Lumina Score vs Cost per Task

USD per task; time is mean generation time per task for GPQA/airline, mean search-task latency for search lanes. These definitions are not interchangeable. Positive published telemetry only; missing/zero telemetry is not represented as free or instantaneous.

Method & coverage

Runs pair a model with a web search engine through the OpenRouter server-tool or plugin surface. A run contributes only when it succeeded, is visible on openrouter.ai, has no epoch marker, ran through a public search surface, answered at least 45 questions, and is the latest run of its resume lineage; within a lane only runs sharing the most recent configuration are pooled. Score is pooled correct answers over pooled questions, which is the value the suite pages plot.

How the Lumina conversion works

1,000 + 75 × ((original score − 68.41717138767086) / 1.8264290679540451). The result is rounded once. Scores may tie.

Frozen initial observed text-only cohort; one mean per exact publisher release/API, balancing repeated settings/routes within that release. Original score and protocol remain separate. No inferred variants or future refitting.

Identity, exclusions & attribution

Runs pair a model with a web search engine through the OpenRouter server-tool or plugin surface. A run contributes only when it succeeded, is visible on openrouter.ai, has no epoch marker, ran through a public search surface, answered at least 45 questions, and is the latest run of its resume lineage; within a lane only runs sharing the most recent configuration are pooled. Score is pooled correct answers over pooled questions, which is the value the suite pages plot.

Routing and search-lane observations are distinct configurations, not independent model releases. No effort is inferred from an unlabelled default or a turn budget.

Source standard deviation is retained in original evidence only, not presented as an inferred confidence interval.

Text questions and text function/search tools. HLE uses the explicitly documented text-only subset; multimodal questions excluded.

Standalone text benchmark; no new combined index. Source identity/effort/protocol qualifications remain in Data and CSV.

All published reasoning settings, including Claude Max, are included by default. Display labels use Low and xHigh; source labels remain in the retained records.
