Moonshot 把 2.8T 参数的金刚级模型权重大方放出来了，就是商用门槛卡得严——大厂做 MaaS 得单独谈。价格倒很统一，OpenRouter 上多家同价。
Moonshot AI 兑现承诺，于 7 月 27 日发布 Kimi K3 的完整权重，参数规模达 2.8 万亿，Hugging Face 上文件大小约 1.56TB。与 K2 使用的“修改版 MIT 许可”不同，K3 不再自称 MIT，而是规定月活超 1 亿或月营收超 2000 万美元的 MaaS 业务需与 Moonshot 另行签约。OpenRouter 已上线 K3，来自 7 个提供商，定价均为每百万输入 token 3 美元、每百万输出 token 15 美元。

moonshotai/Kimi-K3 As promised earlier this month , Moonshot have released the weights for their excellent 2.8 trillion parameter Kimi K3. They're a hefty 1.56TB on Hugging Face. Kimi introduced their own janky modified version of the MIT license with K2 back in July 2025. That license just added this paragraph requiring attribution beyond a certain size of commercial entity: Our only modification part is that, if the Software (or any derivative works thereof) is used for any of your commercial products or services that have more than 100 million monthly active users, or more than 20 million US dollars (or equivalent in other currencies) in monthly revenue, you shall prominently display "Kimi K2" on the user interface of such product or service. The K3 license no longer calls itself "modified MIT" and goes further, requiring a separate agreement with Moonshot for large "Model as a Service" businesses: If the Licensee or any of its affiliates operates a Model as a Service business, and the aggregate revenue of the Licensee and its affiliates exceeds 20 million US dollars (or the equivalent in other currencies) in total over any consecutive 12 months, the Licensee must enter into a separate agreement with Moonshot AI before using the Software or its derivative works for any commercial purpose. To Kimi's credit, they make no attempt to describe this as an "open source" license in their own materials, consistently using the term "open weight" in its place. OpenRouter is already offering K3 from 7 providers , most of which are at the same $3/million input and $15/million output as Moonshot AI themselves.
