I have been cross checking it with stored chatgpt4 answers and the wording is different but the answers seem comparable. It fails in my favorite one: There are 3 events, A, B and C. Event C is always before B. Given this, enumerate all possible permutations of the events. Also the weirdest thing is happening: chatgpt4 reports that they are busy and does not let me login (I pay for plus). Is everyone cross checking? EDIT: chatgpt4 started working again. It actually answers the event order question correctly, while bard fails on it. EDIT2: "how do I install a PC in my RAM?" The both agree, but ChatGPT4 is the one that gives the perfect (and long response). Bard tells that the RAM loses memory when turned off and as a conclusion, I cannot install a PC.
