ServerlessImageImg2Img

2 billion parameter SD3 model with optimized performance and excels in areas where previous models struggled, such as photorealism and typography. The Stable Diffusion 3 API is provided by Stability and the model is powered by Fireworks. Unlike other models on the Fireworks playground, you'll need a Stability API key to use this model. To use the API directly, visit https://platform.stability.ai/docs/api-reference#tag/Generate/paths/~1v2beta~1stable-image~1generate~1sd3/post

Serverless API

Stable Diffusion 3 Mediumis available via partnership with Stability AI, in which Fireworks powers the underlying API. You must use a Stability API key and will be billed by Stability for usage, instead of Fireworks. See the API code example below or see the Stability API docs for full details.
