ChatGPT is an AI language model by OpenAI that talks like humans.It answers questions, writes text, and even helps you code — all using Artificial Intelligence.
What Does GPT Mean?
GPT = Generative Pre-trained Transformer– Generative: Creates new text– Pre-trained: Trained on huge data– Transformer: Understands language context
Why Learn How ChatGPT Works?
Knowing how ChatGPT works helps you:-Use AI tools smarter-Build trust in technology-Improve writing, coding, and research
Step 1: Pre-Training
ChatGPT learns from tons of internet text — books, blogs, and more.It predicts the next word in a sentence to learn language naturally.Example: “The sun rises in the…” → “east.”
Step 2: Transformer Architecture
The Transformer is ChatGPT’s brain.It looks at every word’s meaning in context — not just left to right — making its responses accurate and logical.
Step 3: Fine-Tuning with Human Feedback
After pre-training, humans help fine-tune ChatGPT using RLHF (Reinforcement Learning with Human Feedback).This makes it safer, smarter, and more human-like.
Step 4: Tokenization
ChatGPT breaks text into small parts called tokens.Example: “ChatGPT is cool” → “Chat”, “G”, “PT”, “is”, “cool.”That’s how it processes every sentence efficiently.
Step 5: Generating Responses (Inference)
When you type a question, ChatGPT analyzes your input and predicts the best next word — one by one — in milliseconds!That’s what makes chatting feel instant.
Step 6: Adding Personality (Temperature)
Temperature settings control ChatGPT’s creativity:-High = Creative & random-Low = Focused & factualThat’s how it adapts to your tone.
Step 7: Continuous Learning (Truth Check)
ChatGPT doesn’t learn in real time.It doesn’t remember your chats unless memory is enabled.This ensures privacy and consistency.
