Microsoft announces Copilot Tuning at Build 2025: What it means for everyday users

Microsoft Build

At its Build 2025 developer conference, Microsoft introduced a powerful new feature called Copilot Tuning. While it’s designed for businesses, the technology behind it is something regular users might want to understand too because it hints at the future of how we’ll interact with AI in our everyday work.

Copilot Tuning lets businesses train Microsoft's AI tools, known as Copilot, to do specific tasks using their own data, workflows, and preferences. And the best part is, you don’t need to be a programmer to do this. It’s a no-code experience made possible through Microsoft’s Copilot Studio.

For instance, if you are running a law firm. You could train a Copilot to write legal documents in your firm's specific language and structure. Or if you’re part of a marketing team, you could teach your AI assistant to generate campaign ideas that reflect your brand voice or the needs of a particular industry. This means that instead of a one-size-fits-all AI, businesses can have Copilots that are tailored to their exact needs.

Microsoft says that all of this tuning happens within the Microsoft 365 service environment. In simple terms, your data stays within your company’s secure Microsoft space, and Microsoft will not use it to train its own large language models. That’s a big plus for organizations concerned about privacy and control.

But that’s not all. Microsoft is also introducing a feature called multi-agent orchestration. This allows multiple AI agents to work together on complex tasks. For example, an HR agent, an IT agent, and a marketing agent can all collaborate to onboard a new employee. This kind of teamwork between AI agents could make processes smoother and more efficient.

Another important update is that companies will now be able to bring their own AI models into Copilot Studio. That means even more flexibility and control for businesses that are already working with specific AI technologies.

Copilot Tuning will be available from June as part of Microsoft’s Early Adopter Program. Along with this, Microsoft is rolling out new features like Copilot Notebooks, an improved Create experience, and two new reasoning agents called Researcher and Analyst. These agents are designed to help with more advanced work tasks and will be available through a new Agent Store.
