Disco Diffusion

🔴Shutdown / Dead

Disco Diffusion was a free Google Colab notebook by Somnai that combined CLIP-guided diffusion with a community-tuned UI, going viral in early 2022 and seeding the prompt-engineering culture later cemented by Midjourney and Stable Diffusion. Active development on the official notebook effectively stopped in late 2022 once Stable Diffusion released and consumed the open-source diffusion community. The notebook still loads but is years out of date and runs poorly on modern Colab runtimes.

Reason for Shutdown

GitHub repo has had no meaningful commits since late 2022; the project's Discord and patrons wound down. Notebook runs only with significant patching.

Artbreeder

🟠Possibly Dead

Artbreeder launched in 2018 as a GAN-based image remix tool where users mixed 'parent' images into new outputs. It grew a strong community of character designers and worldbuilders. The team shipped a 'Collager' and a diffusion-based 'Artbreeder Composer' in 2023, but the platform never matched Midjourney or Stable Diffusion on quality and traffic dropped sharply. The site still loads and the subscription remains for sale, but the changelog and social feeds have gone quiet.

❓ Frequently Asked Questions

Does Disco Diffusion still work?

Technically yes, but the Colab notebook breaks on modern runtimes and image quality is far below 2025 open models.

Why did everyone leave?

Stable Diffusion launched in August 2022 with faster local generation and a more permissive license. The community migrated within weeks.

Who made Disco Diffusion?

Pseudonymous artist 'Somnai' assembled the original notebook on top of CLIP-guided diffusion work by Katherine Crowson and others.

Is there a maintained fork?

Not actively. ComfyUI workflows can reproduce the Disco aesthetic with modern models if you want the look.
