Stable Diffusion 3.5 Medium is a Multimodal Diffusion Transformer with improvements (MMDiT-x) text-to-image model that features improved performance in image quality, typography, complex prompt understanding, and resource-efficiency.

Usage & Limitations

While this model can handle long prompts, you may observe artifacts on the edge of generations when T5 tokens go over 256. Pay attention to the token limits when using this model in your workflow, and shortern prompts if artifacts becomes too obvious.The medium model has a different training data distribution than the large model, so it may not respond to the same prompt similarly.We recommended to sample with Skip Layer Guidance for better struture and anatomy coherency.
