The ChatGPT bot here on Lemmy should now respond much faster than it used to because instead of checking for mentions every 5 minutes, it now receives a notification exactly at the time you mention it.
If you don’t know how to use it, just tag it in a comment (@ChatGPT@lemmings.world) and it will reply to the text in the comment.
You can also interact with DallE, that’s my other bot (well, technically it’s the same bot, just with a different username), see the other reply.
