Following Google I/O last week, the Microsoft Build 2026 Developer Conference also kicked off at the Fort Mason Center in San Francisco.
from7 self-developed MAI modelsarriveScout, a personal AI assistant based on OpenClaw,fromSurface mini development machine equipped with NVIDIA chiparriveProject Solara, an operating system designed specifically for AI agents, Microsoft is accelerating the construction of a complete AI ecological closed loop.
1. MAI-Thinking-1: Microsoft’s first inference model unveiled
The biggest technical highlight of this build is that Microsoft released it in one go7 new MAI (Microsoft AI) self-developed models, covering multiple directions such as reasoning, code generation, images, speech, and transcription.MAI-Thinking-1, is the first AI model in Microsoft history with advanced reasoning capabilities.
MAI-Thinking-1 has35 billion active parametersand128K context window, Microsoft said its performance "matches leading models" on software engineering benchmarks.Trained entirely using cleaned raw data, not distilled from any third-party models——This seems particularly hard-core in the current atmosphere of "mutual distillation" in the AI circle.
In addition, Microsoft also released MAI-Image-2.5 (image generation), MAI-Voice-2 (speech synthesis), MAI-Transcribe-1.5 (voice transcription) andDesigned forGitHub CopilotOptimized MAI code model.

- MAI-Image-2.5/MAI-Voice-2/MAI-Transcribe-1.5: multimodal matrix
2. Microsoft Scout: Your 24/7 AI personal assistant
Microsoft also launched aPersonal AI assistant with built-in OpenClaw - Microsoft Scout.An AI agent that is always online and can perform tasks independently in the background.
Scout can be connected to Microsoft 365 applications such as Outlook, OneDrive, and Teams to help corporate employees automatically manage calendars, process reimbursements, draft emails, etc.It’s a true personal assistant, nothing like a chatty AI—you might get a call from it."
Scout is currently available as a desktop preview to Frontier customers in the United States.A series of “Autopilot” agents, each with an independent identity.
3. Surface RTX Spark Dev Box: a mini host customized for AI developers
In terms of hardware, Microsoft delivered an eye-catching device:Surface RTX Spark Dev Box.128GB unified memory, can be run locallyModels with up to 120 billion parameters.
This device is pre-installed with a streamlined version of Windows 11 Pro (default dark mode, no widgets) and is designed for local training and inference of AI models.
4. Project Solara: A “new system” for AI agents
Microsoft also showed off an interesting concept product:Project Solara——A lightweight operating system based on Android, specially used to drive various AI intelligent devices.
Microsoft developed this platform in partnership with Qualcomm and MediaTek.
5. Windows embraces developers: Linux experience + AI terminal
Microsoft also announced a series of Windows 11 improvements for developers:Native Coreutils command line tool(Goodbye MinGW/Cygwin), WSL built-in Linux container support, and brand newIntelligent Terminal——An AI-enhanced terminal that can understand the developer's intentions and proactively provide code context.
At the same time, Microsoft releasedMicrosoft Execution Containers (MXC)The security sandbox allows AI agents such as OpenClaw to run safely on Windows - without accidentally deleting your files.
6. Majorana 2 Quantum Chip: The countdown to practical quantum computing has begun
The final “Easter egg” comes from quantum computing.Majorana 2——The next generation of topological quantum chip, the stability of qubits is improved compared with the previous generation1000 times.A truly practical quantum computer is expected to be built in 2029.
Summary: Microsoft’s AI “Declaration of Independence”
Looking at the entire Build 2026, the core signals are:Microsoft is transforming from "a reseller of OpenAI" to "a platform company with a complete AI technology stack".
For users and developers, this means that the Windows ecosystem will be deeply AI-based in the future - your computer will not only run programs, but will also have AI agents actively help you work.
