Free community-powered AI generation service
AI Horde is a free, community-powered generation service where volunteers share spare computer power to generate images and text for anyone. It relies on open-source image and text generation workers. Users can generate content through websites, bots, or apps without coding, while contributors can run workers to share idle GPU/CPU power and earn kudos. The platform offers a REST API for developers, with live status stats and no vendor lock-in. It is funded by public donations and supported by NLnet / NGI0 Core, and is run by Haidra, a volunteer-based non-profit.
