MDIA agent achieves high scores on HealthBench Professional benchmark

By PulseAugur Editorial · [3 sources] ·

Researchers have developed MDIA, a Multi-agent Diagnostic Intelligence Agent, which utilizes a 7-node clinical reasoning graph to achieve strong performance on the HealthBench Professional benchmark. When evaluated using OpenAI's GPT-5.4-2026-03-05, MDIA scored 0.6272, surpassing ChatGPT for Clinicians by 3.72 percentage points. The study indicates that architectural design, including specialty routing and context preservation, significantly impacts agentic performance, rather than solely prompt engineering. The choice of grading model also introduces variability, as demonstrated by MDIA scoring 0.6585 when graded by Gemini 2.5 Pro, highlighting the need for multi-grader evaluations. AI

IMPACT Demonstrates architectural improvements in AI agents can significantly boost performance on clinical benchmarks, suggesting a path beyond prompt engineering.
