Harvey Unveils Deep Research AI for Faster, Transparent Legal Analysis

Harvey Launches Deep Research for Legal

27th June 2025

Harvey has introduced Deep Research for Legal, leveraging OpenAI’s latest research capabilities to create advanced legal research agents. These agents are built to support top law firms and enterprise legal teams by combining OpenAI’s new API with Harvey’s legal reasoning systems.

This integration delivers explainable, thorough, multi-step, and multi-source analysis that can handle complex legal questions with clarity and precision.

How Deep Research Works

A short 8-minute video from Harvey demonstrates the AI in action. What stands out is the quiet efficiency: the AI scans through numerous relevant sources, evaluates their applicability to different aspects of a query, retains useful information, discards irrelevant details, and continues this process across many documents.

Most of the video shows the AI working steadily—compressing what might take human associates days into minutes. The final output includes a detailed answer supported by tabular data, providing a clear and well-organized response.

This approach offers transparency by showing the sources consulted, which helps verify accuracy and builds trust. Watching the AI ‘think’ slowly and methodically reassures users that it’s delivering a properly reasoned legal analysis rather than a quick guess.

Is This a Significant Development?

The capability to perform days’ worth of legal research in minutes could notably improve efficiency for legal teams. However, accuracy testing remains crucial. The inclusion of source references provides a solid foundation for validation.

CEO Winston Weinberg confirmed plans to integrate Deep Research across Harvey’s platform, including Assistant, Vault, and Workflows, expanding its utility for legal professionals.

Recent Funding and Growth

This launch follows Harvey’s announcement of a $300 million funding round, valuing the company at $5 billion. The investment will support international expansion and customer support across 53 countries.
