Closed search models, tools and agents

24 in the catalogue today. Every one with what it costs, who sells it and where it stands.

Models, tools and agents that go and look something up — the open web, a set of documents, a grounded answer with citations. Pricing is usually per call or per result rather than per token, so the cost follows how often you ask. What differs is freshness, how much of each page you get back, and whether you are handed sources you can check or a summary you must trust.

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the maker's infrastructure, their scale and their uptime, and no way to run the thing yourself or to keep it if it is withdrawn.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.
