Baichuan releases “M2Plus”, an Proof-Augmented Medical Mannequin Billed as a “ChatGPT for Medical doctors”

On Oct. 22, 2025, Chinese language AI lab Baichuan unveiled Baichuan-M2Plus, a healthcare-focused giant mannequin and the most recent step in its medical stack, alongside an upgraded companion app and open API entry. The corporate positions M2Plus as a “physician’s ChatGPT,” optimized for medical reasoning and evidence-grounded solutions.

Baichuan says M2Plus introduces a six-source Proof Augmented Reasoning (EAR) framework that synthesizes authentic research, proof evaluations, medical tips, apply know-how, public well being training supplies, and regulatory real-world knowledge. In inside evaluations, the mannequin reportedly exhibits a considerably decrease hallucination price than general-purpose LLMs—about thrice decrease than DeepSeek’s medical product—and “even surpasses” the favored U.S. medical app OpenEvidence on the corporate’s exams.

The discharge follows Baichuan’s open-sourcing of Baichuan-M2 in August and is framed as a push towards safer medical determination help and patient-facing Q&A. With the API now open, hospitals, well being platforms and builders can combine M2Plus into triage assistants, guideline retrieval, coding/claims workflows, and medicine counseling, in keeping with the announcement.
