Comparing models without benchmarks

Every model comparison is an editorial judgement wearing statistics. The honest comparison says who judged, how, and why the score is a judgement — not a benchmark.

Key takeaways
  • A fidelity score is a judgement from recorded runs, not a benchmark — say it next to the score.
  • Per-model tabs with the same brief keep the comparison honest about what is equal.
  • The verdict callout is editorial by nature; label it as such instead of pretending to be a machine.

The honesty line is part of the scoreboard

This site's prompts print fidelity scores with a standing honesty line: scores are editorial judgements from recorded runs, not benchmarks. The line is not a disclaimer — it is the unit of the number. A score without its unit is a number pretending to be a fact; a score labelled as a judgement is a number you can act on.

Equal briefs, labelled verdicts

The honest comparison runs the same brief through each model and shows the answers side by side in tabs, with per-tab notes. The verdict — which one wins — is an editorial call and should wear the label 'editorial pick', as this site's compare demo does. A machine-flavoured verdict that was written by hand is a benchmark in a costume.
