At Build 2026, Microsoft unveiled a developer platform update themed 'Be Yourself,' centered on giving developers true ownership of intelligence—through the Microsoft IQ context layer, the MAI in-house model family, and the Scout personal agent, building a full-stack ecosystem from local to cloud, diverse in models and open.
At Build 2026, Microsoft introduced Microsoft IQ, a new context layer designed to ground agents in world knowledge and enterprise knowledge. This layer includes multiple components: Work IQ (workplace intelligence layer capturing how work gets done in M365), Fabric IQ (semantic foundation for structured business data), Foundry IQ (integrating enterprise knowledge with real-time web), and the newly released Web IQ (AI-first web search stack, 2.5x faster than the next best option). The Work IQ API will be generally available on June 16, providing programmatic access.
Microsoft emphasizes that as model capabilities improve, the differentiator for organizations is no longer access to intelligence but ownership—how to make expertise, data, and work patterns a system of continuous learning. The goal of Microsoft IQ is to enable companies to own their agents, rather than returning value to consultancies or model makers.
Microsoft's AI Super Intelligence team released seven new in-house models, among which MAI-Thinking-1 is Microsoft's first reasoning model, with 35 billion active parameters and a 256K context window, trained from scratch on enterprise-grade clean data without distillation. In blind tests, independent evaluators preferred it over Sonnet 4.6, and on SWE Bench Pro, its coding ability matched Opus 4.6. The model is now in private preview on Foundry.
MAI-Image-2.5 and its flash variant are Microsoft's first models supporting both text-to-image (ranked 3rd on Arena AI leaderboard) and image-to-image (ranked 2nd, surpassing Nano Banana 2), already integrated into PowerPoint and OneDrive, and available on Foundry with market-leading cost-performance. Additionally, MAI Transcribe 1.5 supports high-accuracy transcription in 43 languages, and MAI-Voice-2 with its flash variant have also been released.
Microsoft announced Microsoft Scout, a personal work agent based on OpenClaw and Work IQ, capable of proactively handling meeting preparation, schedule conflicts, and daily tasks without user instructions. Currently available to Frontier customers, it will roll out more broadly in the future. Scout embodies a new form of 'always-on' autonomous agent.
On the developer tools front, Windows receives new developer configurations, offering more flexible development environments, a frictionless intelligent terminal, a local agent sandbox, and new WSL features. Microsoft emphasizes 'Windows for developers,' aiming to let developers build in their own chosen way, covering the full stack from chip to operating system, development tools to cloud.

Model performance comparisons (e.g., blind test preferences, benchmark rankings) are claimed by Microsoft and should be treated with caution.
The core narrative of Microsoft Build 2026 is: achieving intelligence ownership through Microsoft IQ, providing high-performance options through MAI in-house models, and giving developers more control through Scout and Windows updates. This marks a shift in Microsoft's AI platform strategy from simply offering models to building a developer-centric ecosystem that is model-diverse and context-rich.
