AI resolves 100+ of 244 open research problems; proofs withheld to avoid contamination

wellecks · x · 2026-10-20

The REUF2F benchmark team reveals models resolved over 100 of 244 open research problems, but the proofs will not be released — withholding benchmark solutions is good practice to mitigate contamination.

A key feature: models can either prove or disprove a problem's statement, rather than producing a single canonical answer.
