💫 IPEX-LLM

IPEX-LLM is a PyTorch library for running LLM on Intel CPU and GPU (e.g., local PC with iGPU, discrete GPU such as Arc, Flex and Max) with very low latency[^1]. > [!NOTE] > - It is built on top of Intel Extension for PyTorch (IPEX), as well as the excellent work of llama.cpp, bitsandbytes, vLLM, qlora, AutoGPTQ, AutoAWQ, etc. > - It provides seamless integration with llama.cpp, ollama, Text-Generation-WebUI, HuggingFace transformers, HuggingFace PEFT, LangChain, LlamaIndex, DeepSpeed-AutoTP, vLLM, FastChat, HuggingFace TRL, AutoGen, ModeScope, etc. > - 50+ models have been optimized/verified on ipex-llm (including LLaMA2, Mistral, Mixtral, Gemma, LLaVA, Whisper, ChatGLM, Baichuan, Qwen, RWKV, and more); see the complete list here.

ipex-llm Demo

See the demo of running Text-Generation-WebUI, local RAG using LangChain-Chatchat, llama.cpp and Ollama (on either Intel Core Ultra laptop or Arc GPU) with ipex-llm below.

Latest Update 🔥

• [2024/04] You can now run Llama 3 on Intel GPU using llama.cpp and ollama; see the quickstart here.
• [2024/04] ipex-llm now supports Llama 3 on both Intel GPU and CPU.
• [2024/04] ipex-llm now provides C++ interface, which can be used as an accelerated backend for running llama.cpp and ollama on Intel GPU.
• [2024/03] bigdl-llm has now become ipex-llm (see the migration guide here); you may find the original BigDL project here.
• [2024/02] ipex-llm now supports directly loading model from ModelScope (魔搭).
• [2024/02] ipex-llm added initial INT2 support (based on llama.cpp IQ2 mechanism), which makes it possible to run large-size LLM (e.g., Mixtral-8x7B) on Intel GPU with 16GB VRAM.
• [2024/02] Users can now use ipex-llm through Text-Generation-WebUI GUI.
• [2024/02] ipex-llm now supports Self-Speculative Decoding, which in practice brings ~30% speedup for FP16 and BF16 inference latency on Intel GPU and CPU respectively.
• [2024/02] ipex-llm now supports a comprehensive list of LLM finetuning on Intel GPU (including LoRA, QLoRA, DPO, QA-LoRA and ReLoRA).
• [2024/01] Using ipex-llm QLoRA, we managed to finetune LLaMA2-7B in 21 minutes and LLaMA2-70B in 3.14 hours on 8 Intel Max 1550 GPU for Standford-Alpaca (see the blog here).
