DSBio: Scientific Analysis Tasks

DSBio is a suite of 90 expert-derived bioinformatics tasks constructed from peer-reviewed academic publications and public scientific datasets.

These tasks are designed to evaluate whether agents can perform domain-grounded scientific analysis, including:

  • Interpreting high-dimensional biological data (e.g., single-cell and spatial omics)
  • Understanding domain-specific terminology and conventions
  • Executing multi-step analytical workflows with specialized libraries
