Stable Diffusion 3 (SD3) is the latest text-to-image generation model from Stability AI, offering superior realism, detail, and color accuracy compared to its predecessors. It outperforms other models like SDXL, DALL·E 3, and Midjourney v6 in visual aesthetics, prompt following, and typography based on human evaluations. The largest SD3 model, with 8 billion parameters, runs on a 24GB RTX 4090 and generates 1024x1024 images in 34 seconds with 50 sampling steps. Multiple versions from 800M to 8B parameters will be available to suit various hardware. The SD3 API allows developers and businesses to integrate advanced image generation technology into their applications, while the SD3 demo showcases its capabilities.
