SDXL running locally in the browser on WebGPU, open-source

An open-source browser extension has been released that enables local image generation using the SDXL model via WebGPU, eliminating the need for complex installations. It supports two model versions: SDXL-Lighting fp16 (approximately 7 GB storage, requiring around 8 GB VRAM) and a 4-bit variant for lower-spec hardware (about 3.6 GB storage, needing 4-5 GB VRAM). This development allows practitioners to run image generation models directly in the browser, albeit with noted performance limitations due to synchronous WebGPU shader compilation, providing a new approach to leveraging AI models without extensive setup.
