Baichuan's Last Co-Founder Exits as Firm Goes All-In on AI Healthcare

KEY FACTS

In July 2026, Ru Liyun, the last remaining co-founder of Baichuan Intelligence, formally resigned.
Ru Liyun had opposed abandoning general-purpose models and advocated focusing investment on coding scenarios.
In April 2025, Wang Xiaochuan overrode objections and decided to narrow the company's front, betting entirely on AI healthcare.
The company's team has been cut to under 300 people, with a flattened hierarchy to focus on the new direction.

PHYSIX OBSERVATION

Baichuan's pivot reflects the existential anxiety of large-model startups caught in the compute arms race. Abandoning the general-purpose track avoids being strangled by the giants, but moving into vertical healthcare means shifting from technological competition to competition over resources and regulatory barriers. At a time when coding has become the most certain path to AI deployment, this decision looks contrarian and lonely; its success will depend on whether the company can build a genuine clinical-data moat over a long cycle, rather than breaking through on model capability alone.
