A browser extension enables local image generation using SDXL models via WebGPU, running on the user's GPU without external setups. The tool supports two models: SDXL-Lighting fp16 (7 GB) and a 4-bit version (3.6 GB), with requirements including at least 8 GB VRAM for the full model and a browser with WebGPU support (Chrome/Edge 122+ or latest Firefox).
