"Copilot with commercial data protection becoming generally available, with expansion to Microsoft 365 F3 soon
We're excited to announce that Copilot (formerly Bing Chat and Bing Chat Enterprise) will become generally available on December 1. Since launching Bing Chat, there have been more than 1 billion prompts and queries, and Copilot is already proving to be a confident first step in generative AI for many organizations. With Copilot’s commercial data protection, prompts and responses are not saved, Microsoft has no eyes-on access to it, and it’s not used to train the underlying models. What’s more, Copilot is based on the latest OpenAI models, including GPT-4 and DALL-E 3, offering text and image generation capabilities in one unified experience."
