Microsoft 365 Copilot: Wave 2 AMA

Great question. On Monday we announced that GPT-4o is now used by Microsoft 365 Copilot. We use a large variety of models and model versions across Copilot, matching model capabilities with the precise needs of each feature. You probably saw our comments at the beginning of Monday's event / blog describing the improvements in speed and quality. Beyond that, you refer to Copilot's semantic index. The semantically indexed Microsoft Graph gives Copilot access to information across a user's life at work -- not just files an documents, but meeting transcripts, chats, etc., in addition to the nodes between this data (i.e. which files to prioritize given your own history). This is a unique capability, and from our experience users find increasing value the more they use it, getting more familiar with the data it can access and how to work with it to get the best responses. Our advice is always to start with the recommended prompts in Copilot Lab to get a good foundation, then build from there.
