People forget that LLM code cannot be covered by copyright. So LLM code cannot be placed under an open source license
It's a bit like saying speed limits don't apply on private property, therefore you can't have any traffic rules on your private racetrack.
That’s not how copyright works. If you don’t own the code, you can’t release it under a license. The question of how much human editing is needed to establish copyright is a huge question right now.
