Model overview

Stable Diffusion 3.5: features, use cases and important details

Stable Diffusion 3.5 is Stability AI’s active text-to-image model family introduced on October 22, 2024. The original release included Stable Diffusion 3.5 Large and Large Turbo, with additional variants expanding the family for different quality, speed and hardware targets.

What SD3.5 improves

Stability describes the family as improving image quality, typography, complex prompt understanding and resource efficiency. The models use the Stability AI Community License and can be downloaded for local workflows, fine-tuning and custom creative applications.

Current API variants

Stability’s current pricing page lists SD3.5 Large, Large Turbo, Medium and Flash. These services are billed in credits rather than text tokens, with different prices reflecting speed and quality tradeoffs.

Who should use it

SD3.5 is a better starting point than older SDXL or SD3.0 models for new Stability-based image projects. Teams should still review licensing conditions, test prompt adherence on their own creative workloads and apply appropriate review for generated people, text and branded content.
