The users can easily apply static, dynamic and aware-training quantization approaches while giving an expected accuracy criteria. It also supports different weight pruning techniques enabling the creation of pruned model giving a predefined sparsity target.

It is supplied with a set of tools to optimize your models with compression techniques such as quantization, pruning and knowledge distillation.

+# Inference
+
+Optimum Intel can be used to load models from the [Hub](https://huggingface.co/models) and create pipelines to run inference with IPEX optimizations (including patching with custom operators, weight prepacking and graph mode) on a variety of Intel processors. For now support is only enabled for CPUs.
+
+
+## Loading
+
+You can load your model and apply IPEX optimizations (including weight prepacking and graph mode). For supported architectures like LLaMA, BERT and ViT, further optimizations will be applied by patching the model to use custom operators.
+For now, support is only enabled for CPUs and the original model will be exported via TorchScript. In the future `torch.compile` will be used and model exported via TorchScript will get deprecated.
+
+```diff
+  import torch
+  from transformers import AutoTokenizer, pipeline
+- from transformers import AutoModelForCausalLM
++ from optimum.intel import IPEXModelForCausalLM
+
+  model_id = "gpt2"
+- model = AutoModelForCausalLM.from_pretrained(model_id, torch_dtype=torch.bfloat16)
++ model = IPEXModelForCausalLM.from_pretrained(model_id, torch_dtype=torch.bfloat16, export=True)
+  tokenizer = AutoTokenizer.from_pretrained(model_id)
+  pipe = pipeline("text-generation", model=model, tokenizer=tokenizer)
+  results = pipe("He's a dreadful magician and")
+```
+
+As shown in the table below, each task is associated with a class enabling to automatically load your model.
+
+| Auto Class                           | Task                                 |
