Reinforcement Learning from Human Feedback (RLHF) in LLMs

Step 1: Prompt Generation

→ Think of this as a teacher giving assignments
→ The pretrained LLM is asked different questions (prompts)

Step 2: LLM Response Generation

→ The student (LLM) writes multiple answers
→ Example: Answer A → Answer B → Answer C
→ Some are good, some are weak, some are off-topic

Step 3: Human Feedback & Ranking

→ Teachers (humans) grade and rank the answers
→ Best answer gets top marks, weaker ones get lower marks
→ Example: A > B > C

Step 4: Reward Model Training

→ Instead of teachers grading forever, we train a teaching assistant (reward model)
→ This assistant learns the grading style of teachers
→ Now it can quickly score new answers without human effort every time

Step 5: Policy Optimization (PPO Fine-Tuning)

→ The student (LLM) now practices with the teaching assistant’s feedback
→ Uses Proximal Policy Optimization (PPO) to improve step by step
→ Learns how to write answers closer to what teachers want

Step 6: Improved LLM

→ The student (LLM) becomes more aligned, helpful, and safer
→ No longer just smart, but also well-behaved and human-friendly

Flow from the Diagram

Prompt (assignment)
→ LLM Responses (student answers)
→ Human Ranking (teacher grades)
→ Reward Model (teaching assistant)
→ PPO Fine-Tuning (guided practice)
→ Aligned LLM (improved student)
