Confused by RLHF, Pre-training, and Fine-tuning? We break down the complete medical LLM pipeline and explain how "clinical reasoning" is actually built into AI.

In this definitive guide, we decode the journey of Generative AI in medicine, from raw data pre-training to expert-led reinforcement learning. We explore the mechanics of "Chain of Thought" reasoning, the risks of clinical hallucinations, and why domain-specific fine-tuning is the gold standard for healthcare applications.

Key Takeaways:

• The 3 Stages of AI: Why pre-training is like medical school and RLHF is the "Senior Oversight" phase.

• Safety vs. Utility: How reinforcement learning from human feedback (RLHF) can inadvertently bias clinical results.

• Small Models, Big Impact: The role of model distillation in preserving patient privacy and reducing hospital costs.
