MIA 1, Medical Intelligent Agent
Dr. Max Health · Research release · October 2026
MIA 1 is a 27B clinical reasoning model built on Qwen3.8-27B with Dr. Max Health's clinical reasoning harness and medical tools. It is our first step toward AI that reasons through real clinical cases at the level of an experienced doctor.
Highlights
- Clinical calculations: 86.6% on MedCalc-Bench with its medical tools, within 2 points of Claude Opus 5.5.
- Hard cases: within 4 points of Claude Opus 5.5 on HealthBench Hard.
- Built for clinicians: 54.1 vs 41.3 for its base model on HealthBench Professional, with answers half as long.
- Efficient: 27B parameters, running on a single GPU node.
Results
| Benchmark | MIA 1 | Qwen3.8-27B | Claude Opus 5.5 |
|---|---|---|---|
| HealthBench Professional | 54.1 | 41.3 | 65.1 |
| HealthBench Hard (100-question sample) | 39.8 | 37.6 | 43.8 |
| MedCalc-Bench (accuracy %) | 86.6 (with calculator tools) | 75.7 | 88.2 |
How we evaluated
HealthBench Professional (325 held-out examples) and HealthBench Hard (100-question sample): scores are length-adjusted following the HealthBench Professional paper and are the mean of two blind model graders (Qwen 27B and Claude Opus 5.5) using the official rubrics; per-grader and raw scores are in the technical report. MedCalc-Bench (1,100 test items): scored by exact answer with the same rule for every model; MIA 1 uses its calculator tools and its score is the average over 8 answers per question, Claude Opus 5.5 and Qwen3.8-27B answer without tools (Opus 1 answer per question). All models were run by Dr. Max Health on the same questions. These internal results are not comparable to official HealthBench leaderboard numbers. Technical report to follow.
Intended use
MIA 1 is released for research and evaluation. It is not yet a certified medical device; we are working toward clinical decision support that meets medical-device requirements.
