Inputs
The inbound handles are derived from the selected model, so the exact set changes per model. The two you’ll always work with are the prompt and the model selector; reference-image and parameter handles appear when the model supports them.Inputs are on the left. File/reference handles accept several edges at once; single-value handles take one. Standard connection rules still apply.
Outputs
One model call that returns several variations usually produces one output item with several image parts.
If the Image Gen node receives multiple input items from a Batch or structured list, it runs once per item and produces separate output items.
Settings
The panel mirrors the model you choose:- Model — a selector limited to models that output images. Switching models remaps the parameter fields and handles; compatible values you’d already set are carried over.
- Prompt — the primary text field for the selected model. Type
{{variable}}tokens to expose per-variable input handles for templating. - Reference images / files — file pickers for any image or file parameters the model supports, so you can set them directly on the node or connect them.
- Model parameters — the remaining exposed settings (such as count, size, or aspect ratio) render as their native controls. Less-common ones are tucked under a collapsible Advanced Settings section.
Only the controls the chosen model actually exposes appear. There is no fixed parameter list — a minimal model shows just a prompt, while a richer one adds size, count, and reference inputs.
When to use
Reach for Image Gen whenever a step should produce a picture — generating art or product shots from a description, or editing/restyling an incoming image when the model accepts a reference. Pick the model that fits your quality, speed, and cost needs.Connects to
- Upstream: a User Input feeding the prompt, model, or a reference image; an LLM node producing a refined prompt; any node emitting an
image/filefor the reference handle. - Downstream: a User Result node to return the image from your published workflow, or any node that consumes an
image(or afiletarget).
Notes / limits
- Runs on the server. Image Gen executes server-side. You can run it on its own to preview output without running the whole workflow.
- Handles follow the model. Changing the model can add, remove, or retype handles; edges pointing at a handle that no longer exists are cut automatically.
- Multiple references allowed. Image/file input handles accept more than one connection, so you can combine several references for models that support it.
- Item behavior follows upstream input. A Batch, multi-select Choose Output, or LLM structured list makes Image Gen run once per incoming item. See Lists & single values.
