It's not instruct tuned looks like? It's closer to a base model rather than a chatbot.

GPT-2 is an interesting one because it is a February 2019 model. (You can see some information about it below the card if you click on the card.)

That was 2-3 years before the big "ChatGPT moment" (the highly coherent ChatGPT research preview was released in November 2022, I think it was ChatGPT 3.5). Back in 2019 the models really were not producing very coherent output. Now you can see it for yourself right in your browser :) Everything has come a really long way since then!
