DeepSeek-V2.5 leads with 78.3%
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 2 entries, 1 of them models we track. We plot every source in the charts below.
Scores over time
All the scores we have, one dot each, so a model tested at several settings appears more than once.

One lab claim next to the leaderboard
Each score a lab reported for its own model, beside the same model's best score on the leaderboard. Gaps mostly come from different harnesses, effort levels and task subsets. 1 of them match, which usually means one side copied the other. Every benchmark.
| Model | Lab says | Board says | Gap |

| DeepSeek-V2.5 Sep 2024 | 78.3% DS-FIM-Eval (in-house) | 78.3% Leaderboard | Same |
