There are quite a few safety checks you may be hitting when using chatgpt that are there to try and keep context of what it is (so it'll remind you it can't access the outside world). You can often get around them, but for example there's the work showing you can teach it to render svgs as valid markdown then ask for shapes and colours and get the output. If I ask it to render something though, it refuses telling me it's a language model.

I have had a 17 page conversation with it and been able to ask for summarisations of what we've talked about.
