LABBench2: An Improved Benchmark for AI Systems Performing Biology Research
TLDR
LABBench2 is a benchmark of nearly 1,900 biology tasks measuring real-world AI capabilities, showing increased difficulty over its predecessor.
Reasoning
The paper introduces a well-structured benchmark with clear methodology and empirical evaluation, but lacks detail on task diversity and potential biases. Its strength lies in addressing real-world scientific tasks, though it remains domain-specific.

Innovations
- Introduction of LABBench2, a benchmark with nearly 1,900 tasks for measuring real-world AI capabilities in biology research, evolving from LAB-Bench with more realistic contexts.
- Public release of the task dataset and evaluation harness to facilitate community use.
Methodology
The benchmark comprises nearly 1,900 tasks that continue LAB-Bench's measurement of similar capabilities but in more realistic contexts. Current frontier models are evaluated on LABBench2, and their performance is compared to that on LAB-Bench to quantify the difficulty increase.
Key Results
Frontier models show substantial improvement on both benchmarks, but LABBench2 is significantly harder, with model-specific accuracy drops ranging from -26% to -46% across subtasks, highlighting remaining performance gaps.
