Modelica Agent Workflow Benchmark - Model Generation: 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 50 generation tasks: build a Modelica model from an engineering brief that must also meet a private behavioural contract; percent of tasks passed in one run, higher is better.

Metric: Tasks passed (%; 50 Model Generation tasks: build a Modelica model from an engineering brief that must pass interface, model-check and simulation gates and a private behavioural contract; 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.
