Intel® Extension for Transformers is an innovative toolkit designed to accelerate GenAI/LLM everywhere with the optimal performance of Transformer-based models on various Intel platforms, including Intel Gaudi2, Intel CPU, and Intel GPU. The toolkit provides the below key features and examples:
-
Seamless user experience of model compressions on Transformer-based models by extending Hugging Face transformers APIs and leveraging Intel® Neural Compressor
-
Advanced software optimizations and unique compression-aware runtime (released with NeurIPS 2022's paper Fast Distilbert on CPUs and QuaLA-MiniLM: a Quantized Length Adaptive MiniLM, and NeurIPS 2021's paper Prune Once for All: Sparse Pre-Trained Language Models)
-
Optimized Transformer-based model packages such as Stable Diffusion, GPT-J-6B, GPT-NEOX, BLOOM-176B, T5, Flan-T5, and end-to-end workflows such as SetFit-based text classification and document level sentiment analysis (DLSA)
-
NeuralChat, a customizable chatbot framework to create your own chatbot within minutes by leveraging a rich set of plugins such as Knowledge Retrieval, Speech Interaction, Query Caching, and Security Guardrail. This framework supports Intel Gaudi2/CPU/GPU.
-
Inference of Large Language Model (LLM) in pure C/C++ with weight-only quantization kernels for Intel CPU and Intel GPU (TBD), supporting GPT-NEOX, LLAMA, MPT, FALCON, BLOOM-7B, OPT, ChatGLM2-6B, GPT-J-6B, and Dolly-v2-3B. Support AMX, VNNI, AVX512F and AVX2 instruction set. We've boosted the performance of Intel CPUs, with a particular focus on the 4th generation Intel Xeon Scalable processor, codenamed Sapphire Rapids.

Below is the sample code to create your chatbot. See more examples.
NeuralChat provides OpenAI-compatible RESTful APIs for chat, so you can use NeuralChat as a drop-in replacement for OpenAI APIs. You can start NeuralChat server either using the Shell command or Python code.
# Shell Command
neuralchat_server start --config_file ./server/config/neuralchat.yaml# Python Code
from intel_extension_for_transformers.neural_chat import NeuralChatServerExecutor
server_executor = NeuralChatServerExecutor()
server_executor(config_file="./server/config/neuralchat.yaml", log_file="./neuralchat.log")NeuralChat service can be accessible through OpenAI client library, curl commands, and requests library. See more in NeuralChat.
from intel_extension_for_transformers.neural_chat import build_chatbot
chatbot = build_chatbot()
response = chatbot.predict("Tell me about Intel Xeon Scalable Processors.")Below is the sample code to use the extended Transformers APIs. See more examples.
We encourage you to install NeuralSpeed to get the latest features (e.g., GGUF support) of LLM low-bit inference on CPUs. You may also want to use v1.3 without NeuralSpeed by following the document
from transformers import AutoTokenizer
from intel_extension_for_transformers.transformers import AutoModelForCausalLM
model_name = "Intel/neural-chat-7b-v3-1"
prompt = "Once upon a time, there existed a little girl,"
tokenizer = AutoTokenizer.from_pretrained(model_name, trust_remote_code=True)
inputs = tokenizer(prompt, return_tensors="pt").input_ids
model = AutoModelForCausalLM.from_pretrained(model_name, load_in_4bit=True)
outputs = model.generate(inputs)You can also load PyTorch Model from Modelscope

from transformers import AutoTokenizer
from intel_extension_for_transformers.transformers import AutoModelForCausalLM, GPTQConfig
# Download Hugging Face GPTQ/AWQ model or use local quantize model
model_name = "PATH_TO_MODEL" # local path to model
woq_config = GPTQConfig(bits=4) # use AwqConfig for AWQ models, and AutoRoundConfig for AutoRound models
prompt = "Once upon a time, a little girl"
tokenizer = AutoTokenizer.from_pretrained(model_name, trust_remote_code=True)
inputs = tokenizer(prompt, return_tensors="pt").input_ids

inputs = tokenizer(prompt, return_tensors="pt").input_ids.to(device_map)
model = AutoModelForCausalLM.from_pretrained(model_name, trust_remote_code=True,
device_map=device_map, load_in_4bit=True)
model = ipex.optimize_transformers(model, inplace=True, dtype=torch.float16, woq=True, device=device_map)
output = model.generate(inputs)Note: Please refer to the example and script for more details.
