People need to understand that ChatGPT isnt real AI. it isnt thinking and it isnt learning and adapting. its a language model that has been trained on the data that was available at some point plus some live data search.
DTV is a good example here. There is very little sources about it. And many sources are old, outdated, speculation. Even the „law company“ websites that allways claim to have the correct visa information. While they often produce incorrect information on their sites… „AI“ just takes these infos and trusts those incorrect sources. because there isnt many sources and official sources lack important content as well. most DTV related things are embassy specific in the application process. so its hard to find correct and generalized answers to your questions. its not the „AI“s fault.
On the other hand it is very good when you ask about topics that have plenty sources, official sources, long time established things. it will then find much better answers for you that are usualy fairly correct.
my tip: always let GPT and others link you the sources and then check if they are reliable. only problem is that even law companies put out incorrect things about the dtv which makes it pretty hard to know whats right and whats wrong..
