The Google Imagen family has different constraints per model. Before you use one, call GET /v1/models to confirm the model is currently in the catalog.
| Model | Notes |
|---|---|
everyais/imagen-4-ultra | Only n=1 is allowed (1 image limit) |
everyais/imagen-3-0-capability-001 | Edit-only — use it with POST /v1/images/edits for inpainting, outpainting, and background replacement |
Common constraints follow the endpoint docs — generation allows n up to 10, editing allows n up to 4.
