The challenge
Hit the exact spec
The model has to return strict JSON in a fixed shape, and right now it does not. This is the actual console you get. Shape the prompt until every field validates, in as few tries as you can.
What we score
It rates your prompting, not the model
Everyone gets the same model and the same spec. The score is your craft: did the output match exactly, did you constrain it well, and how few attempts it took.
Match the spec
The output has to validate against the exact shape asked for. Close is a miss.
Constrain it
We reward prompts that pin down format, tone, and edge cases so the model cannot wander off.
Fewer tries
Landing it in two attempts beats brute-forcing it in twenty. Precision over trial and error.
The leaderboard
