Artificial Analysis Long Context Reasoning Benchmark Leaderboard
As of 29 Oct 2026 · 588 ranked rows · Original source ↗
Cost per Intelligence Index task uses Artificial Analysis profile values captured 29 Oct 2026, weighted across the Index evaluations. Workbook cost values mentioned in the source notes below are evaluation-specific.
AA Cost Chart Label is the displayed source value; Cost per Task (USD) is numeric. A bound such as <0.1¢ remains in the label while its numeric cell is blank; if both cells are blank, AA showed no plotted cost point for this model. GPT-6.1 Sol effort-variant rows use scores from Artificial Analysis model profiles captured 2026-09-30; insertion ranks are documented in docs/GPT-6.1-SOL-RANK-IMPACT.md. Values refreshed from the Artificial Analysis evaluation page captured 2026-10-29.
