## Topic
AI Infrastructure — physical layer (datacenter, optical, power, silicon stack)
under every AI model. Engineer-first; not investment advice.

## Update Frequency
- Tools / module markdown: weekly (Phase D generators)
- canonical_companies / business_signals / talent_signals: daily (V17 collectors)
- Maps: monthly

## Active Topic Hubs
- https://www.aiinframap.com/topic/optical-modules — Optical Modules (L3, 光模块): The interconnect layer that shapes every AI training cluster.

## Roadmap (Topics queued — not yet routable)
- Datacenter Power (L1, 数据中心电力): MW-scale power for AI clusters: where the electrons come from.
- Datacenter Cooling (L1, 数据中心散热): Direct-to-chip liquid is no longer optional past 100 kW/rack.
- AI ASICs (L2, AI 自研芯片): Hyperscaler silicon: TPU, Trainium, MTIA, Maia — and the merchant gap they create.
- HBM Memory (L2, HBM 高带宽内存): The bandwidth bottleneck that decides every training-cluster TCO.
- AI Networking (L3, AI 网络架构): Fat-tree, rail-optimized, dragonfly+: which topology survives at 100k GPUs?
- InfiniBand vs Ethernet (L3, InfiniBand vs 以太网): The ROCE/Ultra-Ethernet bet against NVIDIA's networking lock-in.
- Datacenter Buildout (L4, 数据中心建设): Site selection, construction lead-times, and the 18-month bottleneck.
