From LLM Wrapper to Enterprise Operating System

How Harvey AI Works: RAG, Fine-Tuning, and Hallucination Reduction
Unlike general-purpose models like GPT-4 or Claude, Harvey uses retrieval-augmented generation (RAG) infrastructure to ground every legal response in actual case law, statutes, and regulations — significantly reducing the risk of hallucinated citations.
Retrieval-Augmented Generation
Every query is cross-referenced against verified legal databases before generating a response, ensuring citations link to real case law and statutes.
Domain-Specific Fine-Tuning
Harvey's models are trained on legal corpora — contracts, briefs, opinions, regulatory filings — not general web data. This produces higher-quality legal reasoning.
Jurisdiction-Specific Context
Coverage across 60+ countries with awareness of both civil law and common law systems. Models understand local procedure rules and regulatory frameworks.
Enterprise-Grade Security
SOC2 Type II and GDPR compliant. Data isolation ensures no client data leaks across firm boundaries. Meets BigLaw's strictest security requirements.
