Not necessarily, if a model is public domain, there could still be a lot of proprietary elements used in interpreting that model and actually running it. If you own the hardware and generate something using AI, I’d say the copyright goes to you.

If you rent a brush to paint with, is the painting not yours? If you rent a musical instrument to record an original song with, is the song not yours?
