Stable Diffusion
Free alternative to: Midjourney
License: OpenRAIL (CreativeML OpenRAIL-M for SD 1.x, OpenRAIL++-M for SDXL)
Free terms: Model weights free under OpenRAIL licenses with commercial use, modification, and redistribution permitted; carries use-based restrictions (no unlawful, discriminatory, misinformation, or automated legal-decision uses).
What it does
Stability AI's landmark open-weight text-to-image diffusion model — run locally, fine-tune it, and build on top of it.
Heads-up: Not OSI-certified, but practically open: commercial use, modification, fine-tuning, and redistribution are all permitted; SDXL also allows selling outputs-as-a-service. Some community fine-tunes layer extra publisher terms — check each model card.
