# BioXArena-Pro

BioXArena-Pro replaces biomedical modeling evaluation with 64 research-level tasks rebuilt from published studies, most holding out an entire biological unit such as a species, cohort or cell line, and audited in several rounds to close label leaks. Across 22 agent configurations the best scores 55.1 of 100 and no task saturates; on the nine tasks close to the original studies the strongest agent ties the reproduced published methods (54.9 versus 54.7), while on the 48 rebuilt tasks the methods trail by 8.2 points.
