📋 About Stable Diffusion
Stable Diffusion is an open-source AI image generation model developed by Stability AI and released in 2022. Unlike Midjourney or DALL·E, Stable Diffusion can be downloaded and run entirely on your own computer giving complete privacy, no usage limits and total creative freedom.
The open-source nature has spawned a massive ecosystem of custom models, fine-tunes and interfaces like Automatic1111, ComfyUI and InvokeAI. Artists and developers have trained thousands of specialised models for anime, photography, illustration and specific subjects.
Stability AI also offers DreamStudio, a web-based interface for Stable Diffusion with pay-as-you-go credits starting at $10 for 1000 generations. Stable Diffusion 3 and SDXL are the latest models with significantly improved quality.

I integrated SDXL via the Stability API into our product and the cost is a fraction of competing services. The image quality is competitive with Midjourney for most use cases.
