The hardware story behind frontier AI
Compute clusters, data centers, GPU supply, power deals, and capex — the physical layer that decides which labs can train tomorrow's frontier and at what unit cost. Editorial briefs synthesize the data; signals below are the atomic facts they're built on.

The CoWoS bottleneck: why GPU supply still gates 2026 model roadmaps
Every Blackwell, Ironwood, and Trainium2 chip flows through one TSMC packaging line. Capacity doubled in 2026 — and every frontier lab is still constrained.

Anthropic's two-cloud bet: why Trainium plus TPU changes the math
Custom silicon on two hyperscalers gives Anthropic the lowest unit cost in the frontier — and the biggest single-vendor risk.

Amazon's $8B Anthropic investment locks in Trainium as primary training chip
Amazon committed an additional $4B to Anthropic in November 2024 on top of an earlier $4B — total $8B — with the condition that Anthropic adopt AWS Trainium2 as the primary training chip for future Claude models. The deal underwrites Project Rainier and makes Anthropic the anchor tenant for AWS's custom silicon roadmap.
