stable-horde

AI Horde (stable-horde) is a community-powered network for generating AI images and text. Volunteers run open-source image and text generation workers that share spare GPU/CPU power so anyone can generate content for free. The service is accessible through user-friendly frontends (for example, ArtBot), bots, apps, or directly via an open REST API for developers.

The project is donation-funded and run by Haidra, a volunteer non-profit. It includes features for contributors (workers earn kudos) and users (anonymous API usage or registered accounts for higher priority), plus live status and statistics showing workers, throughput, and queue depth in real time.

A crowdsourced distributed cluster for AI image and text generation.
