I did a WebGPU-based HTML Single-File Chat Application even for larger models. It just depends on your machine. It is cool to show people what can be done on their machines without installing anything. It also works in air-gapped environments.

Which browser do you use?
The 1060 is unusually slow. The Mac mini sounds about right. Have fun playing around and sharing. With the more VRAM of the mini you can also run Qwen 3.8 27b :)
I really like to showcase this to non-tech people to show what their home machines already can do WITHOUT INSTALLATION in an air-gapped scenario! And given all the recent fuss, we should not trust the big providers at all with important data.
