# ComfyUI workflows

`txt2img_api.json` uses only built-in ComfyUI nodes. It is a connection and
round-trip baseline, not the production sprite workflow. Set Studio's Model
field to the exact checkpoint filename installed on the worker.

Validate it locally:

```powershell
sf gpu workflow-check examples\comfyui\txt2img_api.json
```

The production workflow should be exported from ComfyUI in API format and add:

- IP-Adapter/reference conditioning fed by `{{REFERENCE_0}}`;
- pose/depth ControlNet fed by `{{CONTROL_CONTROL}}`;
- an inpaint branch fed by `{{CONTROL_MASK}}`;
- low-denoise previous-frame img2img fed by `{{CONTROL_PREVIOUS}}`;
- alpha/background removal before `SaveImage` where supported.

Keep the standard SpriteForge placeholders in the appropriate node inputs, then
run `sf gpu workflow-check` again.
