Gemini 3 makes fewer histopathology misinterpretations than three peers.

Preprint

Four general-purpose LLMs were evaluated on 153 multi-organ pathology cases without training or fine-tuning. Gemini 3 had lower misinterpretation rates than the other three models, while Grok 4.20 had higher fabricated-feature hallucination rates than ChatGPT-5.3 and Gemini 3. [1]

Medical Imaging

AI-ECG detects HCM phenotype and predicts HCM development in sarcomere variant carriers.

Preprint

Among genotype-positive, phenotype-negative individuals, higher AI-ECG scores predicted HCM development during follow-up. In 57,007 UK Biobank participants, AI-ECG and polygenic risk provided complementary information for identifying HCM. [2]

Policy & Governance
