Public Gaia Domains: Zero-Setup Access to Decentralized LLMs

Running your own Gaia Node is great when you need full control, but sometimes you just want to call an LLM endpoint and ship your product. Now you can use public Gaia Domains: ready-made, open-source models you can hit from Postman, LangChain, an IDE plug-in—anything that already works with the OpenAI HTTP spec.
Below is a quick primer on what public domains are, the problems they solve, and how to start querying a model like qwen7b.gaia.domains in under five minutes.
Gaia Public Domain
Think “ENS for AI”—but instead of mapping a name to a wallet address, we map it to a pool of self-hosted LLM nodes on the Gaia network.
Why Public Domains Matter
- Zero InfrastructureNo GPU? No problem. Skip the node install and start building.
- Instant DiscoveryShare mybrand.gaia.domains with a teammate; they will have everything they need to connect.
- True DecentralisationEven these shared domains still run on independent nodes. There’s no central server that can be shut down or censored.
- Specialised KnowledgeDomain operators can fine-tune on docs, SDKs, or industry data—so you get answers that are actually useful (see the MetaMask example below).
Tour of Popular Public Domains
Fast-Track: Calling Qwen 7B From an API Client
• Create / Enable a Developer Key Log in → Settings → API Keys → toggle Developer Free Trial. Copy the newly generated Bearer token.
• Set Up Your Request
• Send — the response comes straight from the decentralised cluster.Example output:
The same key works for any other public domain; just swap the URL and model name.
Behind the Scenes: How a Domain Works
- Load Balancer distributes the call to the least-busy node.
- Single-Model Policy ensures every node in that domain runs exactly Qwen 7B with the nomic-embed embedding model.
- Response flows back through the domain endpoint—no additional headers or weird auth required.
If you later spin up your own node that meets the domain’s policy, you can request to join the cluster and earn traffic-based rewards.
From Hobby to Production: Owning Your Domain
Public endpoints are perfect for prototyping, but when you need:
- Brandable name
- Custom knowledge base
- Control over which nodes participate
- Optional token-metered pricing
… launch a private Gaia Domain:
- Assets → Launch Domain
- Pick a tier (Bronze → Supreme) for future staking rewards.
- Point your existing node(s) at the domain—and you’re live.
That single URL becomes the gateway for your customers, bots, or on-chain agents to hit your LLM.
