Into the Unknown (almost) - Completeness: leaderboard
AI agents extend 15 published scientific studies and write follow-up papers. This score is the percentage of papers passing at least 90% of the checks for completing the requested research.
Metric: Papers passing Completeness (%), requiring at least 90% of counted nodes in each applicable gate; 15 scientist-proposed open research follow-ups; GPT-6 Astra max via Codex SDK, full workspace, separated rubrics; per-node majority of four judgments (3/4 required); source agent SDK/CLI and effort retained; higher is better. Explicit zero results are retained.. Source: prometheus-eval.github.io. Source: raw.githubusercontent.com. Saturation forecast: Around November 2027. 9 models tracked.
