Organic Chemistry is the hardest reportable subcategory.
58.3% mean correctness.
Where GPQA remains difficult
Aggregate question difficulty across 243 accepted configurations,
without publishing prompts, answer keys, or a model-by-question matrix.

These controls preview a future, separately reviewed question-analysis release. This release intentionally publishes one aggregate cohort only.
Displayed statistics require ≥5 questions and ≥5 configurations.
1. Difficulty by domain
Each configuration is weighted equally. Repeated attempts reduce to one per-question mean before aggregation.
2. Subcategories with enough questions to report
4 subcategories suppressed: fewer than 5 questions| Subcategory | Questions | Mean correctness | Value |
|---|---|---|---|
| Astrophysics | 13 | 71.7% | |
| Chemistry (general) | 19 | 69.8% | |
| Electromagnetism and Photonics | 6 | 71.9% | |
| High-energy particle physics | 14 | 82.7% | |
| Molecular Biology | 14 | 70.5% | |
| Organic Chemistry | 68 | 58.3% | |
| Physics (general) | 18 | 78.1% | |
| Quantum Mechanics | 25 | 81.8% | |
| Relativistic Mechanics | 6 | 83.2% |
3. Consistently difficult patterns
Difficulty remains broad.
The release does not expose Record IDs or per-model correctness.
Descriptive, not causal.
These aggregates do not identify why a configuration failed a question.
4. Question disclosure boundary
Included in this release
Domain/subcategory aggregates, counts, definitions, cohort scope, and suppression markers.
Held back pending dedicated review
Record IDs, per-model correctness, prompt text, choices, keys, completions, and reasoning.
