My brother asked ChatGPT about our grandfather, who was a minor historical figure in Saskatchewan.He got a convincing answer but it gave him a new middle name, changed his birthplace, and was 6 years off on his death. Close but no cigar.
I asked the same question, this time got no middle name and his dates were moved 68 years into the future (relative to the actual ones).
I asked 'are you sure?' and it apologized, but 'As an AI language model, I do not have access to real-time information, and my knowledge is based on data available up until September 2021.' My grandfather died in 1937.
I asked the original question again and got 'never heard of him' (paraphrasing a long-winded answer).
I know, I know, GPT 4 will be much better
