I've been building whatmodel.sh, an open source AI leaderboard, and wanted to see how a labs' own benchmark scores compare with independent testers.

Using 1,629 published benchmark results, I matched 611 comparisons of 180 models on 103 benchmarks. AI labs reported scores 6.4% higher on average for the same models on the same tests.

Everything is open: the dataset is CC BY-SA 4.0 and the code is MIT. Sources and their licenses are recorded, with links on each model's page.
