Microsoft to unveil Copilot 'super app,' new reasoning model, and Copilot Health at Build

Ahead of Build, The Verge reports Microsoft will unveil new AI models — including a new reasoning model — and a wave of Windows improvements, headlined by a Copilot "super app" that unifies Microsoft's fragmented Copilot assistants into a single interface. The consolidation addresses long-standing user confusion over Microsoft's sprawling, overlapping Copilot products.

Microsoft is also pushing Copilot Health, which connects wearables and wellness apps — starting with Apple Health — alongside medical records from over 50,000 US provider organizations, per Forbes. The healthcare push, led by Microsoft AI's Mustafa Suleyman (who teased "one last run-through before Build"), stakes a claim in clinical and consumer health AI, a high-stakes, heavily regulated arena.

The Build slate complements Microsoft's hardware narrative — Satya Nadella's framing of "unmetered intelligence to every home and every desk with Windows," tied to NVIDIA's RTX Spark — showing Microsoft pursuing AI across cloud, OS, hardware, and vertical apps simultaneously.

The sour note is developer sentiment: GitHub Copilot's shift from a flat monthly subscription to a new usage-based billing model drew vocal dissatisfaction, with many practitioners calling it the end of Copilot's "golden age." The backlash echoes a broader "tokenmaxxing" anxiety this week — as consumption-based pricing spreads, developers fear unpredictable bills for agentic workloads. Watch Build for whether Microsoft addresses the billing friction and how the new reasoning model benchmarks against GPT-5.5 and Claude Opus 4.8.
