Voyage AIVoyage 2

voyage-large-2-instruct

Voyage Large 2 Instruct uses task instructions to shape text embeddings. It is an encoder, not a conversational instruction model.

Model design

The release supports retrieval, text classification and clustering. Instructions describe the relation that the vector should preserve. The API's query and document modes supply retrieval prompts; task-specific instructions can be important for other uses.voyage-large-2-instruct

Practical use

Practical guidance. Decide whether similarity should mean shared topic, shared intent or evidence for a query. Use that definition consistently when embedding the data. A clustering instruction and a retrieval instruction can produce different useful neighborhoods from the same text.
