+Quantization is done by [llama.cpp](https://github.com/ggerganov/llama.cpp).
+
+## Model Summary (from original repository)
+
+**Granite Guardian 3.1 2B** is a fine-tuned Granite 3.1 2B Instruct model designed to detect risks in prompts and responses.
+It can help with risk detection along many key dimensions catalogued in the [IBM AI Risk Atlas](https://www.ibm.com/docs/en/watsonx/saas?topic=ai-risk-atlas).
+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.
