Key Findings
1. Supercritical is the discriminator
All models struggle above the critical point (T > 373.95°C, P > 22.064 MPa). The best score is GPT-5.4 at 86.7%. Why? LLMs memorize steam table values from textbooks (Çengel & Boles, Moran & Shapiro) but don't know the IAPWS-IF97 equations of state. Near the critical point, properties change extremely nonlinearly — linear interpolation from memorized table entries produces large errors.
Example: At 402°C and 25.3 MPa, Claude Opus interpolated from memorized values and reported h = 1887 kJ/kg. The IAPWS-IF97 equation gives h = 2585.77 kJ/kg — a 27% error. The same model with Python code execution (CoolProp) gets the exact answer.
2. Reasoning mode is critical
GPT-5.4 without reasoning: 81.0%. With reasoning: 96.9%. A 16-point jump from enabling chain-of-thought. Reasoning enables cross-checking, self-correction, and more careful interpolation. All models in the leaderboard use their best available reasoning mode.
3. Efficiency ≠ accuracy
Gemini scored #1 with 525 tokens/question average. Claude Opus used 12,981 tokens (25×) and scored lower. More thinking does not necessarily produce better answers for well-defined property lookups.
4. No model is perfect everywhere
Each model has unique weaknesses: GPT-5.4 struggles on inverse lookups (88.3%), Opus on supercritical (48.3%), MiniMax on inverse lookups (63.3%), DeepSeek on hard problems (67.6%). The benchmark discriminates.
5. Tool use changes everything
The same model that scores 48% on supercritical questions without tools scores 100% with Python code execution (CoolProp/IAPWS). The gap isn't knowledge — it's methodology. LLMs know they need equation-of-state solvers but can't run them without tool access.

Ground Truth
All reference values computed with CoolProp 7.2.0 using the IAPWS-IF97 equation of state — the international standard for water and steam properties. CoolProp validated against NIST reference data with maximum deviation of 0.037%.
Quick Start
Evaluate your model
git clone https://github.com/olivenet-iot/ThermoQA
cd ThermoQA
pip install -r requirements.txt
# Run evaluation (choose your provider)
export OPENAI_API_KEY=xxx
python scripts/run_evaluation.py --provider openai --model gpt-5.4 --output results/

LLM-based extraction (recommended)
After running evaluation, re-extract answers using Sonnet 4.6 for robust parsing of any output format:
export ANTHROPIC_API_KEY=xxx
python scripts/reextract.py --provider openai --dry-run # preview changes
python scripts/reextract.py --provider openai # apply
python scripts/reextract.py --all # all providers
Methodology
Evaluation Pipeline
Question (JSONL) → LLM API call → Raw response → LLM Extractor (Sonnet 4.6) → Scorer → Results
- Question delivery: System prompt instructs the model to show reasoning and report answers in
symbol = value unitformat. Each question includes format hints. - Model response: Free-form text. Models can use any format — prose, LaTeX, tables. All reasoning modes (thinking/chain-of-thought) enabled.
- Extraction: LLM-based extractor (Claude Sonnet 4.6, temperature=0) parses the final answer values from the full response including thinking text. This eliminates model-specific regex issues.
- Scoring: Per-property scoring with ±2% relative tolerance OR ±0.5 absolute tolerance (whichever is more lenient). Quality (x): absolute tolerance 0.03. Phase: exact match with alias list.
Why LLM extraction?
Initial regex-based extraction had ~5-15% failure rate depending on model output format (LaTeX subscripts, prose answers, thinking block contamination). LLM extraction reduced this to ~0% while being model-agnostic. We test thermodynamic knowledge, not output formatting.
Scoring
- Property accuracy: fraction of correctly extracted properties within tolerance
- Question score: fraction of correct properties per question
- Mean question score: average across all questions (reported as "Score" in leaderboard)

Competitive Landscape
Only two dedicated thermodynamics benchmarks exist in the LLM evaluation literature:
| Benchmark | Size | Format | Coverage |
|---|---|---|---|
| UTQA (Geißler et al., 2025) | 50 | MCQ | Physical chemistry thermo |
| Loubet et al. (2025) | 22 | Calculation | Ideal gas only |
| ThermoQA (ours) | 110+ | Open calculation | Engineering thermo, real fluids |
ThermoQA is the first benchmark covering applied engineering thermodynamics: steam tables, real fluid properties, supercritical states, and (upcoming) component/cycle analysis.
