Evidence key: Observed
Rows are ordered by the value HLE-Verified: A Systematic Verification and Structured Revision of Humanity's Last Exam published, highest first. The source does not state whether a higher value is the better result, so this page does not either: for a benchmark that measures a rate of failure, read the table from the bottom.
