Reinforcement Learning from Human Feedback (RLHF) in LLMs
Step 1: Prompt Generation
β Think of this as a teacher giving assignments
β The pretrained LLM is asked different questions (prompts)
Step 2: LLM Response Generation
β The student (LLM) writes multiple answers
β Example: Answer A β Answer B β Answer C
β Some are good, some are weak, some are off-topic
Step 3: Human Feedback & Ranking
β Teachers (humans) grade and rank the answers
β Best answer gets top marks, weaker ones get lower marks
β Example: A > B > C
Step 4: Reward Model Training
β Instead of teachers grading forever, we train a teaching assistant (reward model)
β This assistant learns the grading style of teachers
β Now it can quickly score new answers without human effort every time
Step 5: Policy Optimization (PPO Fine-Tuning)
β The student (LLM) now practices with the teaching assistantβs feedback
β Uses Proximal Policy Optimization (PPO) to improve step by step
β Learns how to write answers closer to what teachers want
Step 6: Improved LLM
β The student (LLM) becomes more aligned, helpful, and safer
β No longer just smart, but also well-behaved and human-friendly
Flow from the Diagram
Prompt (assignment)
β LLM Responses (student answers)
β Human Ranking (teacher grades)
β Reward Model (teaching assistant)
β PPO Fine-Tuning (guided practice)
β Aligned LLM (improved student)
