About

Granite Guardian is a family of IBM models that judge the inputs and outputs of an LLM system against given criteria. The models ship with built-in criteria such as jailbreak attempts, profanity and hallucinations in tool calls and RAG, and users can bring their own criteria. The README lists Granite-Guardian-4.1-8B, released in April 2026, and provides vLLM quickstart notebooks.

Use cases: security-scanning, llm-evaluation
