AI Research Evaluation
Authors propose evaluating AI researchers based on a trail of research decisions. On August 18, nine authors posted a framework for assessing scientific AI agents on ChemRxiv, a preprint repository. The framework's unit is the "discovery episode": a preserved sequence of hypotheses, actions, data, and revisions.
The authors suggest evaluating the entire sequence, including episodes of discovery, which record what was known before the next step, the action chosen by the agent, what was observed, and how the plan changed afterwards. For each step, the episode records the code version, instrument settings, human involvement, and safety rules.
The framework breaks down research work into three connected parts: hypothesis, execution, and interpretation. The authors advise starting with limited tasks, which have a clear goal, can be automatically evaluated, and fit within acceptable time and cost. The separate stages can then be connected into episodes and tested through independent repetition, allowing the evaluator to trace the path from decision to data and the next question, as published in ChemRxiv.

Measuring AI Scientists: From Exams to Discovery | ChemRxiv
Large language models and agentic systems are increasingly embedded across the scientific
work-flow, from literature synthesis and hypothesis generation to code execution,
data analysis and writing. This broadening of use exposes a mismatch in evaluation:…
