Microsoft is rebranding Bing Chat and is now simply calling it "Copilot," giving its generative AI assistant a consistent identity across its products. Similarly, Bing Chat Enterprise will be known "Copilot Pro," and it will be generally available starting on December 1. It will still be free for specific Microsoft 365 licenses, which will include F3 accounts for frontline workers, though the $5-a-month standalone subscription will be available that day, as well. The Copilot Pro is based on OpenAI's latest models, GPT-4 and DALL-E 3, and the company says it will not save prompts and responses. Microsoft will not see interactions happening within Copilot Pro at all, and it will not use customers' chats to further train the underlying models.
