The Best AI for Doctors in 2026 (Gemini vs Perplexity vs Claude)

I have 2 months left before Housemanship starts. The "Limbo" is ending, and I need to sharpen my clinical brain fast.
But here is the problem: Most doctors are either scared of using AI or they are using it wrong. Relying on basic ChatGPT for diagnosis is a recipe for disaster. But ignoring AI completely? That is just inefficiency.
In this video, I ran an A/B test on the heavy hitters—Gemini 3 Pro, Perplexity, and Claude Sonnet 4.5 (with Extended Thinking). I broke them down by clinical accuracy, hallucination risks, and the one thing nobody talks about: Token Limits.
If you are a medical student or clinician trying to save time without killing a patient, this is the only stack you need.
