About this API
Baichuan Intelligence was founded in 2023 by former Sogou CEO Wang Xiaochuan — one of China's so-called 'six small tigers' of LLM startups. The company has released Baichuan, Baichuan2, Baichuan3, and Baichuan4 series; the Baichuan2 lineup (7B / 13B / 192K long-context) was open-sourced under permissive commercial terms and quickly became a workhorse Chinese open-source LLM. Commercial APIs are served via platform.baichuan-ai.com with OpenAI-compatible endpoints. Wang Xiaochuan's stated strategic focus is medical AI, with the dedicated Baichuan-M vertical line. General-purpose performance targets GPT-4 / Qwen-Max, with particular strength on Chinese tasks; overseas reach and English performance trail Alibaba.
