A note on these numbers

All scores are as published. Where benchmarks have multiple slices (LiveCodeBench date cutoffs, SWE-bench harness variants), the cell uses the slice the vendor or paper headline-reported.

Closed-model numbers are vendor-reported. They have not been independently reproduced by this list. Treat them as primary-source claims, not measurements.
