This is a Problem - Quick Response Mode Missing in Copilot

Hi,

I noticed Quick Response mode has completely disappeared from Copilot, and have seen many other users report the same issue starting January 2026 on MS Q&A site.

I also read that Microsoft is pushing a new Smart Mode, which changes how responses work and may be replacing older models.

The Quick Response mode fit my workflow far better than Think Deeper and Smart does. 

Since it disappeared, and the introduction of Smart Mode, I have constantly run into issues because now the app is making it's own decisions and interpretations of subjects and projects which is extremely frustrating because it's 2 steps forward and 2 steps back.

Taking away the ability to choose which mode a user prefers, and leaving it up to the bot, is taking away personal preference and what works for individuals needs.

Quick Response was added during the GPT-5 update in 2025, so I don't understand why it suddenly vanished.

Can someone please explain what's happening and whether QR is coming back, as this mode is something I need due to limited time and needing to finish projects.

Please and thank you.
