Harvey announced BigLaw Bench – Retrieval, a benchmark for legal document retrieval. Its proprietary retrieval system outperforms embedding and reranking methods from OpenAI, Voyage, and Cohere, identifying up to 30% more relevant content across contracts, discovery emails, and research databases. The system uses metadata, recency features, and LLM-based reasoning to improve retrieval in legal domains.

## Evidence

Verbatim from https://www.harvey.ai/blog/biglaw-bench-retrieval:

> On these tasks, Harvey’s retrieval system outperforms commonly used embedding-based and reranking methods, identifying up to 30% more relevant content than alternative retrieval methods from OpenAI and other embedding model providers (Voyage, Cohere) across a diverse range of legal document types.
