Stable Image Ultra
Stable Image Ultra is Stability AI's premium image generation tier, targeting maximum output quality, coherence, and detail. It sits at the top of Stability AI's commercial API offering, using a more powerful underlying architecture than Stable Image Core to deliver sharper textures, more accurate prompt adherence, and stronger handling of complex compositions.
Stable Image Ultra is the right choice when output quality is a primary constraint — such as for hero imagery, high-end creative campaigns, detailed character art, or any application where generated images will be viewed at full resolution. The added quality comes at higher latency and cost relative to Core, making it best suited for lower-volume, quality-critical workflows rather than bulk generation.
