Description
Microsoft 365 Copilot

Microsoft 365 Copilot is an AI-powered tool that helps with your work tasks.
Users enter a prompt in Copilot and Copilot responds with AI-generated information. The responses are in real-time and can include internet-based content and work content that users have permission to access.
Users get content relevant to their work tasks, and in the context of the Microsoft 365 app they’re using.
Microsoft 365 Copilot:
- Pairs with the Microsoft 365 productivity apps that you use every day, like Word, Excel, PowerPoint, Outlook, Teams, and others.
So, you can use Copilot in Word to help create a document, in Excel to get suggestions for formulas, in Outlook to summarize an email thread, and in Teams to summarize meetings.
- Uses content in Microsoft Graph to personalize the responses with a user’s work emails, chats, and documents. Copilot only shows the data that users have permission to access.
- Coordinates large language models (LLMs). LLMs are a type of artificial intelligence (AI) algorithms. These algorithms use deep learning techniques and data sets to understand, summarize, predict, and generate content.
The LLMs include pretrained models, like Generative Pre-Trained Transformers, like GPT-4, that are designed for these tasks. To learn more about Generative Pre-Trained Transformers (GPT), ask Copilot.
