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.
