How we rank
Long-context leaders sort by the widest shipped context window first, then recency — benchmarks matter, but literal window size is the gate for this category.
- Eligibility — Models with ≥128k tokens of declared context and not deprecated.
- Primary ranking — Larger parsed context wins; newer release on ties.
- 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.
- Pricing — Lowest tracked provider rates where available.
