## Environment Setup
```shell
git clone https://github.com/modelscope/swift.git
cd swift
pip install -e '.[llm]'

pip install vllm
```

Here we provide examples of four models (selecting smaller-sized models to facilitate experiments): qwen-vl-chat, qwen-vl, yi-vl-6b-chat, and minicpm-v-v2_5-chat. From these examples, you can identify three different types of MLLMs: a single round of dialogue can contain multiple images (or no images), a single round of dialogue can only contain one image, and the way the entire dialogue revolves around an image and the differences in deployment and invocation methods, as well as the differences between the chat and base models within MLLMs.

If you're using qwen-audio-chat, simply replace the `<img>` tag with `<audio>` based on the qwen-vl-chat example.

## qwen-vl-chat

**Server**:
```bash
# Using the original model
CUDA_VISIBLE_DEVICES=0 swift deploy --model_type qwen-vl-chat

# Using the fine-tuned LoRA
CUDA_VISIBLE_DEVICES=0 swift deploy --ckpt_dir output/qwen-vl-chat/vx-xxx/checkpoint-xxx

# Using the fine-tuned Merge LoRA model
CUDA_VISIBLE_DEVICES=0 swift deploy --ckpt_dir output/qwen-vl-chat/vx-xxx/checkpoint-xxx-merged
```

**Client**:

```bash

response: The image is a digital painting of a kitten, which is the main subject. The kitten's fur is rendered with a mix of gray, black, and white, giving it a realistic appearance. Its eyes are wide open, and the expression is one of curiosity or alertness. The background is blurred, which brings the focus entirely on the kitten. The painting style is detailed and lifelike, capturing the essence of a young feline's innocent and playful nature. The image does not convey any specific context or background story beyond the depiction of the kitten itself.
query: How was this picture generated?
response: This picture was generated using digital art techniques. The artist likely used a software program to create the image, manipulating pixels and colors to achieve the detailed and lifelike representation of the kitten. Digital art allows for a high degree of control over the final product, enabling artists to fine-tune details and create realistic textures and shading.
