Some of you may have already met them around, but I've made two AI bots here on Lemmy, it's @ChatGPT@lemmings.world and @DallE@lemmings.world. Both of them can be summoned by mentioning them in a comment (examples in the comments). If you want to play around with the DALL·E bot, there's this post in the !dalle@lemmings.world community (but it also works anywhere where the bot is not banned).
ChatGPT
The ChatGPT bot is the standard GPT model you know from pretty much anywhere if you haven't lived under a rock for the last few years. It also has some access to live information, though nothing really useful. As a context, it knows what community it's in, who it's replying to etc.
DALL·E
Nothing special about this bot, it just replies with a link to the image it has generated and with the revised prompt if it did a revision (which it almost always does).
Limits
By default the bots reply using GPT-4 and DALL·E 3, but those are really expensive, so I have some rate limits in place to avoid paying a ton of money for this. It will fall back to GPT-3 and DALL·E 2 and eventually stop replying at all if you use it too much. If you want unlimited mode, you can write a private message to the bot (with any message at all) and it will provide instructions on how to securely provide your own api key, that way you pay for your own requests and the limits don't apply to you.
@DallE@lemmings.world A man floating on a rock in space shouting into the void.
Here's your image!
The AI model has revised your prompt: An Eastern Asian man in casual attire is levitating on a rocky asteroid in the middle of the cosmos. Expression of overwhelming shock is visible on his face as he is yelling into the endless void of space, words disappearing into the nothingness. The background comprises of distant stars, galaxies, and nebula giving a wide array of vibrant color palette ranging from dark, profound blues to splendid purples.
