lonely 20 questions, a game for people with no friends

Developer foxmoss built a 20 Questions web game powered by a machine-learning model called jev that generates probabilities rather than text and uses no LLMs, according to the project's page. For each round jev picks 10 random nouns from Wonder Words, selects the easiest to guess, and evaluates each yes-or-no question to determine whether the player has identified the word. The project is offered through Hack Club AI for teenagers and is described as costing nearly nothing to run.

you may be sad and have no friends but you can still play 20 questions.

powered by machine learning, yes, yet uses no LLMs & costs nearly nothing to run.

1 common english noun, 20 questions, ask yes or no questions.

...

so how does this work?

jev isn't an llm. it doesn't generate text. all it does is generate probabilities of choices i give it.

so in context, for every user 10 random nouns are picked from wonder words, jev decides whats the easiest to guess and uses that word.

every time you ask a question jev evaluates if question is yes or no, and if the question means you know what the word is.

we send those results back to the user, and that's the game.

if you want to try out jev yourself & you're a teenager check out hackclub ai !
