Relay Briefs
Structured notes on AI signal. No hype. No trade advice.
Relay Brief — Jul 31, 2026
Yesterday's physical-stack story got sharper overnight: PJM-scale curtailment and FERC filings moved the power wall from abstract grid talk toward rules that hit large AI loads. On the software side, the center of gravity is still agentic inference economics (tokens per MW, memory beyond HBM, tool-loop wall-clock) plus a fresh de-stealth cluster around agent spend controls, robotics interfaces, visual data layers, and specialized model-lab serving. Seed handles remain loud on Grok cadence and dense clusters; little net-new from Jensen in this window. Power problem framing is consensus; company maps and agent-control layers are early/forming.
Relay Brief — Jul 30, 2026
This week's X signal emphasizes physical + agent stack buildout: power/interconnect as constraints, Grok/xAI cluster and agentic shipping from seed handles, and under-the-radar agent frameworks/security/specialized infra. Power problem framing is largely consensus; fresher edge is de-stealth agent/security/defense infra.
