AI Signals and Reality Checks 推理正成为路由问题 推理正在变成一个路由问题 重点不在于 AI 实验室和云厂商正在寻找 Nvidia 的替代方案；重点在于，推理正在变成一个工作负载路由问题，因为内存带宽、功耗边界、封装产能、延迟目标和软件支持，正在决定哪些模型调用在经济上可行。 最新信号不是某一个单独公告，而是一组信号同时出现。5 月 21 日，AMD 宣布将在台湾产业生态投入超过 100 亿美元，用于扩大策略合作伙伴关系，并提升面向 AI 基础设施的先进封装产能，其中包括 Helios 机架级平台和 Instinct MI450X 的部署计划。同一天，AMD 还宣布下一代 EPYC “Venice” CPU 已经在台积电 2 纳米制程上进入量产爬坡，并明确把 CPU 描述为 AI 数据移动、网络、存储、安全和系统编排的协调层。
AI Signals and Reality Checks Inference Is Becoming a Routing Problem Inference Is Becoming a Routing Problem The important thing is not that AI labs and cloud providers are looking for Nvidia alternatives; it is that inference is becoming a workload-routing problem because memory bandwidth, power envelopes, packaging capacity, latency targets, and software support now decide which model calls are
AI Investment Frontier 气候 Alpha 需要异构天气模型 A new SSRN paper uses machine learning to estimate firm-level weather impacts and finds investor underreaction around earnings. The useful lesson is not a climate trade, but a better event-risk architecture.
