Alibaba Open-Sources Coca Medical Foundation Model
Context that changes how you build, even if there's nothing to install.
On September 18, 2026, Alibaba's DAMO Academy, in partnership with Guangdong General Hospital and Zhejiang University, open-sourced a medical AI model named 'Coca' that demonstrated superior diagnostic performance to most radiologists across 40,000 real-world exams.
Open-sourcing high-performance medical diagnostic tools allows global researchers to build localized health solutions without massive proprietary licensing fees.
This is a significant contribution to the open-source medical AI space, though regulatory hurdles in Western markets will likely limit its immediate clinical adoption. It demonstrates Alibaba's ability to maintain a lead in specialized domain models.
FDA or EMA evaluations of the Coca model's safety and bias metrics.
- Provides developers a high-performance framework for integrating advanced diagnostic capabilities into medical software.
- Validates the utility of large-scale medical foundation models trained on diverse, real-world clinical datasets.
- Signals a broader industry trend toward democratizing access to professional-grade medical diagnostic tools for global researchers.
Multiple partners confirmed the collaboration, and the research was published in the journal Science.
