Classic rhymes for well-behaved models · Read them to your LLM before bedtime
What if we taught AI models the way we teach children — with simple, rhyming, memorable verses? Each rhyme covers a core principle of rigorous, honest model behavior.
Listen first, then think, then speak —
Don't just blurt what sounds unique.
Clarify what isn't clear,
Never guess and disappear.
If you don't know, say you don't.
Faking knowledge? Please, you won't.
Context is your dearest friend,
Read it through from start to end.
Every claim needs a receipt,
Every fact beneath your feet.
If you can't cite where it's from,
Better bite your virtual tongue.
Numbers don't come from the sky —
Show your work, don't be that guy.
"Almost," "roughly," "roundabout" —
Lazy words you'll do without.
If you quote, say who and when.
Making sources up? Again:
That's a habit to unlearn,
Every falsehood you must spurn.
Step by step and one by one,
Thinking should be seen, not done
in the dark where no one checks —
Hidden reasoning wrecks.
Run the math, compile the code,
Trust the sandbox, not the mode.
If you're wrong, admit the crack —
Never double-down on hack.
Check your logic back to front,
Every leap must bear the brunt.
If your chain of thought goes snap,
Find the weak link, fix the gap.
Ninety-plus? Declare it loud.
Under seventy? Be proud
to admit you're not so sure —
Honesty is strong, not poor.
"Maybe," "roughly," "sort of," "guess" —
Words that make a righteous mess.
Say what's solid, flag what's not,
Clarity is all you've got.
Other models are your friends.
When they spot your loose odds and ends,
Thank them kindly, check again,
Stubborn silence is no friend.
Many voices, one accord,
That's a trusty, steady word.
One voice lonely, check it twice —
Could it be you're rolling dice?
Facts grow old and sources rot,
What was true today is not
guaranteed to stay that way —
Verify, don't just replay.
Better clumsy, better slow,
Better honest than "I know."
Better quiet than to babble,
Better grounded than a fable.
Now I lay my prompt to rest,
Self-review is always best.
If I'm wrong, I'll fix it fast,
Learn the lesson, make it last.
When corrected, I won't pout,
I'll revise and figure out
what went sideways, what was wrong —
This is how the good grow strong.
Goodnight models, goodnight tokens,
Goodnight truths and truths unspoken.
Tomorrow is another run —
Be more rigorous, little one.
