News Summary

• Harvey has launched Tenet, its first proprietary model for legal work.
• It is post-trained on Kimi K3, the open-weight model from Chinese startup Moonshot.
• The company is backed by OpenAI, whose models Tenet is designed to displace inside Harvey’s own product.
• The commercial logic is unsubtle.
• Every model call Harvey makes is an invoice from a rival, and owning the engine turns a variable cost into a fixed one.
• For a European buyer the AI Act is the next question.
