So this sounds like BOINC but specifically for language neural nets?

It's a very interesting concept, and I quite like the idea of a public, open compute cloud. I'd like to see more detail on security: if I'm going to donate time on my personal machine, I'd like some assurance that the workload is properly sandboxed and can't reasonably access my network or data.

Mostly out of interest, what's the advantage to this over just using the existing BOINC network? I've been running BOINC on and off since the dialup days, it's an extremely mature platform with all kinds of workload capabilities.
