The new architecture combines four major components: Autopilot, Code, Home and Office integration, alongside proactive features in Microsoft 365 and Teams.
What’s new
Autopilot is a persistent enterprise agent designed for long-running tasks. Unlike the previous request-response Copilot model, it can continue working in the cloud after the user leaves.
Each agent can have its own:
- identity and permissions;
- persistent memory;
- cloud computer and workspace;
- access to enterprise context;
- governance and audit controls.
Code lets employees build internal apps using natural-language prompts. Generated applications run in a sandbox and can be hosted inside the company's Microsoft 365 tenant through Copilot Managed Runtime.
The underlying coding stack uses GitHub Copilot technology.
Previous Copilot vs new Copilot
| Previous | New | |
| Core model | Prompt → response | Persistent agents + execution |
| Coding | Assistance | Generate and host apps |
| Office | Copilot inside Office | Office also embedded in Copilot |
| Long tasks | Cowork | Cowork + Autopilot |
| Context | Microsoft 365 | Microsoft IQ + Fabric IQ + Dynamics 365 |
| Proactive work | Limited | Today |
Microsoft says Fabric IQ can provide access to more than 20 million Power BI semantic models, extending Copilot beyond documents and messages into structured enterprise data.
Office moves directly into Copilot
Word, Excel and PowerPoint are now embedded in Copilot. Users can ask Copilot to create a document, spreadsheet or presentation and receive an actual editable Office file rather than transferring generated content manually.
Home also combines Chat and Cowork into one interface. Microsoft plans to automatically route requests between Chat, Cowork and Code depending on the task.
Autopilot is a persistent, proactive and personal agent that keeps working even when you’re not. — Microsoft
Copilot becomes proactive
A new Today experience analyzes information across email, calendars, Teams, meetings and tasks and surfaces important items without requiring a prompt.
Teams is also getting Copilot, allowing Copilot to use the shared context of a channel, group chat or meeting.
The architectural shift is significant: previous Copilot versions primarily added AI to existing Microsoft applications. The new version adds persistent agents, cloud execution, app generation, automatic task routing and proactive workflows. Copilot is moving from “ask AI” toward “give AI a task and let it execute.”
