voyage-4-lite

by MongodbReleased 27 July 2026

This model turns written text into compact number lists that a search system can compare, so it is built for finding the right passage in a large pile of documents rather than for writing prose. It reads up to about 32 pages in one go and gives back no words at all, so it cannot draft, summarise or answer questions on its own; that work needs a model that writes text. It is the lightest of its family, tuned to answer quickly and cheaply, which makes it a fit when you have a great many passages to sort through and speed matters more than the finest match.

voyage-4-largeMongodb · Jul 27, 2026

This model turns written text into long lists of numbers that a search system can compare, so it is built for finding the right passage in a large pile of documents rather than for writing prose. It reads up to about 32 pages in one go and handles text in many languages, which most models of this kind do not. Its number lists can be shortened to save storage space without losing much of the match quality, a trick few of its kind offer. It gives back no words at all, so it cannot draft, summarise or answer questions on its own; that work needs a model that writes text.

voyage-multimodal-3.5Mongodb · Jul 27, 2026

This model takes in written text and pictures, reading up to about 32 pages at once. For whatever it reads, it gives back a numeric fingerprint that can stand for as much as 28 pages, and software compares those fingerprints to find matches or rank results by closeness. Its work is letting a buyer search a mixed archive of reports, slide decks and photos for the pages that fit a question, and it stops at audio and video, which it does not accept, so those files need a different kind of model.
