This research introduces OPERA, a framework where language-model agents control optical experiments using physically interpretable operators and residuals rather than opaque scoring functions. By decoupling decision metrics from physical outcomes, the system significantly reduces false positives in autonomous experimentation while successfully transferring protocols between digital twins and real-world instruments. This approach addresses critical reliability challenges for deploying AI agents in high-stakes scientific environments where interpretability is paramount.
OPERA: Operator-residual feedback for reliable autonomous optical experiments with language-model agents
arXiv:2608.05990v1 Announce Type: new Abstract: Autonomous agents choose actions using scores that may not reflect experimental success. We developed OPERA, an operator-residual framework for optical experiments. It represents experimental actions as optical operators and evaluates their outcomes using physically interpretable residuals. Operators specify executable changes to measurement, control or reconstruction, while residuals report departures from specified physical conditions. The agent uses both to select, combine or generate operators, and physical performance is evaluated independently against a withheld reference. Across three optical tasks, score-only feedback produced score increases without physical improvement in 23.6--39.0\% of decisions, compared with 0.9--1.9\% for operator-residual feedback. Operator-residual feedback increased the probability of reaching and maintaining task targets and reduced experimental budgets. Protocols selected in digital twins were transferred to three optical instruments, and repeated experiments showed a lower projection budget in structured-light reconstruction. Together, operators and residuals guide autonomous decisions using measurable physical evidence.
