DeepSeek-V4-Pro leads with 120.0

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.

The benchmark's own leaderboard has 5 entries, 4 of them models we track. We plot every source in the charts below.

Number one over time

Lab claims count from the day the card came out, independent runs from the model’s release.

Scores over time

All the scores we have, one dot each, so a model tested at several settings appears more than once.
