Show HN: llmgame.ai – The Wikipedia Game but with LLMs

https://www.llmgame.ai
24•jmcallister•1d ago
I used to play the Wikipedia Game in high school and had an idea for applying the same mechanic of clicking from concept to concept to LLMs.

Will post another version that runs with an LLM entirely in the browser soon, but for now, please enjoy as long as my credits last...

Warning: the LLM does not always cooperate

Congrats! I posted my solution above which took it in a completely different climatology direction

There is definitely some work for me to do on the prompting to get the right balance of creativity, specificity, etc. out of the smallest LLMs out there. That being said, there's something enjoyable about finding a way to steer the llm out of a slop loop

> LLM does not always cooperate

Getting from Visible Spectrum to Rainbow seemed impossible (tried all actions)

jmcallister•17h ago
Interesting...if you see my comment/path above, I was able to do "Visible spectrum → Rainbow Chromaticity (places)."

Under the hood, the prompts are all something like this "Generate nouns that are broader, more general categories that encompass 'Piano'. Return exactly three distinct Wikipedia-style article titles that are nouns, formatted as a comma-separated list with no extra text. Do not include descriptions or adjectives. Focus on specific, named entities or concrete noun concepts only."

The outputs are then deduped from previous generations and any new options are displayed. Based on my result, if you spammed 'deeper' enough, the model would eventually have given you 'Rainbow Chromaticity'.

Uncooperative and non-deterministic.

Crushed it, any thing you want to see added?

Have been thinking to add an Intersection action which takes the 'mean' of two topics. Daily leaderboard of fastest paths is another one.
