LifeSciBench
Models complete 750 expert-written life science research tasks, often with attached figures, tables, or sequence files. Graded against expert rubrics as score and pass rate.
750 expert-authored tasks over seven workflows and seven biological domains. 1,062 task artifacts, 173 scientist contributors, 19,020 rubric criteria and 453 expert reviewers. Launched 17 June 2026.
- Level
- Expert Specialists with years of training, often over hours of work
- Scored
- Graded by a model A language model scores each response, usually against a rubric.
- Answers

GPT-6 Astra leads with 60.3% 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 60.3%
- 2 GPT-5.6 Sol 59.9%
- 3 GPT-5.6 Terra 56%
- 4 GPT-5.6 Luna 51.2%
| # | Model | Score | Setting | Date | Source |
|---|---|---|---|---|---|
| 1 | GPT-6 Astra | 60.3% | Sep 2026 | Model card | |
| 2 | GPT-5.6 Sol | 59.9% | Jul 2026 | Model card | |
| 3 | GPT-5.6 Terra | 56% | Jul 2026 | Model card | |
| 4 | GPT-5.6 Luna | 51.2% | 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.
