Omnia Model Hub — One API, every model, verifiable supply
Omnia (Omnia Model Hub) is a neutral marketplace for model inference API calls. It gives developers one OpenAI-compatible endpoint, lets suppliers publish their own quotes for the same model, verifies supply with probes and five-level trust grades, and charges a buyer-side transaction fee on each successful call.
What Omnia is
Omnia trades inference service, not model weights and not transferable tokens. A listing is one supplier's offer to serve a specific model in a specific region at a published price, latency and availability level.
A buyer registers, creates an API key, and calls a single endpoint. Omnia routes the request among eligible suppliers, meters input, cached-input and output tokens, and produces a recomputable bill.
- One OpenAI-compatible base URL with /chat/completions, /responses, /embeddings, /images, /audio and /batch endpoints.
- Multiple suppliers quote the same model, so price and first-token latency are compared side by side.
- Every quote is backed by probe records, fingerprint comparison and a five-level trust grade.
- English is the primary interface language and Simplified Chinese is available on every page and screen.
How a call is priced
Prices are quoted per one million tokens. Input, cached input and output tokens are metered separately. Money is kept in fixed-point decimal arithmetic with six decimal places.
A buyer-side transaction fee of 5 percent is applied to the call subtotal. The rate is versioned and adjustable by an administrator; it applies to the next settled call, never retroactively. Failed retries and empty completions are not billed. Auxiliary services such as web search are billed as separate lines.
Built for global use
Omnia is designed for an international audience. The product name is Omnia, with 万象 as its Chinese name. The system does not use the words exchange, trading platform, trading market or trading centre in its legal or product naming.
Payments are intentionally not connected during development. The platform can be tested end to end with offline credit, and a payment adapter is added only after launch preparation.
Invite credit, not cash
Every new account automatically receives one invite link. When a friend registers through the link and completes a qualifying first top-up, the inviter receives platform credit. The credit can only offset Omnia model-call bills.
Invite credit cannot be withdrawn, transferred, exchanged for cash, or used to top up another account. Service credit is also non-withdrawable. The two balances are stored in separate ledgers. Sharing the link requires disclosure of the material connection.
