MedCalc-Pro: Solving Complex Medical Calculations with LLM Agents

arXiv:2607.02879v1 Announce Type: new Abstract: Current benchmarks for evaluating large language models (LLMs) in medical calculation are largely based on simplified settings, where each patient case corresponds to a single calculator and the required tool is explicitly specified in the query. However, real clinical scenarios often require multiple calculators for joint evaluation, nested-scale calculation, and fuzzy queries that do not directly specify the target calculator. To this end, we propose a new medical calculation benchmark, MedCalc-Pro, which covers three progressively challenging

Why this matters
Why now

The rapid advancement of large language models (LLMs) is pushing their application into increasingly complex and sensitive domains like medical calculations, necessitating more robust evaluation benchmarks.

Why it’s important

Improving the capability of LLMs to handle complex, real-world medical calculations is critical for their eventual adoption in clinical settings and for enhancing diagnostic and treatment support systems.

What changes

The introduction of MedCalc-Pro provides a more sophisticated benchmark, challenging LLMs beyond simplistic scenarios and accelerating the development of more practical AI agents for medical use.
