Set the values a workflow exposes without editing the ComfyUI graph for every run.
Before you start #
Select a Pipe in Prompt Studio. Its editor defines which graph inputs are visible, how they are labeled, and whether they belong in Core or Expanded.
The Pipe configurator is generated from the active Pipe schema. It can present prompts, numbers, choices, toggles, models, and media inputs with creator-facing labels and ordering. Core holds the controls needed most often; Expanded keeps deliberate variation available without crowding the main path.
Work from Core outward #
- Read the Pipe description and readiness state.
- Set required Core values.
- Open Expanded for a control you intend to change.
- Use Reset when you want the Pipe’s saved default, not a guessed value.
- Generate one result before tuning several dimensions.
Runtime-backed choices, such as models or node-defined options, come from the connected ComfyUI engine. Revalidate the Pipe when those lists disagree with the engine you are using.
Field behavior #
| Control | Typical use |
|---|---|
| Text | Positive prompts, negative prompts, captions, names |
| Number | Seed, steps, strength, dimensions, frame count |
| Choice | Sampler, scheduler, model, node-defined option |
| Toggle | Workflow branch or standard bypass |
| Media | Image, video, mask, or another supported input |
What Studio changes #
The visible form writes values into mapped graph inputs at submission. It preserves graph connections and ordinary workflow defaults that are not intentionally exposed or changed.
If a useful control is missing #
Open Edit Pipe controls to expose, label, group, or reorder the mapped input. Use Install Missing Models and Nodes when the control exists but its runtime choices cannot resolve.
