Copilot Gets Brains: Microsoft Unveils ‘Work IQ’ & Agent Mode Integration with GPT-5 and Anthropic

At Microsoft’s recent Ignite 2025 developer conference, the spotlight focused on fully empowering the “AI lifecycle”—from foundational models to end-user applications—enabling enterprises to evolve into true “frontier firms.” During the event, Microsoft unveiled a sweeping set of upgrades for Microsoft 365 Copilot, introducing the new “Work IQ” intelligence layer and “Agent Mode,” while confirming integration with OpenAI’s GPT-5, Sora 2, and even Anthropic’s models. The company also announced Microsoft Agent 365, a platform purpose-built for managing AI agents at scale.

To accommodate diverse workplace scenarios, Microsoft is bringing its latest models into Copilot, including GPT-5, the Computer-Using Agent (CUA) capable of operating a computer autonomously, and Sora 2, its next-generation AI video-creation model. Microsoft is also giving users the option to select Anthropic models, breaking free from its previous reliance on OpenAI alone.

The all-new “Work IQ” is regarded as a major cognitive upgrade for Copilot. It can deeply interpret a user’s work context—emails, documents, meetings—and integrate personal work habits and collaboration patterns. With Work IQ, Copilot evolves from a reactive assistant into a proactive one, capable of anticipating next steps and recommending the most suitable agent to complete a task.

On the application side, Microsoft is officially rolling out Copilot Agent Mode across Office apps:

• Excel: Users may choose either Anthropic or OpenAI reasoning models to handle complex computations.
• Word / PowerPoint: Agents assist in producing high-quality documents and presentations (PowerPoint support is currently available through the Frontier early-access program).
• Outlook: Now supports voice commands and single-click quick actions such as “summarize and reply,” with a preview version arriving in early 2026 capable of understanding inbox and calendar content.

Sora 2 will also be incorporated into workplace workflows, allowing users to create marketing or social-media videos directly through the Create feature.

With IDC forecasting that enterprises will deploy more than 1.3 billion AI agents by 2028, management and security have become pressing concerns. In response, Microsoft introduced the new Microsoft Agent 365 platform.

Agent 365 enables enterprises to monitor, manage, and secure all AI agents—whether they are built using Microsoft technologies, open-source frameworks, or third-party platforms. It integrates Defender, Entra, and Purview, offering a registration hub, granular access controls, visual dashboards, and security-detection features, ensuring these agents do not turn into “shadow IT” within the organization.

To help more companies bear the cost of AI transformation, Microsoft also announced Microsoft 365 Copilot Business, a plan tailored for small and midsize enterprises with fewer than 300 employees. Priced at 21 USD per user per month, it will launch this December.

At the same time, Microsoft introduced Foundry IQ and Fabric IQ to help AI agents more accurately interpret enterprise data and business logic, supported by Microsoft Agent Factory, a one-stop service that enables organizations to build their own bespoke AI agents.
