AI](https://stability.ai/membership) ## Description: Stable Diffusion 3 Medium is Stability AI's text-to-image model that features greatly improved performance in image quality, typography, complex prompt understanding, and resource-efficiency. Compared to previous versions of Stable Diffusion versions, Stable Diffusion 3 leverages a novel Multimodal Diffusion Transformer (MMDiT) architecture that combines a [diffusion transformer architecture](https://arxiv.org/abs/2212.09748) and [flow matching](https://arxiv.org/abs/2210.02747). We have optimized the model's speed using NVIDIA's TensorRT (TRT), resulting in significant acceleration with no quality loss.
