U.S. $11 Billion Legal AI Unicorn Trains Its Own Model, Built on China's Kimi K3

Beating AI Newsflash: U.S.-based legal AI company Harvey has launched its first proprietary legal model, Tenet, which is built on the open-source model Kimi K3 from Moonlight Shadow. The model has undergone fine-tuning specifically for legal reasoning. Harvey is currently valued at $11 billion, with total funding exceeding $1 billion. Previously, it primarily relied on general-purpose models from companies like OpenAI and Anthropic. This marks the first time Harvey has developed its own legal model. To train Tenet, Harvey enlisted lawyers to create virtual disputes and case materials, then scored the model's legal reasoning outputs, using this data to further train Kimi K3. Harvey claims that Tenet has reached the level of top-tier general-purpose models in major legal benchmarks, while also being more cost-effective. However, specific benchmark scores have not yet been disclosed, and Tenet has not been officially launched. In the future, Harvey plans to allow different law firms to further train their own exclusive legal models based on Tenet. [Original Article Link]
