Features
All amounts are Chinese yuan (CNY), not yen or US dollars. M3-Plus and M2-Plus charge for tokens across all conversation stages and also trigger medical searches at CNY 0.03 per call. Web search, embeddings, and knowledge storage have separate fees. The regular CNY 80 new-customer credit lasts 3 months; it does not make paid models permanently free.
Context is model-specific: M and Baichuan4 API entries list 32k, while Baichuan3-Turbo-128k lists 128k. Billing is proportional to tokens, not rounded up to complete 1,000-token blocks. API prices are not Baixiaoyi subscription prices or assurances of medical accuracy.
The Hai Na Bai Chuan program offers permanently free M3-Plus only after approval for institutions serving medical professionals. It permits real clinical decision support and medical education, not data production; provider attribution and other conditions apply. Search charges and specific allowances within this special program are not separately stated. This is not a generally available free API plan.
