How much does AI Horde cost to use?

AI Horde is free to use with no credit card required. Users can earn 'Kudos' priority by donating GPU time or purchasing them via Patreon, but anonymous users still have access at lower priority.

What models are available on AI Horde?

The platform supports Stable Diffusion models including SD 1.5, SDXL, and community checkpoints, as well as open LLMs. A large catalog of community SD checkpoints and LoRAs is available through the worker network.

Can I integrate AI Horde with existing creative tools?

Yes, AI Horde integrates with Krita, Blender, ComfyUI, Automatic1111, SillyTavern, KoboldAI, and Discord bots. It also provides a well-documented REST API for custom implementations.

Is AI Horde suitable for production applications requiring strict latency?

No, AI Horde does not offer SLA-grade latency, uptime guarantees, or commercial support. Service quality, queue depth, and model availability fluctuate based on the volunteer worker supply.

In short

AI Horde provides free, crowdsourced inference for Stable Diffusion images and LLM text via a decentralized GPU network. It is best for hobbyists and indie developers seeking a cost-free, open-source alternative to proprietary AI services without vendor lock-in.

Best for

Pick AI Horde if you want a free, open, no-lock-in Stable Diffusion or LLM backend and you're happy to trade latency guarantees for zero cost.

Skip if

Skip it if you need predictable latency, an SLA, enterprise compliance, or guaranteed access to a specific proprietary model.

AI Horde (originally Stable Horde) is a decentralized, volunteer-powered inference network that lets anyone generate Stable Diffusion images and run LLM text completions for free through a shared pool of community-donated GPUs. Users hit a web UI or REST API; workers around the world pick up jobs and return results. A 'Kudos' priority system rewards people who contribute compute, while anonymous users still get access at lower priority.

It's run by Haidra, a non-profit backed by donations and NGI0 Core funding, and the entire stack (server, workers, bridges to Automatic1111, ComfyUI, KoboldAI, etc.) is open source. The big differentiator is the absence of vendor lock-in or billing: there's no credit card, no per-token pricing, and no proprietary endpoint. That makes it a credible choice for hobbyists, researchers, and indie developers who want a real generative-AI backend without paying OpenAI/Stability/Replicate rates.

The trade-off is that quality of service depends on the swarm: model availability, queue depth, and worker reliability fluctuate, and SLA-grade latency is not on offer. Integrations include Krita, Blender, Discord bots, KoboldAI, SillyTavern, and dozens of community clients that treat the Horde as a drop-in inference backend.

Editor's take

One of the few genuinely altruistic projects in generative AI: a non-profit volunteer cluster that gives hobbyists and indie devs a real Stable Diffusion and LLM backend for nothing. Quality of service depends on the swarm, but as a free fallback or a way to prototype against an open API it's hard to beat.
