Details
Microsoft has added a mode selector to Copilot chat, allowing you to choose how much reasoning to apply to your prompt.
Choose from:
- Auto (default): Copilot decides how long to think
- Quick response (chat): Copilot answers right away
- Think deeper (reasoning): Copilot thinks longer for better answers
Your choice is remembered and retained for new chats.
Availability
Rolled out in early December 2025.
