What is Stable Diffusion?

Stable Diffusion broke the mold in 2022 by making high-quality AI image generation free and open source. Unlike closed competitors like DALL-E or Midjourney, you can run it locally, modify the code, and train custom models without subscription limits.

It's perfect for developers, researchers, and creatives who want full control over their AI image generation. You can integrate it into apps, fine-tune models for specific styles, or just generate unlimited images without hitting paywalls.

Three years later, it's still the go-to choice for anyone serious about AI art who values freedom over convenience. Yes, newer models exist, but none match SD's flexibility and community ecosystem.

The Stable Diffusion XL version is very cost-effective. Although it lacks semantic understanding and is not very stable, its excellent image performance and rich ecosystem of creators make it very suitable for content tools.

format_quote

If all you want is a one-off picture, stable diffusion is great. It's very easy to generate something that'll make you go "I'd print this and hang it on my"

format_quote

But yes, I probably wouldn't only use stable diffusion based models in 2025 (or 2024), but I still think they're a useful tool in the toolbox
