Key Takeaways

  • Private Evals as Core IP: Every company should build private evaluation sets rather than relying on public benchmarks, which can be gamed. The true test of enterprise AI ownership is whether you can swap underlying models — from model A to model B — and still hill-climb on your private eval without leaking traces to vendors.
  • Hill-Climbing Scaffold Framework: Microsoft's MAI model strategy pairs a clean-lineage pretrained model with a hill-climbing scaffold that lets companies collect their own traces, build domain-specific reward functions, and create specialist agents from a generalist base — demonstrated by a 5B reasoning model outperforming larger models on private tasks.
  • Harness Architecture Over Model Selection: The enterprise AI stack should prioritize the harness — defining models, data, and tools in a closed loop — over chasing frontier model upgrades. Microsoft's multimodal harness, available via Azure Foundry, proved this when its security tool found vulnerabilities that dedicated security benchmarks missed.
  • Agent Traces as Balance Sheet Assets: Enterprise value will increasingly reside in accumulated agent traces — the recorded interactions between human workers and AI agents over time. These traces train company-specific veteran agents, functioning like tacit institutional knowledge that was previously impossible to capture or transfer systematically.
  • Pricing Model Evolution: Enterprise AI pricing will layer three tiers: per-user subscriptions bundling usage entitlements, consumption-based metering for agent workloads, and outcome-based pricing — though Nadella notes customers consistently revert from outcome pricing once they realize it means sharing upside, making flexible hybrid models the practical standard.

What It Covers

Satya Nadella joins a crossover episode of No Priors and Latent Space at Microsoft Build 2025, outlining Microsoft's ecosystem strategy around AI harnesses, private evaluations, MAI model training, enterprise agent deployment, data center expansion, and how every company can operate at the intelligence frontier.

Notable Moment

Nadella describes Azure's networking team as a concrete ambition model: rather than scaling headcount to manage exponential infrastructure growth, they built an agentic system named Miles to run fiber operations autonomously — then requested more token budget instead of more employees to sustain operations.

Episode Transcript

Please welcome Swyx Saragawa Alad Gil and chairman and chief executive officer of Microsoft, Satya Nadella. Thank you. Hello, Sat. I'm so excited to be here. Welcome to a crossover episode of no priors in lane space with Saan Adela. Congratulations on an amazing build. No. Thank you so much, and it's great to be with both of you. I listen to both of you or both the podcast all the time. It's great to be on it. Thank you so much. So you're just talking about these amazing announcements from across the Microsoft estate all morning for, I think, three hours. What is the what's the most important reflection or takeaway you have? I I'd say there are perhaps the biggest one for me is let's conceptualize this more as an ecosystem play as opposed to a single model or even a single platform. Right? Whenever I at least for me, having grown up at Microsoft, having seen whatever four major platform shifts, I fall into that camp where a platform is defined by fundamentally its ability to create more value about the platform versus what's captured in the platform. And so if you view what's happening right now, I think this morning's keynote was, how can any company, whether it's an AI native company or an traditional enterprise company, participate as a first class participant where they can point to AI create. Right? It's not that they don't use other people's AI. Of course, they will. But to me, what's the path? What's the recipe? How do I do it? What does the stack look like? What does the tooling look like? What is valuable? How do you do that? That's it. That's our job to do. Yeah. Ecosystem strategy is very complicated. Right? Because you end up building certain components, partnering for certain components, supporting them. You just announced this big suite of models. Tell us a little bit about the training strategy for Microsoft. So so the thing that we wanted to do with the MAI models was to build and as Mustafa talked about, first of all, a great lineage. Right? Starting with pretraining with very good data quality, doing all the aberrations, making sure because in in some sense, it's become even harder to build a clean lineage model. Yes. Because there's so much stuff out there that you truly need to ablate out to be able to have a fantastic pre trained model. In fact, that's one of the challenges of a lot of the open rate models is they look great on one benchmark or two, but they're not great on practice. So that's why, in fact, even in our FDEs are are pretty gone really excited about these MAI models because how the heck can a small five b model hill climb? And it goes back a little bit to what I think is ultimately the key thing to do, which is try to pursue finding that cognitive core. So to …
