GPT-5.5 Instant or GPT-5.6 Sol

I am using the Plus plan.

There is one thing I do not understand about the current Chat interface (not Work). In the Intelligence selector, if I select GPT-5.5 Instant and then also select GPT-5.6 Sol, both appear with a check mark. In that case, which model is actually used for my conversation? Am I chatting with GPT-5.5 Instant or GPT-5.6 Sol?

Could you please clarify how this works?

Welcome to the community @jayjman!

You mean like this:

If you choose intelligence instant then you’re using instant 5.5, even though you have selected GPT-5.6 Sol.

Thank you, Larisa!
I forgot to mention my issue is related when I use in browser.
It is easy to understand on mobile that “How to select the Model”.
But confusing in the browser.

I understand. But the same applies even on browser.:slightly_smiling_face:
