Microsoft 365 Copilot gets a major design overhaul and speed boost

Microsoft is redesigning Microsoft 365 Copilot in Office apps with a larger prompt box and a simpler, more adaptive interface.

The updated experience launches more than twice as fast and improves complex chat response time by 10%.

Work IQ now helps automatically choose the right AI model for the task, while still letting users pick a model manually.

The refresh signals Microsoft’s focus on making Copilot faster, more integrated, and better at structured output.
