I see a huge progress made since the first gpt-4 release. The reliability of answers has improved an order of magnitude. Two years ago, more than half of my questions resulted in incorrect or partially correct answers (most of my queries are about complicated software algorithms or phd level research brainstorming). A simple “are you sure” prompt would force the model to admit it was wrong most of the time. Now with o1 this almost never happens and the model seems to be smarter or at least more capable than me - in general. GPT-4 was a bright high school student. o1 is a postdoc.
