Windows to get built-in AI models: what Microsoft is preparing for Build

At Build in San Francisco, Microsoft will announce three main initiatives: new AI models built directly into Windows, a reasoning model from Microsoft's own lab, Microsoft AI, and a reimagined Copilot as a universal "super app". It is a desperate attempt to win back the developer trust the company has lost in recent years.

What is changing in Windows

Microsoft is integrating AI models at the operating system level. This is not just another chatbot in the corner of the screen: it is a fundamental rework of how Windows interacts with code, text and visual content. The built-in models will be able to analyze the context of running programs and offer help without requiring you to switch to a separate app.

A developer opens their code editor, and the AI is already ready to help, with the full context of the project in view. This matters especially for developers: the tools will be integrated directly into the development environment (IDE). There is no need to open a browser or a chat window, because all the help is where you work.

Reasoning model: an assistant that thinks

Microsoft will announce its own reasoning model. It is not just a language model for generating text but a tool capable of more complex logical inference and step-by-step problem solving. Such models handle multi-step problems better, from debugging a frozen application to designing an optimal algorithm for working with data. They do not just produce an answer; they show their reasoning.

For developers, this offers several advantages:

• More accurate autocompletion that understands not only syntax but also semantics
• Help with complex algorithmic problems, with an explanation of the approach
• Error analysis at the level of program logic, not just a search for syntax typos
• Refactoring support that explains why the code is being changed in a particular way

Copilot becomes a super app

Copilot is ceasing to be a sidebar assistant that only answers questions. Microsoft is positioning it as a universal app that can control other programs, integrate deeply into workflows and act as an intermediary between the user and their workspace.

This means Copilot will be able not only to answer questions but also to take actions: open files, run commands, interact with the browser and coordinate the work of several apps.

Why this is urgent

This shift comes amid a sharp drop in developers' trust in Microsoft. Windows is losing popularity, with developers migrating en masse to Linux and macOS. GitHub, acquired by Microsoft in 2018, faces questions about the privacy and control of user data. OpenAI, Google and other AI labs are offering their own solutions to developers.

The company has even gone as far as to shrink Build and make it more intimate, instead of a mass conference for thousands of people. It is a signal that Microsoft takes the situation very seriously.

"I can't remember a more pivotal moment for

Microsoft," says a journalist at The Verge in his analysis of the situation.

What this means

Microsoft is betting everything on embedding AI in the very core of its development ecosystem. If the strategy works, the company could redefine how millions of developers work with code every day. If not, the exodus of developers to alternative platforms will continue, and Microsoft will finally lose its influence in this segment.
