About Stable Image Ultra
Stable Image Ultra is Stability AI's top text-to-image service in the Stable Image line, aimed at realism, fine detail, and complex composition. It is suited to polished assets such as product scenes and richly described environments where lighting and materials matter. Compared with Stable Image Core it is the choice when final quality outweighs how quickly you need a rough draft.
Where it works well
- Tuned for realism and fine detail, so it suits scenes that must look photographed or carefully rendered.
- Handles long, descriptive prompts with many elements better placed than a draft-oriented model.
- Lighting and material treatment are central to its positioning, helping product and environment shots.
When to choose another model
- It is meant for finished work, so for bulk early drafts Stable Image Core is the lighter option.
- Text-only input means no reference image; use Style Guide or Control for guided results.

FAQ
What is Stable Image Ultra?
Stability AI's quality-focused text-to-image service in the Stable Image line, emphasising realism, fine detail, and complex composition. Use it for assets that will be seen at full size, such as hero images and product scenes.
When should I choose Ultra over Core?
Choose Ultra for polished final visuals with demanding light and material, and prompts that describe many elements. Choose Core for quick, plentiful drafts and general illustration where reaching a usable starting point quickly matters most.
Does Ultra take reference images?
Ultra generates from the prompt alone. For guidance from an existing image, use Control Sketch, Control Structure, or Style Guide, each of which takes an image together with a text prompt.
Can Ultra be used for product photography style images?
Yes, the catalog description names product scenes as a fit, especially where lighting and materials need careful treatment. Describe the surface, light direction, and setting, then review the outputs for accuracy of shape and any lettering.
Which file format does Ultra return?
The catalog lists no fixed output format for this model, so check the API response rather than assuming one. Build your pipeline to read the format from the result and convert it if your downstream tools need something else.
How much does Stable Image Ultra cost?
On TokenLab, Stable Image Ultra costs $0.08 per image. The pricing table above shows the full breakdown. Rates depend on the billing unit, specification, and usage. Compare matching conditions in the model's detailed pricing; a single rate does not determine the total cost.
