This is a fair analysis, thanks for taking the time.

As far as I can tell the Google + Wikipedia solution gets the name of Cambridge University wrong: Wikipedia lists it as "The Chancellor, Masters and Scholars of the University of Cambridge" whereas GPT-5 correctly verified it to be "The Chancellor, Masters, and Scholars of the University of Cambridge" (note that extra comma) as listed on https://www.cam.ac.uk/about-the-university/how-the-universit...

I tried to reverse engineer the system prompt in the cake pop conversation https://chatgpt.com/share/68bc71b4-68f4-8006-b462-cf32f61e7e... purely because I got annoyed at it for answering "haha I believe you" - I particularly disliked the lower case "haha" because I've seen it switch to lower case (even the lower case word "i") in the past and I wanted to know what was causing it to start talking in the same way that Sam Altman tweets.

But that's an Oxford comma! You can't use that when describing Cambridge.
