##  Introduction

XTuner is an efficient, flexible and full-featured toolkit for fine-tuning large models.

**Efficient**

- Support LLM, VLM pre-training / fine-tuning on almost all GPUs. XTuner is capable of fine-tuning 7B LLM on a single 8GB GPU, as well as multi-node fine-tuning of models exceeding 70B.
- Automatically dispatch high-performance operators such as FlashAttention and Triton kernels to increase training throughput.
- Compatible with [DeepSpeed](https://github.com/microsoft/DeepSpeed) , easily utilizing a variety of ZeRO optimization techniques.

**Flexible**

- Support various LLMs ([InternLM](https://huggingface.co/internlm), [Mixtral-8x7B](https://huggingface.co/mistralai), [Llama 2](https://huggingface.co/meta-llama), [ChatGLM](https://huggingface.co/THUDM), [Qwen](https://huggingface.co/Qwen), [Baichuan](https://huggingface.co/baichuan-inc), ...).
- Support VLM ([LLaVA](https://github.com/haotian-liu/LLaVA)). The performance of [LLaVA-InternLM2-20B](https://huggingface.co/xtuner/llava-internlm2-20b) is outstanding.
- Well-designed data pipeline, accommodating datasets in any format, including but not limited to open-source and custom formats.
- Support various training algorithms ([QLoRA](http://arxiv.org/abs/2305.14314), [LoRA](http://arxiv.org/abs/2106.09685), full-parameter fune-tune), allowing users to choose the most suitable solution for their requirements.

**Full-featured**

- Support continuous pre-training, instruction fine-tuning, and agent fine-tuning.
- Support chatting with large models with pre-defined templates.
- The output models can seamlessly integrate with deployment and server toolkit ([LMDeploy](https://github.com/InternLM/lmdeploy)), and large-scale evaluation toolkit ([OpenCompass](https://github.com/open-compass/opencompass), [VLMEvalKit](https://github.com/open-compass/VLMEvalKit)).

##  Quick Start

### Installation

- It is recommended to build a Python-3.10 virtual environment using conda

  ```bash
  conda create --name xtuner-env python=3.10 -y
  conda activate xtuner-env
  ```

- Install XTuner via pip

  ```shell
  pip install -U xtuner
  ```

  or with DeepSpeed integration

  ```shell
  pip install -U 'xtuner[deepspeed]'
  ```

- Install XTuner from source

  ```shell
  git clone https://github.com/InternLM/xtuner.git
  cd xtuner
  pip install -e '.[all]'
  ```

### Fine-tune

XTuner supports the efficient fine-tune (*e.g.*, QLoRA) for LLMs. Dataset prepare guides can be found on [dataset_prepare.md](./docs/en/user_guides/dataset_prepare.md).

- **Step 0**, prepare the config. XTuner provides many ready-to-use configs and we can view all configs by

  ```shell
  xtuner list-cfg
  ```

  Or, if the provided configs cannot meet the requirements, please copy the provided config to the specified directory and make specific modifications by

  ```shell
  xtuner copy-cfg ${CONFIG_NAME} ${SAVE_PATH}
  vi ${SAVE_PATH}/${CONFIG_NAME}_copy.py
  ```

- **Step 1**, start fine-tuning.

  ```shell
  xtuner train ${CONFIG_NAME_OR_PATH}
  ```

  For example, we can start the QLoRA fine-tuning of InternLM2.5-Chat-7B with oasst1 dataset by

  ```shell
  # On a single GPU
  xtuner train internlm2_5_chat_7b_qlora_oasst1_e3 --deepspeed deepspeed_zero2
  # On multiple GPUs
  (DIST) NPROC_PER_NODE=${GPU_NUM} xtuner train internlm2_5_chat_7b_qlora_oasst1_e3 --deepspeed deepspeed_zero2
  (SLURM) srun ${SRUN_ARGS} xtuner train internlm2_5_chat_7b_qlora_oasst1_e3 --launcher slurm --deepspeed deepspeed_zero2
  ```

  - `--deepspeed` means using [DeepSpeed](https://github.com/microsoft/DeepSpeed)  to optimize the training. XTuner comes with several integrated strategies including ZeRO-1, ZeRO-2, and ZeRO-3. If you wish to disable this feature, simply remove this argument.

  - For more examples, please see [finetune.md](./docs/en/user_guides/finetune.md).

- **Step 2**, convert the saved PTH model (if using DeepSpeed, it will be a directory) to Hugging Face model, by

  ```shell
  xtuner convert pth_to_hf ${CONFIG_NAME_OR_PATH} ${PTH} ${SAVE_PATH}
  ```

### Chat

XTuner provides tools to chat with pretrained / fine-tuned LLMs.

```shell
xtuner chat ${NAME_OR_PATH_TO_LLM} --adapter {NAME_OR_PATH_TO_ADAPTER} [optional arguments]
```

For example, we can start the chat with InternLM2.5-Chat-7B :

```shell
xtuner chat internlm/internlm2_5-chat-7b --prompt-template internlm2_chat
```

For more examples, please see [chat.md](./docs/en/user_guides/chat.md).

### Deployment

- **Step 0**, merge the Hugging Face adapter to pretrained LLM, by

  ```shell
  xtuner convert merge \
      ${NAME_OR_PATH_TO_LLM} \
      ${NAME_OR_PATH_TO_ADAPTER} \
      ${SAVE_PATH} \
      --max-shard-size 2GB
  ```

- **Step 1**, deploy fine-tuned LLM with any other framework, such as [LMDeploy](https://github.com/InternLM/lmdeploy) .

  ```shell
  pip install lmdeploy
  python -m lmdeploy.pytorch.chat ${NAME_OR_PATH_TO_LLM} \
      --max_new_tokens 256 \
      --temperture 0.8 \
      --top_p 0.95 \
      --seed 0
  ```

   Seeking efficient inference with less GPU memory? Try 4-bit quantization from [LMDeploy](https://github.com/InternLM/lmdeploy)! For more details, see [here](https://github.com/InternLM/lmdeploy/tree/main#quantization).

### Evaluation

- We recommend using [OpenCompass](https://github.com/InternLM/opencompass), a comprehensive and systematic LLM evaluation library, which currently supports 50+ datasets with about 300,000 questions.
