Code Review
This pull request addresses a bug in the prefix-repetition benchmark script where the return value of _generate_exact_length_tokens was not being handled correctly. The function returns both tokens and a mismatch count, but the original code failed to unpack this tuple for prefix tokens, leading to incorrect behavior. This change correctly unpacks the tuple for both prefix and suffix tokens and accumulates the mismatch counts. The fix also corrects a typo in a variable name (token_mistmatch to suffix_mismatch), improving code clarity. The changes are correct and effectively resolve the bug.
