-- `adapter`：模型适配器，当前支持 `openai` 和 `openrouter`。不写时默认是 `openai`。
+- `adapter`：模型适配器，当前支持 `openai`、`openrouter`、`anthropic`。不写时默认是 `openai`。
 - `model`：模型名，例如 `gpt-4o-mini`、`gpt-4.1`、`qwen/qwen3-coder:free`。
 - `api_key`：模型服务密钥。也可以通过环境变量提供。
-- `endpoint`：自定义 OpenAI-compatible base URL。对 `openrouter` 来说会作为 `base_url` 使用。
+- `endpoint`：自定义 provider base URL。对 `openrouter`/`anthropic` 来说分别映射到各自 SDK 的 `base_url`。
 - `proxy`：代理配置，支持 `http`、`https`、`no_proxy`、`use_system_proxy`、`disabled`。
 - 其他未显式声明的字段会进入 `llm.extra`，并透传给 adapter；例如可以直接写 `temperature`、`max_tokens`。
