### 针对 VLLM 框架的 TeleCoder3 模型补丁
|
| 2 |
-
|
| 3 |
-
#### 目前支持以下功能
|
| 4 |
-
- 工具调用解析
|
| 5 |
-
- 支持 Interleaved Thinking 模式:chat 接口的 message 支持 reasoning_content 字段,并拼接到 模型上下文中
|
| 6 |
-
|
| 7 |
-
#### 使用教程
|
| 8 |
-
1. 安装插件(只需要执行一次)
|
| 9 |
-
```shell
|
| 10 |
-
pip install -e .
|
| 11 |
-
```
|
| 12 |
-
2. 如果需要工具解析,启动vllm服务的时候加上参数`--enable-auto-tool-choice --tool-call-parser telechat3`
