Most of us have a graphics card that sits idle for twenty-three hours a day, and AI Horde puts it to work for strangers. Volunteers run worker programs on their own computers, and anyone can send them a prompt from a web page with nothing to install. A volunteer-run non-profit called Haidra operates it, the code is AGPL-3.0, and it lives on donations and a grant from NLnet.

AI Horde scores a 5 on power, a 4 on footprint, lock-in and self-direction and a 3 on longevity and delivery.

You can use the shared anonymous key with no sign-up, though anonymous requests wait at the back of the queue. Priority comes from kudos, a points system the project says can never be bought or sold, so the way to move up is to lend your own graphics card. You get the models the volunteers choose to host, and capacity depends on who turns up.

  • Run by a non-profit on donations and an NLnet grant, with AGPL-3.0 code
