Microsoft Build 2026: What we actually know about the new AI models
The company promises new reasoning capabilities and a Copilot 'super app,' but the technical details remain frustratingly sparse.

A smaller venue in San Francisco. A company reshuffling its entire business around AI. And, if the reporting is accurate, new AI models that Microsoft hopes will matter to developers who have grown increasingly skeptical of the company's direction. That's the setup for Build 2026, which kicks off June 2nd with a keynote that promises to address what The Verge calls "a more pivotal moment" than any Build conference in recent memory.
I want to be precise about what we actually know versus what we're speculating about, because the pre-conference reporting conflates the two in ways that frustrate me. Here's what sources have told The Verge: Microsoft will announce new AI models in Windows, a new reasoning model from Microsoft AI, and something called a Copilot "super app." There's also mention of "agentic OpenClaw-like tools," which is an interesting framing that suggests Microsoft is positioning its agent capabilities against whatever OpenAI has been doing with its own agentic frameworks.
What we don't know is substantially more important. The phrase "new reasoning model" could mean almost anything. Is this a novel architecture? A fine-tuned variant of an existing model with chain-of-thought prompting baked in? Something built on top of OpenAI's o-series models, or a genuinely independent Microsoft AI effort? The reporting doesn't say, and I suspect that's because Microsoft hasn't said. This is the problem with pre-conference coverage: we're working with carefully managed leaks designed to generate interest, not technical documentation.
It's worth noting that Microsoft's relationship with reasoning models has been, to put it charitably, complicated. The company has access to OpenAI's models through its partnership, but it has also been building its own AI research capabilities through Microsoft Research and the Microsoft AI division. When they say "Microsoft AI" developed a reasoning model, that could mean anything from a from-scratch training effort to a sophisticated prompting system layered on existing foundations. I know I'm being picky here, but these distinctions matter enormously for understanding what's actually new.
