rerank-2

Rerank 2 expands Voyage's earlier reranking family with improved general and multilingual retrieval.

Model design

The release evaluates 93 datasets, including 51 multilingual datasets in 31 languages. Its 16,000-token pair limit is twice that of rerank-2-lite. Both models score a query and document jointly.rerank-2 and rerank-2-lite

Practical use

Practical guidance. Use the larger pair limit when evidence is spread across a long candidate document. Keep an eye on which text reaches the model; silent truncation can remove the passage needed to judge relevance.
