路由器和代理
路由器和代理允许您通过单一 API 和凭证访问来自多个提供商的模型。 它们可以简化计费，让您在不更改集成的情况下切换模型，并提供自动回退等功能。| 提供商 | Integration | 描述 |
|---|---|---|
| OpenRouter | ChatOpenRouter | 统一访问来自 OpenAI, Anthropic, Google, Meta, and more |
| LiteLLM | ChatLiteLLM | 统一接口，支持 OpenAI, Anthropic, Azure, Hugging Face, and more ，提供路由和回退功能 |
聊天补全 API
某些模型提供商提供与 OpenAI 兼容的端点，即 Chat Completions API. 在这种情况下，您可以使用ChatOpenAI 并配合自定义的 base_url 来连接这些端点以实现基本的聊天功能。
