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 can handle text in many languages, which most text models of this kind do not. 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.

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-code-4 is a code embedding model from Voyage AI, a MongoDB company. It is designed for coding agents and code retrieval, with Matryoshka embeddings at 2048t voyage-code-4 here: [mongodb.com/products/platform/ai-search-and-retrieval/models](https://www.mongodb.com/products/platform/ai-search-and-retrieval/models?utm_source=OpenDunes&utm_medium=referral)
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.
