Stability AIStable Diffusion

Stable Diffusion 3.5 Flash

Stable Diffusion 3.5 Flash is a distilled version of Medium exposed through the current API. The documentation describes four-step generation, compared with the longer sampling process of Medium.

Model design and access

The shared generation endpoint supports text-to-image and image-to-image requests. Image-to-image needs a starting image, strength and the appropriate mode. Flash should be selected explicitly through the model parameter.Stable Diffusion 3.5 API reference

Practical use

Practical guidance. Flash fits applications where quick image proposals matter more than maintaining the exact response of an older checkpoint. Compare it with Medium using representative layouts and subjects. Keep the hosted API contract separate from plans for local inference, since a documented endpoint does not establish downloadable weight access.
