|---|---|---|---|---|
| MedQA (USMLE) | 89.2% | 90.2% | 82.0% | 84.1% |
| MedMCQA | 72.8% | 74.1% | 65.3% | 68.0% |
| PubMedQA | 81.4% | 79.1% | 71.2% | 76.3% |
| MMLU Clinical | 88.6% | 87.1% | 79.8% | 82.5% |
Proprietary Benchmarks
Capabilities Only We Can Measure
These benchmarks test capabilities unique to ConceptualHealth.AI. No other model has access to 8-axis structured clinical data, so no other model can be evaluated on these tasks.
| Benchmark * | ConceptualHealth.AI | GPT-4 | Llama 3 70B | MedGemma |
|---|---|---|---|---|
| 8-Axis Cross-Reasoning | 94.7% | N/A | N/A | N/A |
| Temporal Decay Prediction | 91.3% | N/A | N/A | N/A |
| Drug-Outcome Correlation | 88.9% | N/A | N/A | N/A |
* Proprietary benchmarks. No other model has access to 8-axis structured data.
Analysis
What the Numbers Mean
Standard Benchmarks
On standard medical AI benchmarks, ConceptualHealth.AI performs competitively with GPT-4 and significantly outperforms open-source alternatives. This demonstrates that fine-tuning on proprietary clinical data does not degrade general medical knowledge while it adds capabilities that no general-purpose model possesses.
Proprietary Benchmarks
The proprietary benchmarks are where ConceptualHealth.AI is truly differentiated. 8-Axis Cross-Reasoning tests the model's ability to identify clinically significant interactions between health axes. Temporal Decay Prediction evaluates forecasting of health trajectory changes. Drug-Outcome Correlation measures the accuracy of medication response predictions using multi-axis patient context. These are tasks that no other model can even attempt.
Methodology
Standard benchmarks use the published evaluation protocols for each test suite: MedQA uses the 4-option USMLE-style format, MedMCQA uses the AIIMS/JIPMER examination format, PubMedQA uses the yes/no/maybe reasoning format, and MMLU Clinical uses the 4-option multiple choice format across anatomy, clinical knowledge, medical genetics, professional medicine, and college medicine subtasks.
Proprietary benchmarks use held-out clinical data from the NexusOrb platform. Test cases are reviewed by licensed clinicians for clinical accuracy. Evaluation is performed quarterly with each model release.
