Hi Rocky, Thanks for the question. This blog post (https://www.microsoft.com/en-us/microsoft-365/blog/2023/07/18/introducing-bing-chat-enterprise-microsoft-365-copilot-pricing-and-microsoft-sales-copilot/) is a good place to start to understand the differences between Bing Chat and Bing Chat Enterprise. The major difference between the two is that Bing Chat Enterprise has the commitment to commercial data protection. With Bing Chat Enterprise, user and business data are protected and will not leak outside the organization. What goes in—and comes out—remains protected. Chat data is not saved, and Microsoft has no eyes-on access, which means no one can view your data. And, your data is not used to train the models.
