Honestly, I think that's the only llm of its kind. The next closest thing is this

If you don't mind something narrower (an expert system, sort of), I'm slowly coding something for myself here. It's not ready yet (about half way done to initial release).

Public facing docs are a bit of a mess at the moment (sorry; writing docs is boring AF; will probably be the last thing I tidy before official 1.0.0) and it's not really runnable right now, but when done, the "source files" for this will be kiwix (off line Wikipedia), your own markdown notes and 30 or so trusted domains (user defined).
So it's all either your own content or public domain aka open source fully. Code itself is AGPL-3.
Anyway, that's the goal.
I guess it depends on your definition of perfect - cheap, good or fast.
This thing is probably going to cost at least $20K USD.
Edit:
"Next year's base M7 processor is expected to arrive in the first half of 2027 and will also upgrade memory bandwidth to about 240 GB/s."
That's...really fucking slow. What's the goal here - CGI, engineering sims, game dev etc? 1.5TB is cool but at 240GB/s that will crawl for AI use.
Comparison: this is about $100K, for 7.2TB/s, 252GB VRAM (+500GB system ram, so closer to 750GB total)
