@RealGene @larsmb likely it just means it makes something up, as there are unlikely to be data for all numbers / words and they are also very similar. Sometimes it will actually use python code in the background which gets the right answer. (Which in other cases has hilarious results; if you as ChatGPT (free version) to draw a sketch of sth, it will create python code to draw various lines and circles and show you the output, which in no way resemble anything.)
