2026年5月:光纤内存告急,AI淘金者不如卖铲人

from AI观测站-AI Observatory

2026年5月,AI产业的焦点正从模型能力本身转向其基础设施瓶颈。NVIDIA与康宁签订的32亿美元光纤协议,以及美光2026年HBM产能的全面售罄,都表明数据中心的互联和内存供应正成为新的制约因素。这预示着AI的价值创造正在从模型公司向基础设施公司转移,模型竞赛也开始侧重于“自主时长”这一新维度。AI数据中心光互联重建NVIDIA与康宁签署32亿美元协议,计划提升光纤产能50%,光模块产量1000%。Veeco获得2.5亿美元订单,用于生产800G/1.6T光收发器设备。AI数据中心互联瓶颈从“算力不够”转向“带宽不够”,推动从“电互联”到“光互联”转变。这32亿美元是NVIDIA的护城河,让其DGX集群拥有竞争优势。HBM内存市场“通胀”美光宣布其2026年HBM产能已全部预售完毕。全球内存市场预计将从2025年2163亿美元增至2026年6333亿美元,涨近三倍。HBM因制造复杂、产能受限,成为AI部署的第二大瓶颈,导致“内存通胀”。这影响AI初创公司的推理成本,并使三星和SK海力士获得定价权。模型能力转向“自主时长”Anthropic Claude Mythos预览版在METR基准上“时间跨度”超第二名2倍。OpenAI的实时语音API和本地运行的百万token编码代理(如Garry Tan提到的)预示“代理式AI”发展。模型竞赛焦点从传统基准分数(如MMLU)转向模型自主完成多周期任务的能力。AI产业价值创造重心转移AI产业瓶颈正从GPU、封装,逐步转移到光互联和HBM内存。基础设施扩张(24-36个月)慢于模型能力提升(12-18个月)的速度,形成结构性矛盾。未来AI基础设施公司(如康宁、美光)的市值增速,可能超越模型公司(如OpenAI、Anthropic)。
