MethodologyHow scoring works

Prompt

The model is told to reply with exactly one 5-letter word per turn, that any extra text is penalized, and that duplicate letters are allowed.

Score

Lower is better. Each puzzle score is the turn the word is solved on, or 10 if the model never solves it within 10 turns. Invalid guesses still count as turns.

Execution

Benchmark runners execute locally, simulate the Wordle judge deterministically, cache results in Neon, and skip recomputation for models that already have stored scores.
