- 01
Sign in and pick a model
Sign in, then choose an image model and an operation. Text-to-image starts from a description; edit starts from a reference image.

Describe the result
Name the subject, setting and style. The workbench sends your prompt and options to the model you selected.
- 03
Submit and follow the task
Image requests run as background tasks. You can leave the page; the task continues and appears under My creations.
- 04
Download before retention ends
Results are kept for 30 days. Download the ones you want to keep. A failed task produces no result and returns the reserved credit.

Prompt guidance
Start with the subject
Say what the main subject is and what it is doing. A clear subject gives the model less room to invent a different scene.
A ceramic teapot on a windowsill, steam rising, morning light
Set the frame
Mention close-up, wide shot or overhead view, plus the aspect ratio you need. Composition words change the crop more reliably than adjectives alone.
Overhead product shot, centered, square crop
Describe light and material
Light direction and surface texture separate a flat render from a believable image.
Soft window light from the left, matte clay, visible glaze
Name a visual language
Use a style only when it serves the brief. Pair it with concrete details so the result does not turn into a generic imitation.
Editorial food photography, muted palette, no text
Keep text short
Image models still misspell long strings. Keep any in-image words short and put essential copy in the page around the image.
Label the jar with the single word TEA

Common questions
Do I need an account to generate images?
Yes. Sign in before you submit. Generations are charged to your OmniaKey balance at the model's standard rate.
What is the difference between text-to-image and edit?
Text-to-image creates a new image from your description. Edit uses the image you upload as the starting point and applies your instruction to it.
Can I close the page while an image is generating?
Yes. The task runs in the background and appears under My creations. Returning to the page does not restart it.
How long are generated images stored?
Results are kept for 30 days. Download them before then; a failed task produces no result and returns the reserved credit.
Can I use these models through the API?
Yes. The same models are available through the OmniaKey API with the same API key. See the model catalog for model pages and the API documentation for request formats.
