it seems more interested in conversations, the api playground when asked for "names for an ice cream shop" will give you a list of ideas, whereas chatgpt will give you a list, tell you why they're a good idea and will give you more ideas so you can make more ice cream shop names. also the api playground doesn't seem to have a moral compass, if you ask it to make insults for somebody specific
it will happily oblige, whereas ChatGPT will stop you.
