Baichuan AI
Beijing-based AI company selling medical large language models (Baichuan-M series) via API, hospital partnerships and the Baixiaoying consumer app, aimed at healthcare providers and consumers.
Baichuan Intelligence was founded in April 2023 by former Sogou CEO Wang Xiaochuan. It began with open-source and commercial general-purpose LLMs (Baichuan-7B/13B, Baichuan 2–4). In 2025 it restructured around healthcare, and by 2026 it had narrowed its focus to medical AI, including the Baichuan-M3 and M4 models. Its business model is paid medical-model APIs, hospital partnerships and consumer products such as Baixiaoyi. It has raised roughly $1B in total, including a roughly $691M Series A in July 2024 at about a $2.8B valuation. Wang said in January 2026 that it held about RMB 3B in cash and might consider an IPO in 2027.
