Windows Will Get Its Own AI Models: What Microsoft Is Preparing for Build

At the Build conference in San Francisco, Microsoft will announce three major initiatives: new AI models embedded directly into Windows, a reasoning model from Microsoft's own AI lab, and a reimagined Copilot as a universal 'super-app'. This is a desperate attempt to regain the trust of developers, which the company has lost in recent years.

What Changes in Windows

The company will integrate AI models at the operating system level. This isn't just a new chat bot in the corner of the screen—it's about a fundamental redesign of how Windows interacts with code, text, and visual content. Built-in models will be able to analyze the context of running programs and offer assistance without the need to switch to a separate application. A developer opens their code editor, and AI is already ready to help, seeing the full project context. For developers, this is especially important: tools will be integrated directly into the development environment (IDE). There's no need to open a browser or chat—all assistance is right where you're working.

Reasoning Model: A Thinking Assistant

Microsoft will announce its own reasoning model. This isn't just a language model for text generation, 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 building an optimal algorithm for data processing. They don't just provide an answer—they show the line of reasoning. For developers, this offers several advantages:

• More accurate autocomplete that understands not only syntax but also semantics
• Assistance with solving complex algorithmic problems with explanations of the approach
• Error analysis at the program logic level, not just syntactic typo detection
• Refactoring support with explanations of why exactly this code restructuring is beneficial

Copilot Becomes a Super-App

Copilot stops being a side assistant that only answers questions. Microsoft positions it as a universal application that can manage other programs, deeply integrate into workflows, and act as a mediator between the user and their workspace. This means Copilot will be able to not only answer questions but also take actions: open files, run commands, interact with the browser, and coordinate the work of multiple applications.

Why This Is Urgent

This reorientation is happening against the backdrop of a sharp decline in developer trust in Microsoft. Windows is losing popularity—developers are massively migrating to Linux and macOS. GitHub, acquired by Microsoft in 2018, faces questions about user data privacy and control. OpenAI, Google, and other AI labs are offering their own solutions for developers. The company has even gone so far as to scale down Build and make it more intimate instead of a massive conference with thousands of attendees. This is a signal that Microsoft takes the situation very seriously.

'I don't remember a more pivotal moment for

Microsoft,' says The Verge journalist in their analysis of the situation.

What This Means

Microsoft is betting everything on embedding AI into the very core of its development ecosystem. If this 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 ultimately lose its influence in this segment.
