Baichuan-M3 Plus

Baichuan-M3 Plus is Baichuan AI's medical vertical large model focused on serious healthcare settings.

It supports evidence-enhanced medical Q&A, clinical decision assistance, and medical education, using proprietary evidence-anchoring so each conclusion is tied to the original paper evidence passage.

With a reported hallucination rate of 2.6% (described as the lowest globally) and API costs 70% lower than the previous generation, it shows that relatively low-cost models can still deliver high performance in rigorous medical workloads.
