The fonts seem to have little Unicode coverage (no Greek letters for example), which is one thing that I wouldn’t expect an AI to have a problem with.

No thanks. Not only for the AI, but I've tried to write a little japanese and all the fonts appear blank.

and after beta?

Please stop plugging AI crap on HN. If the relevance of human creativity is indeed breathing its last gasp, let us enjoy it in peace.

And if not, then AI is overhyped and plugging it is even less justifiable.

Either way, just stop.
