## IPEX-LLM
|
||||
**[`ipex-llm`](https://ipex-llm.readthedocs.io/en/latest/doc/LLM/index.html)** is a library for running **LLM** (large language model) on Intel **XPU** (from *Laptop* to *GPU* to *Cloud*) using **INT4** with very low latency[^1] (for any **PyTorch** model).
|
||||
|
||||
> *It is built on top of the excellent work of [llama.cpp](https://github.com/ggerganov/llama.cpp), [gptq](https://github.com/IST-DASLab/gptq), [ggml](https://github.com/ggerganov/ggml), [llama-cpp-python](https://github.com/abetlen/llama-cpp-python), [bitsandbytes](https://github.com/TimDettmers/bitsandbytes), [qlora](https://github.com/artidoro/qlora), [gptq_for_llama](https://github.com/qwopqwop200/GPTQ-for-LLaMa), [chatglm.cpp](https://github.com/li-plus/chatglm.cpp), [redpajama.cpp](https://github.com/togethercomputer/redpajama.cpp), [gptneox.cpp](https://github.com/byroneverson/gptneox.cpp), [bloomz.cpp](https://github.com/NouamaneTazi/bloomz.cpp/), etc.*

|
||||
|
||||
#### Run Model
|
||||
|
||||
You may run the models using **`ipex-llm`** through one of the following APIs:
|
||||
1. [Hugging Face `transformers` API](#1-hugging-face-transformers-api)
|
||||
2. [Native INT4 Model](#2-native-int4-model)
|
||||
3. [LangChain API](#3-langchain-api)
|
||||
4. [CLI (command line interface) Tool](#4-cli-tool)
|
||||
|
||||
##### 1. Hugging Face `transformers` API
|
||||
You may run any Hugging Face *Transformers* model as follows:
|
||||
|
||||
###### CPU INT4
|
||||
You may apply INT4 optimizations to any Hugging Face *Transformers* model on Intel CPU as follows.
|
||||
|
||||
```python
|
||||
#load Hugging Face Transformers model with INT4 optimizations
|
||||
from ipex_llm.transformers import AutoModelForCausalLM
|
||||
model = AutoModelForCausalLM.from_pretrained('/path/to/model/', load_in_4bit=True)
|
||||
|
||||
#run the optimized model on Intel CPU
|
||||
from transformers import AutoTokenizer
|
||||
tokenizer = AutoTokenizer.from_pretrained(model_path)
|
||||
input_ids = tokenizer.encode(input_str, ...)
|
||||
output_ids = model.generate(input_ids, ...)
|
||||
output = tokenizer.batch_decode(output_ids)
|
||||
```
|
||||
|
||||
See the complete examples [here](example/CPU/HF-Transformers-AutoModels/Model/).
|
||||
|
||||
###### GPU INT4
|
||||
You may apply INT4 optimizations to any Hugging Face *Transformers* model on Intel GPU as follows.
|
||||
|
||||
```python
|
||||
#load Hugging Face Transformers model with INT4 optimizations
|
||||
from ipex_llm.transformers import AutoModelForCausalLM
|
||||
import intel_extension_for_pytorch
|
||||
model = AutoModelForCausalLM.from_pretrained('/path/to/model/', load_in_4bit=True)
|
||||
|
||||
#run the optimized model on Intel GPU
|
||||
model = model.to('xpu')
|
||||
|
||||
from transformers import AutoTokenizer
|
||||
tokenizer = AutoTokenizer.from_pretrained(model_path)
|
||||
input_ids = tokenizer.encode(input_str, ...).to('xpu')
|
||||
output_ids = model.generate(input_ids, ...)
|
||||
output = tokenizer.batch_decode(output_ids.cpu())
|
||||
```
|
||||
See the complete examples [here](example/GPU).
|
||||
|
||||
###### More Low-Bit Support
|
||||
- Save and load
|
||||
|
||||
After the model is optimized using `ipex-llm`, you may save and load the model as follows:
|
||||
```python
|
||||
model.save_low_bit(model_path)
|
||||
new_model = AutoModelForCausalLM.load_low_bit(model_path)
|
||||
```
|
||||
*See the complete example [here](example/CPU/HF-Transformers-AutoModels/Save-Load).*
|
||||
|
||||
- Additonal data types
|
||||
|
||||
In addition to INT4, You may apply other low bit optimizations (such as *INT8*, *INT5*, *NF4*, etc.) as follows:
|
||||
|
||||
```python
|
||||
model = AutoModelForCausalLM.from_pretrained('/path/to/model/', load_in_low_bit="sym_int8")
|
||||
```
|
||||
*See the complete example [here](example/CPU/HF-Transformers-AutoModels/More-Data-Types).*
|
||||
|
||||
##### 2. Native INT4 model
|
||||
|
||||
You may also convert Hugging Face *Transformers* models into native INT4 model format for maximum performance as follows.
|
||||
|
||||
>**Notes**: Currently only llama/bloom/gptneox/starcoder/chatglm model families are supported; for other models, you may use the Hugging Face `transformers` model format as described above).
|
||||
|
||||
```python
|
||||
#convert the model
|
||||
from ipex_llm import llm_convert
|
||||
ipex_llm_path = llm_convert(model='/path/to/model/',
|
||||
outfile='/path/to/output/', outtype='int4', model_family="llama")
|
||||
|
||||
#load the converted model
|
||||
#switch to ChatGLMForCausalLM/GptneoxForCausalLM/BloomForCausalLM/StarcoderForCausalLM to load other models
|
||||
from ipex_llm.transformers import LlamaForCausalLM
|
||||
llm = LlamaForCausalLM.from_pretrained("/path/to/output/model.bin", native=True, ...)
|
||||
|
||||
#run the converted model
|
||||
input_ids = llm.tokenize(prompt)
|
||||
output_ids = llm.generate(input_ids, ...)
|
||||
output = llm.batch_decode(output_ids)
|
||||
```
|
||||
|
||||
See the complete example [here](example/CPU/Native-Models/native_int4_pipeline.py).
|
||||
|
||||
##### 3. LangChain API
|
||||
You may run the models using the LangChain API in `ipex-llm`.
|
||||
|
||||
- **Using Hugging Face `transformers` model**
|
||||
|
||||
You may run any Hugging Face *Transformers* model (with INT4 optimiztions applied) using the LangChain API as follows:
|
||||
|
||||
```python
|
||||
from ipex_llm.langchain.llms import TransformersLLM
|
||||
from ipex_llm.langchain.embeddings import TransformersEmbeddings
|
||||
from langchain.chains.question_answering import load_qa_chain
|
||||
|
||||
embeddings = TransformersEmbeddings.from_model_id(model_id=model_path)
|
||||
ipex_llm = TransformersLLM.from_model_id(model_id=model_path, ...)
|
||||
|
||||
doc_chain = load_qa_chain(ipex_llm, ...)
|
||||
output = doc_chain.run(...)
|
||||
```
|
||||
See the examples [here](example/CPU/LangChain/transformers_int4).
|
||||
|
||||
- **Using native INT4 model**
|
||||
|
||||
You may also convert Hugging Face *Transformers* models into *native INT4* format, and then run the converted models using the LangChain API as follows.
|
||||
|
||||
>**Notes**:* Currently only llama/bloom/gptneox/starcoder/chatglm model families are supported; for other models, you may use the Hugging Face `transformers` model format as described above).
|
||||
|
||||
```python
|
||||
from ipex_llm.langchain.llms import LlamaLLM
|
||||
from ipex_llm.langchain.embeddings import LlamaEmbeddings
|
||||
from langchain.chains.question_answering import load_qa_chain
|
||||
|
||||
#switch to ChatGLMEmbeddings/GptneoxEmbeddings/BloomEmbeddings/StarcoderEmbeddings to load other models
|
||||
embeddings = LlamaEmbeddings(model_path='/path/to/converted/model.bin')
|
||||
#switch to ChatGLMLLM/GptneoxLLM/BloomLLM/StarcoderLLM to load other models
|
||||
ipex_llm = LlamaLLM(model_path='/path/to/converted/model.bin')
|
||||
|
||||
doc_chain = load_qa_chain(ipex_llm, ...)
|
||||
doc_chain.run(...)
|
||||
```
|
||||
|
||||
See the examples [here](example/CPU/LangChain/native_int4).

##### 4. CLI Tool
|
||||
>**Note**: Currently `ipex-llm` CLI supports *LLaMA* (e.g., *vicuna*), *GPT-NeoX* (e.g., *redpajama*), *BLOOM* (e.g., *pheonix*) and *GPT2* (e.g., *starcoder*) model architecture; for other models, you may use the Hugging Face `transformers` or LangChain APIs.
|
||||
|
||||
- ##### Convert model
|
||||
|
||||
You may convert the downloaded model into native INT4 format using `llm-convert`.
|
||||
|
||||
```bash
|
||||
#convert PyTorch (fp16 or fp32) model;
|
||||
#llama/bloom/gptneox/starcoder model family is currently supported
|
||||
llm-convert "/path/to/model/" --model-format pth --model-family "bloom" --outfile "/path/to/output/"
|
||||
|
||||
#convert GPTQ-4bit model
|
||||
#only llama model family is currently supported
|
||||
llm-convert "/path/to/model/" --model-format gptq --model-family "llama" --outfile "/path/to/output/"
|
||||
```
|
||||
|
||||
- ##### Run model
|
||||
|
||||
You may run the converted model using `llm-cli` or `llm-chat` (*built on top of `main.cpp` in [llama.cpp](https://github.com/ggerganov/llama.cpp)*)
|
||||
|
||||
```bash
|
||||
#help
|
||||
#llama/bloom/gptneox/starcoder model family is currently supported
|
||||
llm-cli -x gptneox -h
|
||||
|
||||
#text completion
|
||||
#llama/bloom/gptneox/starcoder model family is currently supported
|
||||
llm-cli -t 16 -x gptneox -m "/path/to/output/model.bin" -p 'Once upon a time,'
|
||||
|
||||
#chat mode
|
||||
#llama/gptneox model family is currently supported
|
||||
llm-chat -m "/path/to/output/model.bin" -x llama
|
||||
```
|
