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.

xAI Colossus 2: targeting 1M GPUs across Memphis + new Mississippi site
Colossus 2 — xAI's expansion target — aims for 550k Blackwell-class GPUs (GB200/GB300) in 2026, scaling toward 1M total accelerators by year-end. A second 2GW campus in DeSoto County, MS, is under construction to host the bulk of the buildout. Power deals announced with the Tennessee Valley Authority and Mississippi Power.

xAI Colossus: 200k H100 GPUs in 122 days at the Memphis ex-Electrolux site
xAI brought up its first Memphis training cluster, "Colossus", in 122 days — a build cadence unprecedented in the industry. The initial buildout was 100k H100s; xAI doubled it to 200k by early 2025 by adding H200s. Power was bridged with on-site mobile gas turbines while Tennessee Valley Authority capacity caught up. Colossus trained Grok 3 and is currently training Grok 4 successors.
