年。持续学习通过在新任务与知识上训练来强化模型，将带来对模型更新及既往数据访问的持续需求，并带动 HBM、服务器 DDR5 与 eSSD 等产品的存储用量。花旗预计，HBM 比特需求将于 2027 年同比增长 62% 至 752 亿吉比特，2028 年同比增长 69% 至 1270 亿吉比特。全球 DRAM 需求在 2027 年和 2028 年将分别同比增长 30% 和 35%，同期供应仅分别增长 19% 和 22%，供需比分别为 -8.7% 和 -9.7%。NAND 方面，2027 年和 2028 年需求将分别同比增长 29% 和 33%，超过供应增长 21% 和 25%，供需比分别为 -6.1% 和 -5.5%。花旗首选存储标的包括三星电子、SK 海力士、美光、Sandisk 和 Kioxia，分别对应持续学习带来的存储短缺、HBM 与服务器 DDR5 需求、DRAM 供不应求以及高密度 eSSD 与 NAND 供应趋紧等逻辑。

Kimi K3 为代表的开源模型，在 Artificial Analysis Intelligence Index 综合得分上仅落后 Anthropic Fable 5 三个点，但成本仅为其约 30%。METR 测算显示，最强闭源模型可稳定完成时长约 12 小时的人类专家任务，而最强开源模型目前可靠完成约 7 小时任务，预计约 4 个月后开源模型将追上当前闭源水平。Mozilla 认为，大多数组织应默认采用开源模型，仅在专业、高强度检索和长上下文等场景为闭源模型支付溢价。付费购买前沿人工智能模型，成本是普通购买的 5 倍，却能获得 4 个月的先发优势。
