ThermoQA - Cycle Analysis: leaderboard
Metric: Tier 3 weighted step score (%): 82 full cycle analyses across ten cycle types (Rankine, Brayton, vapor-compression refrigeration, combined cycle), 15 to 60 weighted steps each, over the 293 open-ended engineering thermodynamics problems of ThermoQA (ground truth computed with CoolProp 7.2.0 for water, R-134a and variable-cp air), zero-shot with a symbol = value unit answer format, each model at its stated reasoning setting, mean of three independent runs; values are extracted by regex and gpt-4.1-mini and a property counts as correct within 2 percent relative or 0.5 absolute tolerance (0.03 for quality, 0.02 for efficiencies and COP); higher is better. Source: arxiv.org. Saturation forecast: Around January 2027. 6 models tracked.
