AI doctor agent uses reinforcement learning for proactive medical consultations

Researchers have developed DoctorAgent-RL, a novel multi-agent reinforcement learning framework designed to improve AI's capabilities in real-world clinical consultations. This system trains a doctor agent, utilizing the Qwen2.5-7B-Instruct model, to proactively gather patient information through strategic questioning rather than relying on static, single-turn interactions. Evaluations, including blinded human assessments and trials with actual patients, demonstrated that DoctorAgent-RL achieved a 70% exact diagnostic match rate, outperforming existing frontier models.
