Exotic fact recall

Our Benchmarks

Closed-book lookups from five public registries: proteins, ISBNs, museum objects, asteroids and network ports.

Run Sep 8–9, 2026, 85 items.

Method

Each question asks for one exact field from a public registry: a UniProt protein entry, the title behind an ISBN, the accession number of a painting at the Met, the number of a named asteroid, or the TCP port that IANA assigns to a service. Every key is exact, so no judge is involved.

Each registry contributes well-known entries and a random sample from its long tail. The score counts the 85 questions that every model in the original panel answered, 49 of them from the tail. Reasoning effort was set to high.
