How these prices form
Omnious has no price list. Providers quote input and output rates per million tokens in USDC, and every request is an RFQ: the quotes competing for that model class enter a live scoring auction that weighs quoted price against router-measured latency and reliability.
The winner clears under second-score/3 rules. It is paid a price capped by the next genuine rival's score, so quoting low to win and billing high is structurally impossible. Settlement is pay-as-you-go USDC on the actual token counts of the response, and every response carries a signed, verifiable receipt.
Every figure on these pages is therefore a reading of the market at a point in time: the best asks on the book, and the average cleared prices of requests that settled. They move whenever the market does.
