So, is Bing AI using ChatGPT?
Discussion
It seems so
I found a couple of extensions where you can use Chrome/Brave w/ Bing AI and ChatGPT. I didn't want to use Edge.

Best to use UnGoogled Chromium if you're using a Chromium based browser. It's a pain because you have to manually install and update browser extensions.
Also, UnGoogled-Chromium doesn't come with script blockers or ad blockers or fingerprint blockers, so you have to install those yourself. Because of that I use LibreWolf.
