# StepFun
|
|
|
|
OpenClaw includes a bundled StepFun provider plugin with two provider ids:
|
|
|
|
- `stepfun` for the standard endpoint
|
|
- `stepfun-plan` for the Step Plan endpoint
|
|
|
|
<Warning>
|
|
Standard and Step Plan are **separate providers** with different endpoints and model ref prefixes (`stepfun/...` vs `stepfun-plan/...`). Use a China key with the `.com` endpoints and a global key with the `.ai` endpoints.
|
|
</Warning>
|
|
|
|

<Accordion title="Notes">
|
|
- The provider is bundled with OpenClaw, so there is no separate plugin install step.
|
|
- `step-3.5-flash-2603` is currently exposed only on `stepfun-plan`.
|
|
- A single auth flow writes region-matched profiles for both `stepfun` and `stepfun-plan`, so both surfaces can be discovered together.
|
|
- Use `openclaw models list` and `openclaw models set <provider/model>` to inspect or switch models.
