Stability AI
Open generative AI for image, video, and audio synthesis
Stability AI develops foundational generative models for images, video, audio, and 3D content. Their open source Stable Diffusion family has become a cornerstone of the AI image generation ecosystem, enabling a broad community of developers, researchers, and artists. Integrated into Runware, Stability AI architectures power thousands of community fine-tuned models with reliable, high performance inference.

Stable Diffusion XL Refiner 1.0 is the refinement checkpoint in the SDXL 1.0 pipeline. It is trained for the final denoising steps on existing SDXL latents or image-to-image inputs, making it useful when a base SDXL generation needs cleaner fine detail, stronger local texture, and a more polished final pass rather than a full standalone generation workflow.
Stable Diffusion XL v1.0 VAE Fix is the SDXL 1.0 base checkpoint packaged with a corrected VAE for more stable inference. It keeps SDXL's strong prompt understanding, broad visual range, native 1024x1024 generation, and support for both text-to-image and image-to-image workflows, while reducing the artifact and decoding issues associated with the original embedded VAE.
