Note

This repository contains models that have been converted to the GGUF format with various quantizations from an IBM Granite base model.

Model Summary: Granite Guardian 3.3 8b is a specialized Granite 3.3 8B model designed to judge if the input prompts and the output responses of an LLM based system meet specified criteria. The model comes pre-baked with certain criteria including but not limited to: jailbreak attempts, profanity, and hallucinations related to tool calls and retrieval augmented generation in agent-based systems. Additionally, the model also allows users to bring their own criteria and tailor the judging behavior to specific use-cases.

This version of Granite Guardian is a hybrid thinking model that allows the user to operate in thinking or non-thinking model. In thinking mode, the model produces detailed reasoning traces though <think> ... </think> and <score> ... </score> tags. In non-thinking mode, the model only produces the judgement score though the <score> ... </score> tags.

It is trained on unique data comprising human annotations and synthetic data informed by internal red-teaming. It outperforms other open-source models in the same space on standard benchmarks.
