Who actually serves your request
One schema in front of all of them. Prices below are what each route costs us — a direct provider's published rate, or an OpenRouter rate with their 5.5% credit fee in it. We add no spread of our own to either.
85% of our 335 enabled routes — 286 of them — go to OpenRouter, another gateway, rather than to a direct contract with the company that made the model. That is what lets this catalogue list models we hold no account for.
Those routes cost more than the number OpenRouter publishes, and the rates here say so. We do not buy tokens from them, we buy their credit, and a dollar of it costs $1.055 — so a route they list at $10.00 per million costs us $10.55, and $10.55 is what the catalogue charges. The 5.5% is theirs and it is inside the rate you can see. We add no spread of our own to either kind of route.
Two consequences worth having before you route production traffic. For a model that only reaches you through OpenRouter, we cannot be cheaper than OpenRouter — their fee sits under ours, and what you are buying is the breadth of one catalogue on one balance. And a brokered route is one more company between you and the model, with its own terms and its own outages. Bringing your own key for a vendor takes us out of that path for their models, and costs nothing.

OpenRouter
Another gateway, used here as a provider. Most of the catalogue is reachable through OpenRouter rather than through a direct contract with the model's maker, which is how Multigrid can list models it has no account for. Where we hold a direct route, that one is priced and tried on its own merits.

What “bring your own key” means here
A provider marked that way is one this deployment holds no platform key for, so we cannot bill its usage to your Multigrid balance. Add your own key on the provider keys page and every model it serves becomes available immediately — and that traffic carries no fee from us at all, because you are paying the provider directly.

Where a model has several routes, the cheapest is tried first — each route is ranked by its own completion price, so the order is per model rather than a standing ranking of providers. Your own keys come before all of them, and a request can override the ordering with provider: { sort: "price" | "latency" | "throughput" } — the last two are ranked from our own measured traffic, and providers we have not measured keep their catalogue position rather than being assumed slow. A provider showing zero has a key but no routes yet.
One key instead of six
Every provider above is a separate account, billing relationship and key if you go direct. Signing up here takes no card and commits you to nothing — and if you already hold contracts with any of them, bring those keys and we charge nothing at all on that traffic.
