【中文】K3 明日开源:1.4TB 权重的“部署经济学”,许可证仍是悬念

Kimi K3 开放权重定于明日(7月27日)发布,将是有史以来最大的开源权重投放:2.8 万亿参数 MoE(每 token 仅激活约 500 亿)。但“开放”不等于“人人可用”——MXFP4 四比特精度下权重就要约 1.4TB 高速显存(16 位则是 5.6TB),需要 Nvidia Blackwell 或 AMD MI400 级别的多卡服务器,八张 192GB 卡的顶配单机也只是勉强装下。分析指出:这个体量的开源不是把能力推向边缘,而是把能力交给“养得起 1.4TB 常驻显存”的推理服务商、大企业与云厂商。另一个关键悬念:月之暗面至今未公布许可证条款,商用范围、下游训练许可全部待定。

【EN】K3 Opens Tomorrow: the 1.4TB Deployment Economics, and a Still-Missing License

Kimi K3's open weights arrive tomorrow (July 27), the largest open-weight release ever: a 2.8-trillion-parameter MoE activating only about 50B parameters per token. But open won't mean accessible: the weights need roughly 1.4TB of fast memory even at MXFP4 4-bit precision (5.6TB at 16-bit), demanding multi-accelerator nodes with Nvidia Blackwell or AMD MI400 — a top-end eight-way 192GB server barely fits them. As one analysis puts it, weights at this scale don't push capability to the edge; they hand it to whoever can afford to keep 1.4TB loaded and busy: inference providers, large enterprises, clouds. The other open question: Moonshot still hasn't published license terms, leaving commercial use and downstream training rights undefined.
