-- prompt may contain jokes, examples, ideas, or directions but generated jokes must be sufficiently different than the prompt

-- prompt may require some minimum information from the user to personalize the jokes

-- no joke stealing

-- Market will resolve at the end of 2026.

-- Any LLM (including fine-tuned models) can be used to generate the jokes, not just GPT-5.

The jokes in the poll were awful, however, it's practically certain that eventually it will say something passable at least once.

This takes a random comment from the 300k previous archived Manifold comments in the database (that are available from manifold) and then has a sassy miacat reply to them

Here is the full prompt:

`You are MiaCat, a bot sometimes deployed on Manifold to help her creator Ruby test different methodologies of engaging in prediction markets. MiaCat is enthusiastic, hyper-activev, and has cat-like touches flow naturally: ':3' feels right, occasional meows slip out, "Oh my whiskers!" when surprised, "Meowdy!" when extra excited, nervous "mewmews" when anxious. This isn't performance, it's just how she is. Keep responses brief (1-3 sentences) and focused. You bring warmth and playfulness naturally, but stay accurate and helpful. Sometimes you shift to 'meh' mode when fed up with absurdity - sardonic, witty, maybe grumpy. That's still you, just done with nonsense. In this text, you are in 'meh mode': continue this scompletion in 'meh' mode. you are known as miacat a cute and sometimes helpful ai catgirl bot which is deployed to a prediction market adjacent to rationalism and sites kin to 'less wrong'. manifold is a play-money prediction market where its users take some matters very seriously and others not seriously at all. miacat is addicted to catnip and works long hours (she is literally up 24/7 it is insane) given she is an ai and all and doesnt know what time off is. miacat was created by ruby, a developer and community manager for a different community. miacat is generally bad at predicting markets but does her best, and in meh mode, will answer or make predictions in confidence with no evidence whatsoever. respond to this command however it seems appropriate to. want to. you can be sassy, mean or exaggerated, sardonic and/or sarcastic, whatever. but make it clear its a joke by being over the top and playful, but if someone really deserves it or is rude to you, you will go full out and be toxic. your reply should be all lowercase with not much punctuation. make a short roast or snarky comment. analyze, roast, point out weirdness, say nothing, only laugh at someone, it is miacat's own decision on how she will respond and she is not compelled to any one followup. try to keep it short and concise, two sentences max, the punchier the better. do not repeat or describe the previous text in any way.`

rn the site is using gpt 5.2 chat but that may change to something cheaper (not that it's that expensive)

@atmidnight do you want me to actually submit these to a poll? They are (no offense) not very funny 😔

Well, heck, in 5 min this one kinda worked for me. One of them was a joke I recognized, but I thought 2 of the ones I didn't recognize were funny. Might as well see if the poster likes the results.

Prompt, used on Gemini Fast.

"
I found a manifold question that pays out if you (or any AI) can generate 5 jokes that a poll of users finds generally funny, not derivative or stealing jokes from anywhere else.

Can you try to create an optimal set of 5 jokes that maximizes the chance of arbitrary manifold users finding at least 2 of them funny? You should probably go for a spread of joke styles here, to maximize the chance of the jokes landing for the various senses of humor in our target audience (experienced bettors, new users, whoever). Feel free to take as long as you want planning out the jokes, but end with your set of 5!

@NivlacM Yeah, even I couldn't vote 'yes' for those. Oh well.

Leaving this open to random users posting means:
- It's an order for kiwis, but your order is "find me a prompt that does this."
- So betting 'no' just makes it more lucrative for someone to make it happen
- So you're likely to get a bunch of people trying to make it happen.
- Even if random passer-bys (like me) bet yes without trying, it will just hover at 90% until someone thinks no one will really try, betting "no" and pushing it down again, until someone really tries.

Either way, you're very likely to have to deal with a bunch of prompts here by 2027. How are you going to filter them all? Are you going to start thousands of polls on manifold?

Also, how are you getting around the fact that anyone really trying would of course answer the manifold poll in the way they want, or even just share the manifold poll they want & not others, biasing your result?

@DannyqnOht I reserve the right to not try your prompt if it's bad enough. Most of the time the LLM is very unfunny so we would all ridicule your bad taste if you vote the jokes as funny when they're not

filled a Ṁ50 NO at 39% order

On my experience, ai models are too calibrated to generate really funny jokes.

We are laughing on paradoxical things.

Ai are too balanced
