Can we use a System One model in the browser?

I ran Laya, an open 421M-parameter decision model, in a browser tab and measured what it costs: download, speed and accuracy. In mid-September, TypeSafe AI released Jev, a “System One” model. It doesn’t write text. You give it some input and a few typed questions, and it gives back answers with pro…
