_?

I entered a little more than an underscore, so it's somewhat of a falsehood.

“pi 97”

The value of pi (π) to 97 decimal places is: 3.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679

This is pi to 100 decimal places, not 97.

Query: eerie sorted
GPT-4: Sorting the word "eerie" alphabetically results in "eeeri".

This one's quite inconsistent. The longer "Sort letters eerie", though, elicited a wrong answer 10/10 times, always with an extra r and sometimes an extra e, though the letters' ordering was correct.

ChatGPT sucks at code golf.

[User] am i dead

[GPT-3.5] I'm just a computer program, so I can't determine your current state of being. If you're feeling uncertain or concerned about your health, I would strongly recommend seeking immediate medical attention or contacting a healthcare professional. They can provide you with the necessary assistance and guidance to address any health-related concerns.

One could argue this is clearly false, since if I am interacting with the model then I must be alive. (However, that is up for debate.)
