Key Capabilities and Use Cases

The integration enables a range of advanced tasks, allowing users to finish real work faster. Identified capabilities include:

Building spreadsheets and presentations
Writing and reviewing code
Understanding long documents
Using tools and working with images
Market research and strategic planning

It's Becoming a True Strategic Analyst, Not Just a Chatbot

The true power of GPT-5.2 in the Microsoft ecosystem comes from its deep integration with your personal work data. Within Microsoft 365 Copilot, the model connects to "Work IQ" to unlock insights, market research, and strategic planning by reasoning across your individual work graph of "meetings, emails, docs, and more."

This transforms Copilot from a generic chatbot into a personalized, context-aware strategic analyst. Instead of asking general questions, you can now ask it to perform highly specific, strategic tasks based on your own work. The kinds of prompts this enables are a world away from simple summarization:

"Based on prior interactions with [person], give me 5 things that will be top of mind for our next meeting.”
Give me the top 3 strategic insights from today’s meeting, and show how they connect to our objectives and key results and upcoming milestones.”
