M365 Copilot Chat is a chat interface powered by OpenAI’s GPT4o that serves up responses based on web data (rather than information held in the Microsoft Graph, as per the paid M365 Copilot subscription). It also includes features such as Copilot Pages and image generation, as well as data protection and IT admin controls at no cost to users.

Microsoft’s M365 Copilot Chat is a new consumption-based AI product similar to Security Copilot, while the vendor also has license-based GenAI offerings as well.
