Full story

The developer of SDXL aimed to simplify local image generation by removing the need for virtual environments or complex installations. To achieve this, they successfully pushed the entire process into a browser, utilizing WebGPU for local execution. This innovation allows users to install a browser extension, load the necessary models, and then generate images offline using their own GPU. The model incorporates text encoders, UNet, and VAE, all of which are ONNX graphs designed to run efficiently in this new browser-based environment.
