What is Stable Diffusion?
Stable Diffusion is a family of image-generation models, not one universal free website. Stability AI documents self-hosted licensing, APIs and hosted creation paths, each with different technical requirements and usage conditions.
Identify the exact model and license for the setup you plan to run, then test one prompt before changing the model or runtime. Compare AI image tools
Use the exact Stable Diffusion checkpoint you intend to run for the first test. To assess whether you need that level of setup, try the same brief in Adobe Firefly and compare the available controls and the applicable usage terms.
