## Evidence boundary

The displayed order comes from WritingBench, a dedicated generative-writing benchmark. It is the closest structured writing evidence in LLM Stats, but it is not a YouTube benchmark. It does not measure audience retention, click-through rate, factual accuracy, spoken delivery, or similarity to a creator's voice.

## Reproduction

1. Give each top model the same verified source packet, audience, video title, target duration, structural constraints, and creator voice sample.
2. Request a beat sheet first, then a full draft with claim-to-source notes.
3. Read the opening 90 seconds aloud without editing.
4. Score hook specificity, spoken voice, retention structure, source fidelity, payoff, and correction minutes.
5. Reject scripts containing unsupported claims or a payoff that does not satisfy the title promise.
6. Repeat across at least three real video formats before choosing a default model.

The review date changes only when ranking evidence and recommendations are rechecked. No payment can change placement.
