## 1. 安装依赖

```bash
pip install -r requirements.txt
```

## 2. 运行示例

```bash
python examples/qwen3.5_0.8b_finetune.py
```

## 3. 使用自己的数据

准备数据文件 `data.json`:

```json
[
  {
    "instruction": "你的指令",
    "input": "输入（可选）",
    "output": "期望输出"
  }
]
```

修改示例脚本中的数据集路径，然后运行。

## 4. 推理

```bash
python scripts/inference.py --model_path ./outputs/qwen3.5-0.5b-finetuned --interactive
```

## 5. API 服务

```bash
python scripts/start_api.py
```

访问 http://localhost:8000/docs 查看 API 文档。
