In the authors’ words
Language models rapidly become more capable in many domains, including biology. Both AI developers and policy makers [1] [2] [3] are in need of benchmarks that evaluate their proficiency in conducting biological research. However, there are only a handful of such benchmarks[4, 5], and all of them have their limitations. This paper introduces the Biological Lab Protocol benchmark (BioLP-bench) that evaluates the ability of language models to find and correct mistakes in a diverse set of laboratory protocols commonly used in biological research. To evaluate understanding of the protocols by AI models, we introduced in these protocols numerous mistakes that would still allow them to function correctly. After that we introduced in each protocol a single mistake that would cause it to fail. We then presented these modified protocols to an LLM, prompting it to identify the mistake that would cause it to fail, and measured the accuracy of a model in identifying such mistakes across many test cases. Only OpenAI o1-preview scored similarly to the performance of human experts, while other language models demonstrated substantially worse performance, and in most cases couldn’t correctly identify the mistake.

OpenAI deep research leads with 49% among models released by November 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 November 2025, and nobody has reported a newer one. Among the 20 highest-ranked models on the capability index, these have no score yet:
- Claude Fable 5.2
-
Gemini 4 Carbon
- GPT-6 Astra
- Claude Opus 5.5
- and 16 more
- 1 OpenAI deep research 49%
- 2 Grok 4 47%
- 3 o3-mini 41%
- 4 Grok 4 Fast 39%

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.
9 system cards report it, from 3 labs
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.
