BigDL-LLM: low-Bit LLM library
************************************************

.. raw:: html

   <p>
      <a href="https://github.com/intel-analytics/BigDL/tree/main/python/llm"><code><span>bigdl-llm</span></code></a> is a library for running <strong>LLM</strong> (large language model) on Intel <strong>XPU</strong> (from <em>Laptop</em> to <em>GPU</em> to <em>Cloud</em>) using <strong>INT4</strong> with very low latency <sup><a href="#footnote-perf" id="ref-perf">[1]</a></sup> (for any <strong>PyTorch</strong> model).
   </p>

.. note::

   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>`_, `bitsandbytes <https://github.com/TimDettmers/bitsandbytes>`_, `qlora <https://github.com/artidoro/qlora>`_, etc.

============================================
Latest update
============================================
- **[New]** ``bigdl-llm`` now supports QLoRA fintuning on Intel GPU; see the the example `here <https://github.com/intel-analytics/BigDL/tree/main/python/llm/example/GPU/QLoRA-FineTuning>`_.
- ``bigdl-llm`` now supports Intel GPU (including Arc, Flex and MAX); see the the latest GPU examples `here <https://github.com/intel-analytics/BigDL/tree/main/python/llm/example/GPU>`_.
- ``bigdl-llm`` tutorial is released `here <https://github.com/intel-analytics/bigdl-llm-tutorial>`_.
- Over 20 models have been verified on ``bigdl-llm``, including *LLaMA/LLaMA2, ChatGLM/ChatGLM2, MPT, Falcon, Dolly, StarCoder, Whisper, InternLM, QWen, Baichuan, Aquila, MOSS* and more; see the complete list `here <https://github.com/intel-analytics/bigdl#verified-models>`_.

``bigdl-llm`` quickstart
============================================

- `CPU <#cpu-quickstart>`_
- `GPU <#gpu-quickstart>`_

--------------------------------------------
CPU Quickstart
--------------------------------------------

You may install ``bigdl-llm`` on Intel CPU as follows as follows:

.. code-block:: console

   pip install --pre --upgrade bigdl-llm[all]

.. note::

   ``bigdl-llm`` has been tested on Python 3.9.

You can then apply INT4 optimizations to any Hugging Face *Transformers* models as follows.

.. code-block:: python

   #load Hugging Face Transformers model with INT4 optimizations
   from bigdl.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)

--------------------------------------------
GPU Quickstart
--------------------------------------------

You may install ``bigdl-llm`` on Intel GPU as follows as follows:

.. code-block:: console

   # below command will install intel_extension_for_pytorch==2.0.110+xpu as default
   # you can install specific ipex/torch version for your need
   pip install --pre --upgrade bigdl-llm[xpu] -f https://developer.intel.com/ipex-whl-stable-xpu

.. note::

   ``bigdl-llm`` has been tested on Python 3.9.

You can then apply INT4 optimizations to any Hugging Face *Transformers* models on Intel GPU as follows.

.. code-block:: python

   #load Hugging Face Transformers model with INT4 optimizations
   from bigdl.llm.transformers import AutoModelForCausalLM
   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())
