scBench-Long: Verifiable Benchmarking of Long-Horizon Single-Cell Biology

arXiv:2606.26563v1 Announce Type: cross Abstract: Single-cell studies require analysts to convert raw measurements into specific biological claims through multi-step workflows and integration of metadata, assay context, and auxiliary evidence. Existing AI-biology benchmarks largely measure broad knowledge, executable workflows, or local analysis steps. We introduce scBench-Long, a benchmark for long-horizon single-cell biology in which agents must recover scientific conclusions from raw or near-raw data without prescribed methods. The benchmark contains 21 evaluations spanning melanoma CD8 T-c

Why this matters
Why now

The proliferation of AI in scientific research necessitates more robust and verifiable benchmarks to assess agent capabilities in complex, multi-step biological analysis.

Why it’s important

This benchmark helps advance AI agents from narrow task execution to more holistic, scientific discovery, potentially accelerating breakthroughs in biological understanding and drug development.

What changes

The introduction of scBench-Long enables the rigorous testing and validation of AI agents designed to perform long-horizon single-cell biology, moving beyond isolated steps to full scientific workflows.

Second-order effects
Direct

AI agents will be developed to better emulate human scientific reasoning in biology.

Second

Faster, more accurate identification of disease mechanisms and therapeutic targets will emerge.

Third

The role of human scientists may shift more towards experimental design and high-level interpretation, with AI handling much of the data interpretation.
