Unity Core ML Stable Diffusion Plugin

Stable Diffusion plugin for Unity, based on Apple's Core ML port. You can run the model on-editor and at-runtime without needing any extra components.

System Requirements

Unity 2023.1 or later
Apple Silicon Mac (editor/runtime support) with macOS 13.1 or later
iPad Pro with Apple silicon (runtime support) with iOS 16.2 or later

Although the plugin supports iOS, it requires huge amount of memory to run the model, so it only supports memory-rich iPad models.

How To Try

Before running the sample project, you must put the model files in the Assets/StreamingAssets directory.

Clone or download the pre-converted Stable Diffusion 2 model repository.
Copy the split_einsum/compiled directory into Assets/StreamingAssets.
Rename the directory to StableDiffusion.

It takes a long time (a few minutes) for the first run. After this initialization step, it only takes a few tens of seconds to generate an image.
