+# MPT-7B-Chat (4-bit 128g AWQ Quantized)
+[MPT-7B-Chat](https://huggingface.co/mosaicml/mpt-7b-chat) is a chatbot-like model for dialogue generation. 
+
+This model is a 4-bit 128 group size AWQ quantized model. For more information about AWQ quantization, please click [here](https://github.com/mit-han-lab/llm-awq).
+
+## Model Date
+
+July 5, 2023
+
+## Model License
+
+Please refer to original MPT model license ([link](https://huggingface.co/mosaicml/mpt-7b-chat)).
+
+Please refer to the AWQ quantization license ([link](https://github.com/llm-awq/blob/main/LICENSE)).
+
+## CUDA Version
+
+This model was successfully tested on CUDA driver v12.1 and toolkit v11.7 with Python v3.10.11. 
+
+## How to Use
+
+```bash
+git clone https://github.com/mit-han-lab/llm-awq \
+&& cd llm-awq \
+&& git checkout 71d8e68df78de6c0c817b029a568c064bf22132d \
+&& pip install -e .
+```
