A current, source-linked retrospective on the changes shaping AI infrastructure and technical delivery.
NEXUS BRIEFING · ISSUE 01 · OCTOBER 2026
Three years of shifts in AI infrastructure.
A concise retrospective on how model platforms, compute systems, and energy constraints have changed the questions technology leaders need to ask.
COVERAGE YEAR · 2023
Foundation models move behind managed APIs.
AWS announced general availability for Amazon Bedrock on 28 September 2023, making a managed set of foundation models and application-building capabilities available through AWS. The delivery lesson: choosing a model is one decision in a wider system of access, data handling, evaluation, cost, and operational ownership.
NVIDIA introduced its Blackwell platform on 18 March 2024, describing new GPU, networking, and resilience technologies. As AI infrastructure scales, planning reaches beyond accelerators to networks, facilities, deployment sequences, reliability, and the teams that will operate the system.
The International Energy Agency published its Energy and AI report on 10 April 2025, examining the growing links between data-center demand and electricity systems. For delivery teams, power availability, grid connections, cooling, procurement, and permitting can shape schedules as much as software choices.
