Stable Diffusion

Key facts: Stable Diffusion is the open-weight image model family from Stability AI: describe an image and it generates it, with models you can download and run on your own hardware or use through countless apps and APIs. Later versions add better text rendering, editing and control over composition.

Plans: The model weights are openly available for download, and many apps and APIs offer free tiers or credits for running them; Stability AI also offers its own API with usage-based pricing. Costs depend on where you run the model, not a single subscription.

Best for: creators and developers who want control, local running or open licensing for images. Watch out: open models vary in quality and safety filtering by version and host — check the licence and filters of the specific model you use.
