# 月之暗面发布2.8万亿参数Kimi K3模型权重，许可证条款趋严

## AI 点评

> 这篇博客精准点出了大模型开源运动中的关键转折：K3用法律语言告诉行业，超大模型可以公开权重但绝不放弃商业控制权。对AI创业公司和大型云厂商而言，理解这种‘分层的开放’比堆参数更重要。

## 速览

月之暗面兑现承诺，在Hugging Face上发布了2.8万亿参数的Kimi K3模型权重，大小达1.56TB。与K2的“修改版MIT”不同，K3许可证不再冠以“开源”之名，而是要求月活跃用户超1亿或月收入超2000万美元的MaaS企业需与月之暗面单独签署商业协议。OpenRouter已上线K3服务，定价与官方一致。

## 关键点

- Kimi K3 拥有2.8万亿参数，权重文件1.56TB，已开放下载
- 新许可证不再自称“修改版MIT”，而是要求大型MaaS企业单独签约
- 月之暗面未使用“开源”表述，改用“开放权重”
- OpenRouter已聚合7家供应商提供K3推理服务

## 全文

moonshotai/Kimi-K3 As promised a few weeks ago, 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 those larger companies: 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.
