Microsoft Build 2026 | Opening Keynote

Key Concepts

• Frontier Intelligence Ecosystem: A shift from individual models to a collaborative, agentic stack where developers build value on top of platforms.
• Agentic Workflows: Autonomous systems that reason, generate code, and act across files, devices, and networks.
• Unmetered Intelligence: The concept of ubiquitous AI compute available locally on devices (Edge) and in the cloud.
• Hill-Climbing Machine: A system that continuously improves agent performance against specific objectives, private evaluations, and institutional data.
• Microsoft Foundry: A unified platform for building, deploying, and governing agentic applications.
• MXC (Microsoft Execution Containers): OS-native policy layer for isolating and containing agent actions.
• Project Solara: An ecosystem of purpose-built, agent-first hardware devices.
• Microsoft Discovery: An agentic loop integrating models, simulation, and automated labs for scientific research.

1. The AI Stack: Infrastructure to Runtime

The conference outlined a multi-layered AI stack:

• Ubiquitous Compute Fabric: Spanning from edge devices (NPUs/GPUs on Windows) to massive cloud data centers.
• Emerging Layer: Models, context, and tools.
• Runtime: Deployment environment for agents and applications.
• Governance/Security: Integrated compliance and policy enforcement (e.g., MXC).

Key Hardware/Infrastructure:

• Surface RTX/DevBox: A "dream machine" for developers featuring 1 Petaflop of AI compute and 128GB of unified memory.
• Data Center Innovation: Microsoft has added more data center capacity in the last 18 months than in the previous decade. New designs (e.g., "Fairwater") utilize liquid cooling and closed-loop water systems to achieve near-zero water consumption.
• Silicon Co-design: Collaboration with NVIDIA (Grace Blackwell) and AMD (MI300) to optimize tokens-per-dollar-per-watt. The Cobalt 100 CPU is specifically designed for cloud-native agent workloads, delivering 33% lower latency and 23% higher throughput.

2. Windows as an Agentic Platform

Windows is being transformed into a first-class environment for local AI:

• Local AI: Features like Outlook summarization and Teams super-resolution run locally.
• Developer Tools: Introduction of an intelligent terminal with GitHub Copilot, 75+ command-line utilities (grep, sed, etc.), and native Homebrew support.
• Security: MXC (Microsoft Execution Containers) provides process-level and session-level isolation, preventing agents from performing unauthorized actions (e.g., deleting files).

3. Project Solara: Agent-First Devices

Project Solara aims to move agents beyond the app frame into purpose-built hardware:

• Stationary Devices: Ambient devices for desks (MediaTek silicon) that provide frictionless access to M365 Copilot.
• Wearables: Lightweight badges (Qualcomm silicon) for on-the-go agent interaction, demonstrated in healthcare scenarios for hands-free documentation and patient care.

4. Microsoft IQ: The Context Layer

Agents are only as effective as their context. Microsoft IQ unifies three data tiers:

• Web IQ: Model-agnostic, MCP-native web grounding for fresh, verifiable data.
• Fabric IQ: A living model of business operations using ontologies and live telemetry.
• Work IQ: Grounding in organizational procedures (SharePoint/Teams) that updates automatically as policies change.

5. Frontier Tuning and Scientific Discovery

• Frontier Tuning: A methodology where organizations use their own private data, rubrics, and Reinforcement Learning Environments (RLEs) to "hill-climb" model performance. This allows companies to build a proprietary "moat" by continuously improving agents on their specific workflows.
• New Model Family: Seven new models were announced, including MAI Thinking 1 (reasoning model) and MAI Code 1 Flash (inference-efficient coding model).
• Microsoft Discovery: An agentic loop for scientific research. It automates hypothesis generation, simulation, and lab execution. A case study was presented on using this to discover proteins for plastic recycling.
• Quantum Computing: Announcement of Majorana 2, a topological qubit approach achieving 20-second lifetimes—a 1,000x improvement over Majorana 1—enabling scalable, reliable quantum computation.

6. Synthesis and Conclusion

The core argument presented is that the "AI era" is not about a single model, but about the Frontier Intelligence Ecosystem. By moving from "consuming" models to "participating" in the frontier—through private evaluations, RLEs, and agentic security—developers can build systems that compound institutional knowledge. The ultimate goal is to ensure technology serves human agency rather than concentrating power, with a focus on "humanist superintelligence" that prioritizes human well-being and scientific progress.
