 The scripts include both single instance and distributed (DeepSpeed) use cases.<br/>
 The scripts cover model generation inference with low precions cases for different models with best perf and accuracy (bf16 AMP，static quantization and weight only quantization).<br/>

 *For Falcon models from remote hub, we need to modify the config.json to use the modeling_falcon.py in transformers. Therefore, in the following scripts, we need to pass an extra configuration file like "--config-file=model_config/tiiuae_falcon-40b_config.json". This is optional for FP32/BF16 but needed for quantizations.
 
-** For GPT-NEOX/FALCON/OPT models, the accuracy recipes of static quantization INT8 are not ready thus they will be skipped in our coverage.
+** For GPT-NEOX/FALCON/OPT/CodeGen models, the accuracy recipes of static quantization INT8 are not ready thus they will be skipped in our coverage.
 
 *Note*: The above verified models (including other models in the same model family, like "codellama/CodeLlama-7b-hf" from LLAMA family) are well supported with all optimizations like indirect access KV cache, fused ROPE, and prepacked TPP Linear (fp32/bf16). For other LLM model families, we are working in progress to cover those optimizations, which will expand the model list above.
