GeneBench Pro
Agents analyze messy simulated genomics and biology datasets to estimate a decision-relevant quantity across 129 problems. Scored automatically against known answers.
129 problems in 10 domains and 21 sub-domains. Synthetic noisy datasets graded against ground truth. OpenAI calls it a harder expansion of GeneBench. Self-reported scores only so far.
- Level
- Expert Specialists with years of training, often over hours of work
- Scored
- Checked automatically A program checks the result against an answer key, unit tests or the expected final state.
- Answers
- Agent task Many steps in a terminal, browser, desktop, app, game or robot.
GPT-6 Astra leads with 37.1% among models released by Sep 2026
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 Sep 2026, and nobody has reported a newer one. Among the 20 highest-ranked models on the capability index, these have no score yet:
- Claude Opus 5.5
- GPT-6.1 Terra
- GPT-6.1 Sol
- Claude Sonnet 5.5
- and 13 more
- 1 GPT-6 Astra 37.1%
- 2 GPT-5.6 Sol 28.7%
- 3 GPT-5.6 Terra 23.3%
- 4 GPT-5.6 Luna 10.8%
| # | Model | Score | Setting | Date | Source |
|---|---|---|---|---|---|
| 1 | GPT-6 Astra | 37.1% | Sep 2026 | Model card | |
| 2 | GPT-5.6 Sol | 28.7% | Jul 2026 | Model card | |
| 3 | GPT-5.6 Terra | 23.3% | Jul 2026 | Model card | |
| 4 | GPT-5.6 Luna | 10.8% | Jul 2026 | Model card |
2 models have held number one since its release in Jun 2026
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.
One lab put it in a launch post in the last six months
Launch posts from every lab that has listed it, one tick per post. Tall colored ticks include it, and short gray ones leave it out.
| Date | Launch post | Score | As the post writes it |
