Introduction of stable_diffusion_3_medium
Model Details of stable_diffusion_3_medium
Model Overview
Stable Diffusion 3 Medium
Model
Stable Diffusion 3 Medium is a Multimodal Diffusion Transformer (MMDiT) text-to-image model that features greatly improved performance in image quality, typography, complex prompt understanding, and resource-efficiency.

Model Description
- Developed by: Stability AI
- Model type: MMDiT text-to-image generative model
- Model Description: This is a model that can be used to generate images based on text prompts. It is a Multimodal Diffusion Transformer ( https://arxiv.org/abs/2403.03206 ) that uses three fixed, pretrained text encoders ( OpenCLIP-ViT/G , CLIP-ViT/L and T5-xxl )
