Who Makes Code-Supernova?

As per title: Seems like a company with frontier capabilities and ability to serve at such scale for Kilocode, Windsurf, Cursor with a galactic themed model would speculatively be xAI no?

For reference: I don't care about politics in the scope of standing on the shoulders of giants.

This seems like a massive effort to collect perpetual coding data to ensure longevity of coding abilities.
