Legal AI unicorn Harvey adopts Chinese open-source models to reduce costs

According to Huxiu, Harvey, a legal AI unicorn valued at $15.6 billion, is re-evaluating heavy reliance on AI giants and moving toward open-weight/open-source model ecosystems to cut costs as compute and usage surge push gross margins from about 50% to -50% by June. In August, Harvey launched its first self-developed model powered by Kimi K3 from Moon of the Dark Side, aiming to reduce external dependencies amid IPO activity by OpenAI and Anthropic. Sequoia Capital and General Catalyst are backing this tech shift, which could divert substantial revenue from the giants.
