guidance. Calibrate each criterion on real acceptable and unacceptable examples. Track false positives and missed violations separately. Use ordinary code for exact rules such as required fields where possible, and reserve the model judge for decisions that need language interpretation.
