  "account": "OpenAI-backed legal technology firm Harvey has transitioned to using Chinese open-weight model Kimi K3, developed by Beijing-based company Moonshot AI. This shift reflects a growing trend among Western tech companies to adopt Chinese open-weight systems due to escalating costs. Harvey's new model, Harvey Tenet, is post-trained on the open-weight Kimi K3 base. The company claims this approach has achieved \"state-of-the-art\" performance in complex legal tasks. Harvey, which serves major international law firms and enterprise clients, had previously specialized in customizing closed proprietary models from US leaders like Anthropic, OpenAI, and Google for legal applications. The pivot to open-weight models allows for post-training systems on specific industry or corporate data for higher accuracy and lower inference costs. AI policy researcher Simon Hedlin highlighted that Harvey's move is a prime example of the capabilities of open-weight models, enabling developers to tailor systems to specific tasks. Harvey's research over the past six months has focused on building \"frontier legal intelligence using open-weight models\" to help law firms create and deploy specialized models. Trained on extensive legal datasets, Harvey Tenet surpassed both its underlying base model and other US frontier systems such as Fable 5 and GPT-5.6 Sol in various complex legal agentic tasks, while also improving cost efficiency. Open-source models like Nvidia's Nemotron series are now used by 40% of AT&T's employee AI queries, according to a report by The Information. Despite this trend, Harvey's spokesperson noted that the company is still evaluating the potential risks and assessing options from Chinese firms, including DeepSeek and Moonshot AI, the creator of Kimi K3.",
  "summary": "A US artificial intelligence start-up backed by OpenAI has built its first in-house model on Chinese lab Moonshot AI’s Kimi K3, highlighting a growing shift by Western tech firms towards Chinese open-weight systems amid soaring development costs. San Francisco-based legal tech provider Harvey, whose high-profile backers also include Sequoia Capital and Andreessen Horowitz, said on Thursday that…",
