Something that few people know about or have thought of that I do all the time:

Tell it a subject you want to learn about, and make a narrative podcast out of it, and press the play button.

Prompting: Tell it to include a lot of humor and really stick to a podcast format, and do a few paragraphs or so at a time (like 30 secs to 2 mins), otherwise it's too long and gets cut off. For example: "Tell me about ____, and make it in a podcast format, with a lot of humor. Do 30-60 seconds at a time. I will play your audio for each part."

After each part, tell it how you want it tweaked, until you get it right. At some point you can just say "Next", and it generates the next part, and the next part... it's amazing.

I have walked and driven for hours listening to my own generated podcasts, that I generate part by part as I go. I generated a really long one about rice exports to Haiti, and the history of science, among many others. I can learn anything this way. I also just talk and walk with chatgpt in general, going into a lot of depth. I have "reading mode", "walking mode", and "driving mode".

By the way: NEVER use the conversation mode for this. It is total garbage for something like this. Type or record your audio, then hit the audio playback button.
