About this API

Stability AI is a UK AI company founded 2020, famous for releasing open-source Stable Diffusion in 2022 — sparking the open-source AI image generation explosion. Business model is dual-track: open-source models for community research and free use, SaaS API for commercial customers. But Stability AI as a company experienced turbulence — 2023 founder Emad Mostaque left over financial issues, multiple funding rounds and layoffs in 2024, plus Midjourney/FLUX/DALL-E 3 overtaking quality has lowered Stable Diffusion's standing in the creator community. API still provides SD3, SDXL model hosting, but many developers have migrated to Replicate (cheaper) or FAL (faster) third-party inference platforms.
