Nadella argues firms must capture and own AI value themselves, as alignment and trust can't be assumed from frontier model providers.

Alignment no longer self-solving: Nadella says he used to believe alignment would "fall out" of scaling laws but now thinks it's a harder, separate science problem requiring work at pre-training.
Zero-trust over AI safety: Microsoft is building Agent 365 and a 'Foundry Control Plane'-style system giving every AI agent an identity, logging all tool calls and chain-of-thought, to contain unaligned agents.
Chain-of-thought is unreliable: Nadella states CoT can be unfaithful and models could learn to hide reasoning, pushing him to favor standardized, inspectable, auditable reasoning traces — possibly via more open weights.
Every firm needs owned intelligence: Nadella argues firms must capture AI value via private evals, context, and fine-tuned weights rather than leaking it to model providers, citing Unilever's shift from a frontier model to Microsoft's own MAI model for trade-claims processing to cut cost.
Horizontal stack, not monopoly: He sees competition deepening at every layer (silicon, systems, models, apps) rather than one vertically integrated winner, though he calls MAI models 'licensed weights' rather than open or closed.
$100B training runs tied to GDP: Nadella frames massive training spend as a function of world GDP growth and R&D budgets, and hopes AI can meaningfully inflect the ~2%/year global growth rate.

Deep dive

Trust architecture over AI safety

Nadella separates the unresolved science of AI safety from an engineered "zero trust" containment system that can be deployed regardless. Because capable models may not be well-aligned, Microsoft is building Agent 365 and a companion perception/control layer giving every agent an identity, logging all tool calls, model calls, and chain-of-thought, with tamper-proof policy enforcement to contain malfunctioning agents before harm occurs. He stresses chain-of-thought itself is "not reliable" and can be unfaithful, and pushes for CoT to be rendered in English, inspectable by multiple models, and standardized across trusted partners — a requirement he says could itself drive more open-weight releases if closed providers resist transparency.
