About Stable Diffusion 3 Medium

Stable Diffusion 3 Medium is Stability AI's most advanced open text-to-image model, featuring 2 billion parameters. It delivers exceptional photorealistic quality with innovations like a 16-channel VAE for realistic hands and faces. The model excels at understanding long and complex prompts involving spatial reasoning, actions, and styles. It leverages a Diffusion Transformer architecture for high-quality typography with fewer errors. SD3 Medium is resource-efficient, running on standard consumer GPUs with low VRAM footprint, and supports fine-tuning for customization. The model's weights are released under an open Community License, with large-scale commercial use requiring a separate license. It also benefits from optimizations by NVIDIA (TensorRT) and AMD for enhanced performance.
