GPT-6.1 Sol leads with 60.4%
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.
- 1 GPT-6.1 Sol 60.4%
- 2 GPT-6.1 Terra 45.3%
- 3 GPT-6 Sol 38.1%
- 4 GPT-6 Luna 21.8%

Labs report it only in system cards
We read the headline results of 522 launch posts from 52 labs, and none of them list this benchmark. Some system cards do, below.
11 system cards report it, from 1 lab
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.
