+- We provide the downloading links of tuned static quantization qconfig summary files with good quality: ["meta-llama/Llama-2-7b-hf"](https://intel-extension-for-pytorch.s3.amazonaws.com/miscellaneous/llm/llama-2-7b_qconfig.json), ["meta-llama/Llama-2-7b-chat-hf"](https://intel-extension-for-pytorch.s3.amazonaws.com/miscellaneous/llm/llama-2-7b-chat_qconfig.json), ["meta-llama/Llama-2-13b-hf"](https://intel-extension-for-pytorch.s3.amazonaws.com/miscellaneous/llm/llama-2-13b_qconfig.json) and ["EleutherAI/gpt-j-6b"](https://intel-extension-for-pytorch.s3.amazonaws.com/miscellaneous/llm/gpt-j-6b_qconfig.json).
+- For other models' qconfig recipes, you can just try to run your model_id and use IPEX default recipes by removing "--qconfig-summary-file <path to specific model qconfig>". If IPEX default recipes are not good enough for accuracy requirements, please refer to the [Intel® Neural Compressor tutorial](https://github.com/intel/neural-compressor/blob/master/docs/source/smooth_quant.md#validated-models) for more tuned recipes.

 *Notes for all quantizations:*
 
-(1) <a name="generation_sq">for all quantization benchmarks</a>, the first runs will auto-generate the quantized model named "best_model.pt" in the "--output-dir" path, you can reuse these quantized models for inference-only benchmarks by adding "--quantized-model-path <output_dir + "best_model.pt">". Specific for static quantization, if not using "--qconfig-summary-file", a qconfig recipe will also been generated in the "--output-dir" path.
