Research-only translation models
2 in the catalogue today, and the list grows as the market does. 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.
Weights published for research and explicitly not for selling. They are here because they exist, are often excellent, and are worth knowing about — and because the cheapest way to learn this is not after you have shipped. If a model on this list is what you want, the maker will usually license it commercially on request; that is a conversation, not a download.
