SciΠvot: Benchmarking Principal-Investigator Judgment at Pivotal Moments of Scientific AutoResearch Agents Researchers introduced SciΠvot, a benchmark for evaluating principal-investigator judgment at pivotal moments in scientific auto-research agents, addressing the difficulty of assessing open-ended research decisions that depend on project context. The benchmark targets LLM agents that can run scientific experiments for months with little human supervision but still require scientific judgment for reliable autonomous research. Large language model LLM agents can keep scientific experiments running for months with little human supervision, but reliable autonomous research also requires scientific judgment. Evaluating scientific judgment is difficult because research decisions are open-ended and depend on project context.
