Reasoning models
Models that spend tokens thinking before they answer. They win on multi-step problems — planning, maths, debugging, anything where the first plausible answer is usually wrong — and they cost more per call for exactly that reason.
They take different parameters
This is the practical trap. Reasoning models reject some of the parameters ordinary chat models expect, and a request that works against one will be refused by the other. odnoga reconciles the request to the model it actually routes to, so switching a route from a chat model to a reasoning model does not mean rewriting the call — which is the whole point of choosing the model by rule instead of in code.
Pay for thinking only where it pays
Thinking tokens are billed like any other output, so a reasoning model on a simple classification task is money set on fire. The pattern that works: a cheap model on the hot path, a reasoning model behind an escalation rule for the small share of requests that need it. Route by rule, measure both with the same evaluation cases, and let the numbers decide.
Vendor cost is the list price. Your price is that plus your plan margin — the same figures that appear on your invoice.

Narrow it differently
The widest range on the gateway, and the widest price range with it — from the cheapest token on odnoga to the most expensive.
A compact, reasoning-heavy family with large context and near-universal caching.
Models that take 200,000 tokens or more in a single request — roughly a long book, a full codebase, or a year of support tickets.
Or read how the gateway picks between them: routing and fallback, and what it costs: plans and margins.
