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

Feature	What It Means for You
Single, human-readable URL	Example: qwen7b.gaia.domains/v1
OpenAI-compatible	Drop-in replacement for api.openai.com—same JSON, same headers
Load-balanced cluster	Traffic is routed across one or many nodes; no single point of failure
Fixed LLM + embeddings	Every node in the domain runs the same model family, so responses stay consistent
Free dev keys	Enable Developer Free Trial, mint a bearer token, and start calling

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

Domain	Model / Use Case	Good For
llama8b.gaia.domains	Llama 3.1 8B + tool calling	General chat & prototyping
whisper.gaia.domains	Whisper v2 Large	Voice-to-text & transcription
portrait.gaia.domains	Stable Diffusion Realistic Vision V6	Photo-realistic image generation
coder.gaia.domains	STOA Coder LLM	Multi-language code help
qwen7b.gaia.domains	Qwen 7B	Non-English tasks & translation

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.
