Switching between GPU and Lite Web version
Open the model menu at the top and choose GlirOS Helper (GPU) or GlirOS Helper (Lite). Settings > Models shows both, with Load and Unload. If the graphics card is not supported by the browser, only Lite works; a current Chrome or Edge usually supports WebGPU.
This guide is the same text GlirOS itself uses to answer questions about GlirOS.
