Pipe 插件

Pipe 插件用于创建自定义模型集成或转换 LLM 响应,会在 OpenWebUI 的模型下拉中显示。

什么是 Pipes

Pipes 可以用于:

  • :material-api: 连接外部 AI APIGemini、Claude 等)
  • :material-robot: 创建自定义模型封装
  • :material-cog-transfer: 变换请求与响应
  • :material-middleware: 实现中间件逻辑

可用的 Pipe 插件


Pipe 工作原理

graph LR
    A[User selects Pipe as Model] --> B[Pipe receives request]
    B --> C[Transform/Route request]
    C --> D[External API / Custom Logic]
    D --> E[Return response]
    E --> F[Display to User]

pipes 方法

定义此 Pipe 提供的模型列表:

def pipes(self):
    return [
        {"id": "my-model", "name": "My Custom Model"},
        {"id": "my-model-fast", "name": "My Custom Model (Fast)"}
    ]

pipe 方法

负责处理实际请求:

def pipe(self, body: dict) -> Generator:
    # 处理请求
    messages = body.get("messages", [])
    
    # 调用外部 API 或自定义逻辑
    response = call_external_api(messages)
    
    # 返回响应(可流式)
    return response

快速安装

  1. 下载需要的 Pipe .py 文件
  2. 前往 Admin PanelSettingsFunctions
  3. 上传并配置 API Key
  4. 该 Pipe 会作为模型选项出现

        return "Response from custom pipe"
