AI Horde is a free, community-run, open-source crowdsourced network where volunteers share their GPUs so anyone can generate AI images and text in a browser.
About
AI Horde is a free, community-operated service that lets anyone generate AI images and text without installing software or paying for a subscription. It solves a practical problem: running generative AI models locally requires expensive hardware, while commercial services typically charge per image. AI Horde instead crowdsources computing power from volunteers around the world.
Visitors submit prompts through a web interface or third-party GUIs, and a distributed network of volunteer-run workers processes the requests. The project is operated by Haidra, a volunteer-run non-profit, funded by public donations and NLnet / NGI0 Core. It is open source, with code available on GitHub, and users can contribute by running a worker, donating, or earning "kudos," the community's internal credit system. The platform supports multiple models, including AlbedoBase XL, Flux.1-Schnell, Stable Cascade, DreamShaper XL, Juggernaut XL, and Cheyenne, and offers a documented REST API for developers.
