AI: a new hobby

Firefox has decided to install ChatGPT on my system. At some point I will have to find out how inquisitive it is, but for now I've been setting it puzzles.
So far I have set it the following puzzles:
1) The Goldbach Conjecture - PROVED (for low n).
2) 5-disc Hanoi - PASSED.
3) Write a valid C90 program that is invalid C99 - FAILED.
4) Today's bucket-slosher from Kevin's BB site - PASSED.
5) Yesterday's BB multiple choice - FAILED (after six attempts!).
