# Native Format
|
|
|
|
You may also convert Hugging Face *Transformers* models into native INT4 format for maximum performance as follows.
|
|
|
|
> [!NOTE]
|
|
> Currently only llama/bloom/gptneox/starcoder/chatglm model families are supported; you may use the corresponding API to load the converted model. (For other models, you can use the Hugging Face ``transformers`` format as described [here](./hugging_face_format.md))
|
|
|
|
|
|
```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)
|
|
```
