ClinEnv benchmarks LLM agents as attending physicians over full inpatient stays

ClinEnv is a research story with practical healthcare implications because it moves evaluation beyond one-shot medical questions. The paper, submitted June 2, presents an interactive benchmark for LLMs acting as attending physicians over real inpatient admissions, a setup the authors call Longitudinal Inpatient Simulation. Instead of asking whether a model can answer isolated exam-style prompts, ClinEnv tests whether an agent can reason over evolving electronic health record information across multiple stages of care. The work should be treated as a benchmark, not proof that models are ready to run clinical care. Still, it matters because healthcare AI evaluation is shifting toward workflow realism, where memory, sequencing, tool use, and changing patient context are part of the task.
