What this benchmark tests
A factual-reliability score that rewards correct answers, penalizes hallucinated answers, and leaves abstentions neutral.
How to read the score
The published metric is AA-Omniscience Index. Springprompt reproduces Artificial Analysis's rounded public-table figure and preserves its underlying numeric value for provenance.
A missing source value is not scored as zero: that configuration is omitted from this benchmark page.
Comparability policy
Why this is a system evaluation
A row identifies the model configuration, but the measured subject also includes the evaluator's prompts, harness, tools, budgets, repeats, and grader.
That is why Springprompt does not combine these figures with vendor claims or results from another implementation simply because the benchmark name looks similar.
What can be compared here
Every row on this page comes from the same Artificial Analysis snapshot · 30 July 2026 leaderboard payload and the same omniscience field.
This filtered table contains only the published GPT-5.5 Instant (June 2026) configurations from the complete official comparison. It does not hide other model families from the benchmark page or merge results from a different evaluation track.
