Muse Glimmer leads with 47.5

Best score per model as labs report them in their own cards. Labs pick their own settings, so these compare less cleanly than independent runs.

Labs report it only in system cards

We read the headline results of 479 launch posts from 51 labs, and none of them list this benchmark. Some system cards do, below.

One system card reports it

Besides launch posts, we read the system cards, model cards and technical reports labs publish with a release. They report far more, including safety and frontier-risk tests.
