-- Large Language Model (LLM) optimization:
-Intel® Extension for PyTorch\* provides a new dedicated module, ipex.llm, to host for Large Language Models (LLMs) specific APIs. With ipex.llm, Intel® Extension for PyTorch\* provides comprehensive LLM optimization cross various popular datatypes including FP32/BF16/INT8/INT4. Specifically for low precision, both SmoothQuant and Weight-Only quantization are supported for various scenarios. And user can also run Intel® Extension for PyTorch\* with Tensor Parallel to fit in the multiple ranks or multiple nodes scenarios to get even better performance.
-
-  A typical API under this new module is ipex.llm.optimize, which is designed to optimize transformer-based models within frontend Python modules, with a particular focus on Large Language Models (LLMs). It provides optimizations for both model-wise and content-generation-wise. ipex.llm.optimize is an upgrade API to replace previous ipex.optimize_transformers, which will bring you more consistent LLM experience and performance. Below shows a simple example of ipex.llm.optimize for fp32 or bf16 inference:
-
-  ```python
-  import torch
-  import intel_extension_for_pytorch as ipex
-  import transformers
-
-  model= transformers.AutoModelForCausalLM(model_name_or_path).eval()
-
-  dtype = torch.float # or torch.bfloat16
-  model = ipex.llm.optimize(model, dtype=dtype)
-
-  model.generate(YOUR_GENERATION_PARAMS)
-  ```
-
-  More examples of this API can be found at LLM optimization API.
-
-  Besides the new optimization API for LLM inference, Intel® Extension for PyTorch\* also provides new capability for users to auto-tune a good quantization recipe for running SmoothQuant INT8 with good accuracy. SmoothQuant is a popular method to improve the accuracy of int8 quantization. The new auto-tune API allows automatic global alpha tuning, and automatic layer-by-layer alpha tuning provided by Intel® Neural Compressor for the best INT8 accuracy. More details can be found at SmoothQuant Recipe Tuning API introduction.
-
-  Intel® Extension for PyTorch\* newly optimized many more LLM models including more llama2 variance like llama2-13b/llama2-70b, encoder-decoder model like T5, code generation models like starcoder/codegen, and more like Baichuan, Baichuan2, ChatGLM2, ChatGLM3, mistral, mpt, dolly, etc.. A full list of optimized models can be found at LLM optimization.
