Stable Diffusion 3 Medium / 2B

SD3 Medium’s B-tier recommendation suits revisiting an existing SD3 project or checking an adapter built for this exact model. It is an older downloadable release; keep SD3, SD3.5 and SDXL distinct when choosing a workflow. For a new asset pipeline, compare current alternatives before committing. Read the license included with your download alongside Stability’s current Core Model terms, because licensing changed after launch. The acceptable-use policy separately restricts content relating to sexual acts, including when you self-host. A small model and offline access do not grant permission for every asset category.

Commercial use & license

Read the license included with your exact download and check current Core Model Community License coverage; early SD3 launch summaries may be outdated.

Adult content rules

Stability’s current acceptable-use policy prohibits content relating to sexual acts and applies to self-hosted technology and third-party hosting.
