Modelica Agent Workflow Benchmark - Model Repair: leaderboard
The Modelica Agent Workflow Benchmark (2026) scores agent harnesses on physical-system modeling in Modelica with a benchmark-owned evaluator outside the agent loop. This board covers 132 repair tasks: fix a Modelica model with an injected fault so that it passes model checking and simulation; percent of tasks passed in one run, higher is better.
Metric: Tasks passed (%; 132 Model Repair tasks: correct a Modelica model with an injected fault (123 fail model checking, 9 fail simulation) so that the benchmark-owned evaluator's interface, model-check and simulation gates pass; one fresh isolated run per task and harness-backend pair, the agent's explicit submission scored outside the loop; OpenModelica 1.26.1). Source: arxiv.org. Saturation forecast: Around February 2027. 4 models tracked.
