Verdict
For concept and key art on a subscription; you own what you make on any plan, but studios over US$1M a year need Pro or Mega, and images are public unless you pay for Stealth.
For Unity 6 users who want AI inside the editor: credits are included on Pro, Enterprise and Industry, while Personal gets a 14-day trial and then a paid subscription. Unity says you own the outputs, but third-party generator terms also apply.
