Harvey partnered with Voyage AI to fine-tune a custom embedding model, voyage-law-2-harvey, on over 20 billion tokens of US case law. The model reduces irrelevant top results by nearly 25% compared to leading off-the-shelf embedding models while using one-third the embedding dimensionality, improving retrieval quality for legal queries.

## Evidence

Verbatim from https://www.harvey.ai/blog/harvey-partners-with-voyage-to-build-custom-legal-embeddings:

> Our custom embedding model, named voyage-law-2-harvey, reduces the amount of irrelevant material returned in top results by nearly 25% compared to the next best off-the-shelf embedding models (e.g. Google's text-embedding-004 or OpenAI's text-embedding-3-large).
