The Chrome model requires either "16 GB of RAM or more and 4 CPU cores or more" or "Strictly more than 4 GB of VRAM", and "22 GB of free space" (it uses around 4.4GB but it doesn't want to use the remaining free space).

The model is pretty slow on my M4 Pro mac.

The API allows the browser to use a cloud service instead, but then privacy is lower. So, more privacy for the rich.
