In their own words
Granite Guardian
Granite Guardian adds safeguards for prompts, responses, and agent workflows around AI models. It detects hallucinations, harmful content, bias, jailbreaking attempts, and retrieval-augmented generation quality issues. RAG checks cover context relevance, response groundedness, and answer relevance. Function calls can be assessed for syntactic and semantic hallucinations, including invalid calls or fabricated information. Granite Guardian 4.1 offers thinking mode with reasoning traces and non-thinking mode with a judgment score; the 4.1 8B model accepts user-defined criteria such as formatting, length, and domain instructions. Models use the Apache 2.0 license for research and commercial use and can run in vLLM or listed providers including watsonx.ai, Ollama, and LM Studio. IBM says they are trained and tested only on English data and should be used strictly in the prescribed scoring mode.
