The results rang out like a gunshot. “I’ve never seen a single paper trigger the kind of reactions this one has in the health AI community,” wrote Kaiser Permanente’s vice president of AI and emerging technologies on LinkedIn. The paper’s findings, like all science, are subject to interpretation and debate — but many online reactions treated them more like a clear victory for general frontier models.
