Built on OpenAI's GPT models and enhanced by Microsoft's proprietary Prometheus model, Copilot combines the power of large language models with Bing's real-time search index to deliver cited, up-to-date answers.
Copilot is integrated across Microsoft's ecosystem — Bing search, Edge browser sidebar, Windows operating system, and Microsoft 365 applications (Word, Excel, PowerPoint, Outlook, Teams). With Bing processing billions of searches monthly, Copilot represents one of the largest AI-accessible audiences for brands.
