On the morning of January 22, at the "Baichuan-M3 Plus Model Release Media Communication Conference," Baichuan Intelligence, following the open-sourcing of its new-generation medical large model Baichuan-M3 just nine days prior, unveiled the Baichuan-M3 Plus model (abbreviated as M3 Plus). The company announced significant enhancements in the accuracy and reliability of medical question-answering compared to the M3 model, once again setting a new world record for low hallucination rates in medical models.

Reportedly, the M3 Plus model achieved a substantial reduction in hallucination rates compared to the previously released M3 model. In the Hallucination Rate evaluation, the rate dropped from 3.5% for M3 to 2.6% for M3 Plus. During a live demonstration, Baichuan Intelligence compared several leading domestic AI medical model products. The results indicated that while competing products exhibited varying degrees of confusion in citing sources and using professional expressions, Baixiaoying, which is integrated with M3 Plus, delivered the most accurate answers.

Furthermore, the M3 Plus model addresses the challenge of high model costs by implementing a 70% reduction in API calling prices, thereby removing a major barrier to large-scale adoption.
