The open-weights option.
Stability AI publishes the Stable Diffusion family — image models you can run on your own hardware\, fine-tune on your own data and deploy without sending anything to a third party.
That control is the reason to choose it: no per-image cost at scale\, no content policy beyond your own\, and full fine-tuning. The cost is effort — you need the hardware and the skills\, and licence terms differ by model\, so check them before commercial use.
