A new arXiv study shows OpenEvidence's specialized clinical tool beats top general‑purpose models (Claude Opus 4.8, Gemini 3.1 Pro, GPT‑5.5) on 620 real‑world point‑of‑care questions. Physicians across 30 specialties rated the specialized tool higher on accuracy, utility, source quality, verifiability and completeness.

OpenAI introduces ATHENA-R1, an AI agent for treatment reasoning that outperforms language models and tool-use systems. Trained on 212 biomedical tools, ATHENA-R1 achieves 94.7% accuracy on open-ended drug reasoning and 82.9% on treatment reasoning. This breakthrough has significant implications for the healthcare industry and AI research.

OpenAI introduces IMCBench, a benchmark for multimodal large language models in image-grounded medical conversations, evaluating safety, accuracy, and uncertainty in diagnosis. The benchmark tests eight models, with Claude Opus 4.6 achieving the highest overall score. The results highlight the need for multi-dimensional evaluation frameworks in medical AI.
