OpenAI Computer-Using Agent (CUA) leads with 94%
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 OpenAI Computer-Using Agent (CUA) 94%
- 2 ChatGPT agent 89%
| # | Model | Score | Setting | Date | Source |
|---|---|---|---|---|---|
| 1 | OpenAI Computer-Using Agent (CUA) | 94% | Jan 2025 | Model card | |
| 2 | ChatGPT agent | 89% | Jul 2025 | Model card |
The best score passed 85% in Jan 2025
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.
2 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.
