You use GPT-4? Wait till I pull out MBR-5 and take your job 😎

So... I wasn't positive on what MBR-5 was (though i did vaguely remember it) so I quickly googled to confirm. I found this instead...

I'm really curious now if they were aware of the mouse brain tool when they finalised the name.

Im still on 3.5 as 4 is "pay to use"
