AA-Omniscience benchmark: 6,000 fact questions show top models still err ~25% without search

randal_olson · x · 2026-09-30

Randall Olson shared Artificial Analysis' AA-Omniscience data: 6,000 questions about specific facts across 42 work topics, answered without search. Wrong answers are measured as a share of answers given (declined questions excluded).

Headline finding: even the best models get roughly 1 in 4 answers wrong without search — if a fact matters, have the model look it up.

He also released evident-charts, an open source agent skill for Claude Code, Codex, Cursor and more that teaches AI coding agents to make clear, honest charts: it checks data first (totals mixed with parts, duplicate rows, placeholder codes, preliminary months) and critiques and rebuilds bad drafts — e.g., raw counts on a log scale, the EU total ranked among its own members, meaningless rainbow palettes.
