River AI lands $1.1B to build personal trainable agents
River AI, founded by ex‑xAI co‑founder Igor Babuschkin, raised $1.1B led by General Catalyst with backers like Nvidia and AMD Ventures. The cash powers a platform that lets developers fine‑tune open‑weight models into personal agents, promising enterprise‑grade reinforcement‑learning runs in minutes without an infra team. This could shift AI from generic task bots to personal “guardian‑angel” assistants.
