+## Llama-2-70b-chat-hf-2bit_g16_s128-HQQ
+This is a version of the LLama-2-70B-chat-hf model quantized to 2-bit via Half-Quadratic Quantization (HQQ): https://mobiusml.github.io/hqq_blog/
+
+To run the model, install the HQQ library from https://github.com/mobiusml/hqq and use it as follows:
+``` Python
+from hqq.models.llama_hf import LlamaHQQ
+import transformers
+
+model_id = 'mobiuslabsgmbh/Llama-2-70b-chat-hf-2bit_g16_s128-HQQ'
+#Load the tokenizer
+tokenizer = transformers.AutoTokenizer.from_pretrained(model_id)
+#Load the model
+model = LlamaHQQ.from_quantized(model_id)
+```
+
+*Limitations*: <br>
+-Only supports single GPU runtime.<br>
+-Not compatible with HuggingFace's PEFT.<br>
