# StepFun

StepFun 作为外部官方插件（`@openclaw/stepfun-provider`）提供，包含两个 provider id：

* `stepfun` 用于标准端点
* `stepfun-plan` 用于 Step Plan 端点

<Warning>
  标准版和 Step Plan 是**独立的提供方**，它们的端点和模型 ref 前缀不同（`stepfun/...` vs `stepfun-plan/...`）。`.com` 端点请使用中国密钥，`.ai` 端点请使用全球密钥。
</Warning>

## 安装插件

```bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
openclaw plugins install @openclaw/stepfun-provider
openclaw gateway restart
```

一次认证流程会为 `stepfun` 和 `stepfun-plan` 写入与区域匹配的配置文件，因此在一次初始化运行后即可同时发现这两个端点。

  <Accordion title="说明">
    * `step-3.7-flash` 通过 OpenClaw 接受文本和图像输入。StepFun 的 API 也支持视频，但这还不是 OpenClaw 中的模型输入模态。
    * Step 3.7 支持 `low`、`medium` 和 `high` 推理强度。由于该模型没有非推理模式，`/think off` 会映射为 `low`。
    * `step-3.5-flash-2603` 目前仅在 `stepfun-plan` 上公开。
    * 使用 `openclaw models list` 和 `openclaw models set <provider/model>` 来查看或切换模型。
