How to run Stable Diffusion 3.5 Medium on Modal

Introduction to Stable Diffusion 3.5 Medium

Stable Diffusion 3.5 Medium is a powerful image generation model with 2.5 billion parameters that is designed to run “out of the box” on consumer hardware, striking a balance between quality and ease of customization. It is trained on 1024x1024 images, and is most suitable for generating images with those resolutions.
