Image Model
imageModelSourceEditor-only image model choice: which image-generation model renders art while you build the world — character and NPC portraits, location images, region maps, and area art. Image generation during play is configured separately.
"These choices only affect images generated while editing this world. In-game image model choices are set separately from Usage Settings during play."

}Editor-only image model
This choice affects only the images generated while editing the world — character and NPC portraits, location images, region maps, and area art produced in the studio or the legacy editor. Image generation during play is set separately and is not controlled by imageModelSource.
One selector covers every surface. Choosing a model writes that model's identifier into the field:
| Model | Value |
|---|---|
| GPT Image 2 Low | falai-gpt-image-2-low |
| GPT Image 2 Medium | falai-gpt-image-2 |
| Nano Banana Low | google-nano-banana-lite |
| Flux 2 | falai-flux-2-dev |
The default is GPT Image 2 Medium (falai-gpt-image-2) when the field is empty or absent. The model list changes as models are added or retired, so select from the editor rather than hand-copying an identifier.
Replaces the per-surface models
Earlier worlds carried an imageModelSources object choosing a separate model per surface (portrait, location, region). Loading such a world keeps the portrait model as the world's single imageModelSource and drops the location and region choices.
