OpenAI-backed legal tech firm pivots to Chinese Kimi K3 open-weight model
Harvey, an OpenAI-backed legal tech firm, now uses Chinese Kimi K3 open-weight model for its new Harvey Tenet system, marking a shift from proprietary models.Summary
Harvey, a San Francisco‑based legal technology provider backed by OpenAI, Sequoia Capital and Andreessen Horowitz, has built its first in‑house model, Harvey Tenet, by post‑training the Chinese Kimi K3 open‑weight model from Moonshot AI. The system achieved state‑of‑the‑art performance on complex legal tasks, marking a shift away from the proprietary models previously used by the firm. The move highlights a growing trend among Western tech firms to adopt Chinese open‑weight models as development costs soar, allowing developers to fine‑tune models on industry‑specific data for higher accuracy and lower inference expenses. AI policy researcher Simon Hedlin noted that Harvey's pivot exemplifies how open‑weight models enable such post‑training for specialized applications.
