How we rank
Marketing copy keeps a separate use-case layer from general writing. The matrix slot handles campaign-specific picks; the ranked table remains the Arena-then-MMLU fallback.
- Eligibility — General chat models excluding code/embedding SKUs.
- Editorial slot — The page reserves a six-row matrix for ad copy, SEO long-form, brand voice, free, localization, and overall picks before the ranked table.
- Primary ranking — Chatbot Arena, then MMLU, then newer release.
- Variant collapse — We keep one row per model family (`familySlug` + parameter tier). When headline scores tie within ±0.5 pt (±10 Elo on Chatbot Arena), we pick the canonical SKU by lowest tracked input price, then GA over preview or limited access, then newest `release`. A folded sibling within the benchmark noise band can show a "Tied within margin" chip on that score cell.
- Brand caveat — Benchmarks do not measure CTA compliance, offer clarity, localization nuance, or voice-guide fit; keep human review in the loop.
- Writing boundary — Use `/best/writing` for essays, drafts, and general prose; this page is for conversion and content-marketing workflows.
