Closed translation models
17 in the catalogue today. Every one with what it costs, who sells it and where it stands.
Models and services aimed at moving text between languages. A general chat model will translate too, and often well; a dedicated one earns its place with glossaries, formality control, document formats it keeps intact, and rates that assume volume. Check which direction was measured — most quality figures are for translating into English, and the other direction is harder.
Models whose weights are not published and which are bought through somebody's API. You get the maker's infrastructure, their scale and their uptime, and no way to run the thing yourself or to keep it if it is withdrawn. Most of the strongest models are here, so this is less a choice than a fact about the market; the choice is which seller you buy the same model from, and the catalogue holds their prices side by side.
