o1 leads with 89.1% among models released by Feb 2025
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 newest model with a score here came out in Feb 2025, and nobody has reported a newer one. Among the 20 highest-ranked models on the capability index, these have no score yet:
- GPT-6 Astra
- Claude Opus 5.5
- GPT-6.1 Terra
- GPT-6.1 Sol
- and 16 more
- 1 o1 89.1%
- 2 OpenAI deep research 84.1%
- 3 o3-mini 82.9%
- 4 o1-preview 81.8%
- 5 o1-mini 69.5%
| # | Model | Score | Setting | Date | Source |
|---|---|---|---|---|---|
| 1 | o1 | 89.1% | Dec 2024 | Model card | |
| 2 | OpenAI deep research | 84.1% | Feb 2025 | Model card | |
| 3 | o3-mini | 82.9% | Jan 2025 | Model card | |
| 4 | o1-preview | 81.8% | Sep 2024 | Model card | |
| 5 | o1-mini | 69.5% | Sep 2024 | Model card |
2 models have held number one since its release in Sep 2024
Lab claims count from the day the card came out, independent runs from the model’s release.
The best score passed 85% in Dec 2024
All the scores we have, one dot each, so a model tested at several settings appears more than once.
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.
5 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.
