The base model can be found on HF (https://huggingface.co/wave-on-discord/gemini-nano) and run in any web browser using MediaPipe on WebGPU: https://x.com/niu_tech/status/1807073666888266157

As for temperature and topK, you can set them in the AITextSessionOptions object as an argument to `window.ai.createTextSession(options)` (source: https://source.chromium.org/chromium/chromium/src/+/main:thi...)

You should also be able to set it by adding the switches: `chrome --args --enable-features=OptimizationGuideOnDeviceModel:on_device_model_temperature/0.5/on_device_model_topk/8` (source: https://issues.chromium.org/issues/339471377#comment12)

The default temperature is 0.8 and default topK is 3 (source: https://source.chromium.org/chromium/chromium/src/+/main:com...)

As for LoRA, Google will provide a Fine-Tuning (LoRA) API in Chrome: https://developer.chrome.com/docs/ai/built-in#browser_archit...
