Stable Diffusion 3.5 Large
Stable Diffusion 3.5 Large, developed by Stability AI, is an open-source image generation model with 8 billion parameters using the MMDiT (Multimodal Diffusion Transformer) architecture. The model generates high-quality images from text descriptions with excellent prompt adherence, compositional accuracy, and text rendering capabilities. Building on Stable Diffusion 3, it improves image quality, reduces artifacts, and better handles complex multi-element compositions. As an open-weight model, it can be self-hosted, fine-tuned with LoRA adapters, and integrated into custom pipelines without API costs. The model has spawned a massive ecosystem of community-built tools, custom models, and specialized adapters for various art styles and commercial use cases. Stable Diffusion 3.5 Large represents Stability AI's commitment to keeping powerful image generation technology freely accessible to the open-source community.
View Stability AI profile →SDXL Turbo
SDXL Turbo, developed by Stability AI, is an open-source image generation model with 3.5 billion parameters designed for real-time image synthesis. The model generates images in a single inference step using adversarial diffusion distillation, producing results in under one second compared to the multi-step process of standard diffusion models. This speed advantage makes it suitable for interactive applications, live previews, and rapid prototyping where instant visual feedback is required. While image quality is somewhat lower than multi-step models like SDXL or Stable Diffusion 3, the speed-quality tradeoff is favorable for many practical applications. Free and fully open-source, SDXL Turbo runs on consumer GPUs and can be integrated into real-time applications. The model demonstrated that diffusion models could be distilled for near-instant generation without catastrophic quality loss.
