HomeHarvey Launches Tenet Powered by Chinese Open-Source Kimi K3
American legal AI unicorn Harvey has unveiled Harvey Tenet, a specialized legal model built on Moonshot AI’s open-weight Kimi K3 through advanced post-training techniques. This milestone marks the first entry of a Chinese open-weight model into the training pipeline of a top-tier U.S. vertical AI firm.
Previously, Harvey powered its legal services using closed-source models from OpenAI and Anthropic, serving over 2,400 organizations and 200,000 lawyers, including numerous global corporate legal departments. With a current valuation of $11 billion and annualized revenue nearing $350 million, it stands as the highest-valued legal AI unicorn. The company is now raising funds at a valuation of approximately $15.5 billion. This shift from closed-source dependencies to a Chinese open-source foundation underscores growing practical confidence in open-weight models within specialized markets.
