Document how to use StepFun's Step Plan subscription endpoint with the
existing `stepfun` provider by overriding `apiBase`, following the same
pattern as the `zhipu` provider's coding plan documentation.
- **Base URL**: `https://api.stepfun.com/step_plan/v1` (dedicated endpoint)
- **API Key**: same `STEPFUN_API_KEY` as the regular `stepfun` provider
- **Models**: `step-3.5-flash`, `step-3.5-flash-2603`, `step-router-v1`
Changes:
- `docs/configuration.md` — provider tip, and config example showing
`apiBase` override on the existing `stepfun` provider
Test: 488/488 provider tests passed.
Add APIFree as a built-in OpenAI-compatible provider. APIFree offers
agent-optimised models such as skywork-ai/skyclaw-v1 through an
OpenAI-compatible API at https://api.apifree.ai/agent/v1.
Changes:
- Register apifree provider in the provider registry
- Add config schema field
- Add documentation with configuration example
- Add provider tests, websocket channel tests, and webui tests
- Add provider icon in settings UI
- Add reasoning_content fallback from reasoning in _parse dict branch
- Add content fallback from msg.reasoning in _parse SDK object branch
- Add reasoning_content fallback in _parse SDK object branch
- Add reasoning fallback in _parse_chunks dict branch
- Add reasoning fallback in _parse_chunks SDK object branch
This ensures StepFun Plan API works correctly in both streaming and
non-streaming modes, for both dict and SDK object response formats.
Add comprehensive tests for the StepFun Plan API compatibility fix:
- _parse dict branch: content and reasoning_content fallback to reasoning
- _parse SDK object branch: same fallback for pydantic response objects
- _parse_chunks dict branch: reasoning field handled in streaming mode
- _parse_chunks SDK branch: reasoning fallback for SDK delta objects
- Precedence tests: reasoning_content field takes priority over reasoning
Refs: fix(provider): support StepFun Plan API reasoning field fallback
StepFun Plan API returns response content in the 'reasoning' field when
the model is in thinking mode and 'content' is empty. OpenAICompatProvider
previously only checked 'content' and 'reasoning_content', missing this field.
This patch adds a fallback: if content is empty and 'reasoning' is present,
extract text from reasoning to populate content, ensuring StepFun models
(step-3.5-flash, step-3.5-flash-2603) work correctly with tool calls.
