Image generation models offered as hosted API and open weights
Stability AI is the company behind the Stable Diffusion family, offering image models both as hosted API endpoints and as downloadable weights. The hosted side covers text-to-image, inpainting, erasing and replacing objects, upscaling and structure-guided generation, billed per image. The open side is what made the company well known: checkpoints you can download, run locally or fine-tune on your own hardware, subject to the licence attached to each model. Audio and video models round out the catalogue, though image work remains the core.

Yes for the open-weight releases, which is how most people meet the family. Self-hosting means you supply the GPU, manage the environment and accept the licence terms attached to that specific checkpoint, which differ between models.
The hosted service bills by generation, so a busy image pipeline costs more than an occasional one. Rates and included credits change, and there is no permanent free tier for production use, so estimate against your expected volume.
It depends on the licence of the model you used and your account tier. Some releases permit commercial use, others restrict it, and the hosted service has its own terms. Read both before shipping generated images in a product.
