Tampermonkey script for Microsoft 365 Copilot Enterprise/Education
Stops the “auto” default and lets you pick your preferred GPT model in one click.

What it does

Tired of:

Clicking Auto, then More, then selecting one of four GPT versions? (2026/03/10)
Being forced to use the default model every time you start a new chat?
Not being on Windows (no desktop app) and stuck with the web UI?

This script fixes that by automatically selecting the model you want when Copilot loads.

Note: Only works with the enterprise/educational edition of M365 Copilot, not the regular Copilot.

Install steps

Install the Tampermonkey extension for your browser.
Open the extension and choose Create a new script.
Copy & paste the contents of Auto Select Copilot - GPT Mode-1.1.0.user.js (or import the file directly).
Refresh the M365 Copilot page – it should now switch to your preferred model automatically. (For chrome, you may need to enable tampermonkey first through extensions page etc, then change 'button' to 'option' [I think microsoft sometimes does this to prevent these kinds of extensions])

Customization

The default target model is GPT‑5.4 Think Deeper, chosen for its high benchmark scores and robust prompt handling.
To change the target model, edit the script and adjust the targetMode or run the “Set target mode” action from the menu.
If you don’t want the script to open the More menu (i.e. you just want “Ambiguous / Quick response / Think deeper”), turn off the clickMore option—then it won’t expand the menu at all.

Enjoy a smoother Copilot experience with 3 less clicks!
