They claim it is "thinking", while this is just a hidden text generation part. There is not thinking. There is no understanding. It is just iterating over the same text you fed it over and over again until it extended it to a sufficient degree. One text snippet at a time. The variations in output are a result of the randomized text snippet selection at each iteration. Sometimes it "thinks" you want it's CV. Sometimes it "thinks" you want some weather data or other crap. In fact it isn't thinking at all. It is just generating text.
