[2026-07-20] Kimi K3 发布与市场冲击
来源:Fable 5 × CursorBench / Kimi K3(2026-07-17)。
2026-07-17 发布 Kimi K3——相较 Kimi K2(1T / 128K)大幅升级:
| 维度 | Kimi K3 |
|---|---|
| 总参数 | 2.8 万亿(2.8T) |
| 上下文 | 100 万(1M)tokens |
| 智能指数(Artificial Analysis) | 57(接近 GPT-5.5 / Claude Opus 4.8) |
| 单任务成本 | $0.94(约 Opus 4.8 一半) |
| 前端代码竞技场 | 1679 分(第一) |
| API 定价 | 3 输入 / 15 输出(每百万 token) |
| 完整权重 | 最晚 2026-07-27 发布 |
市场冲击:发布当晚催化全球 AI/半导体股抛售(摩根大通称”DeepSeek 2.0”,高盛称”去杠杆事件”)。核心论断:单纯扩大预训练算力不再是获得领先能力的唯一路径,架构/数据质量/RL/后训练效率重要性上升。详见 Kimi K3 与 Scaling Law 之争。
