Harvey rebuilt on Moonshot's Kimi K3 and its margins turned positive again.
Usage fees stacked on base subscriptions pushed Harvey's gross margin from about 50 percent to minus 50 percent before an August rebuild on Moonshot's Kimi K3 fixed it. The cheapest compliant seats for that Chinese model are American inference hosts running chips export controls keep from China.

A $15.6 billion startup losing money on every query
Harvey, the legal-AI company valued at $15.6 billion, watched its gross margin slide from about 50 percent at the start of the year to minus 50 percent by June, after a March update to its agents sent usage soaring, according to a person familiar with the numbers 1. Token consumption is up twentyfold this year, the company says 1. The rented models did the damage: OpenAI and Anthropic now bill enterprises for usage on top of base subscription fees, pricing that had already burned Uber's full-year AI budget by April 1.
The escape route runs through Beijing
Harvey's August fix is a model post-trained on Kimi K3, the 2.8-trillion-parameter open-weight release from China's Moonshot AI, and its margins turned positive again 1. Abridge now builds on Nvidia's open weights, Decagon routes 80 percent of customer queries through its own models, and Ramp, which raised $750 million in June, is weighing training for the first time 1. The quiet collectors sit below the headlines. Modal, Fireworks AI and Baseten host Kimi K3 at roughly $3 per million input tokens and $15 per million output, on Nvidia GB300 and AMD MI350X hardware that export controls keep from Chinese firms, sold with zero-data-retention terms and US endpoints 2. No public account names Harvey's host; the layer collects whoever defects.
US-hosted Kimi K3 undercuts Anthropic's flagships on every token

"Cosplay," until it saves the margin
Menlo Ventures partner Matt Kraning calls most custom-model talk "a lot of cosplay," and Salespeak abandoned its own model-building effort after seeing no major advantage 1. US security agencies accuse Moonshot of distilling American models, and Rogo has had to walk large customers past their hesitation about Chinese weights 1. Even Anthropic's own investor-forum slide concedes Harvey still needs Opus for its hardest tasks 1. The frontier stays rented; the volume work leaks.
Cut off the week of the summit
OpenAI will end SpaceX-owned Cursor's model access on 12 November, citing past contract violations by Elon Musk's companies, weeks after investors floated a $1.2 trillion valuation ahead of an IPO expected next year 45. Nothing argues for hedging harder than a supplier who can quit. Xi Jinping meets Donald Trump in Washington this week with artificial intelligence on the agenda and Sam Altman and Jensen Huang at the state dinner 6. Watch whether the compliant American wrapper around Beijing's biggest open model survives the summit.
