AI Horde

What AI Horde is

AI Horde is a free service for image and text generation, with computing power supplied by volunteers. Its browser image studio supports text-to-image generation, reference images and image editing. Tools include prompt refinement, style presets, image-to-image workflows, ControlNet, inpainting, remixing, transparent backgrounds and QR code workflows. Its Alchemy tools can upscale images, restore faces, remove backgrounds, create control maps and produce image descriptions. The service uses open-source models, and the available models and maximum image sizes can change as volunteer workers come and go.

Users can make requests anonymously, though anonymous requests have lower priority and request limits. Priority can be earned through contributions; kudos cannot be bought. Developers can build integrations with the REST API. The maker also lists community frontends, bots, SDKs and plugins, including Discord bots and Python, Node.js and Go SDKs. AI Horde says it anonymizes API requests before dispatching them, and that workers poll for jobs through outbound connections instead of accepting incoming connections. The service has operated continuously since 2022. It is run by Haidra, which the maker describes as a volunteer-run, registered non-profit association in Luxembourg. Live help and discussion are available through the AI Horde Discord server.

Who it suits

AI Horde suits people looking for free image or text generation, including users who can contribute computing power to earn priority. Developers can use its REST API and listed community integrations to build or connect tools.

Limits

The free plan costs nothing. Anonymous use has lower priority and request limits; priority can be earned through compute contributions. Available models and maximum image sizes can vary as volunteer workers come and go.

Getting started

1. Open https://aihorde.net/.
2. Use the browser image studio for image generation and editing.
3. Make an anonymous request, or contribute computing power to earn priority.
4. Use the REST API to build integrations, or explore listed community frontends, bots, SDKs and plugins.
5. Visit the AI Horde Discord server for live help and discussion.

Verdict

Choose AI Horde for free image and text generation with a broad browser studio, open-source models and a REST API. It may suit users less well when anonymous request limits or changing model and image-size availability constrain their work.
