How ChatGPT Works: Under the Hood
At its core, ChatGPT uses neural networks trained on massive datasets to predict and generate responses token by token.
-
Prompting Mechanism → Users provide input; reinforcement learning with human feedback (RLHF) refines alignment.
-
GPT-5 Update → Introduces “built-in thinking” for deeper reasoning and fact-grounding.
-
Realtime AI → gpt-realtime allows instant speech-to-speech processing, paving the way for production-ready voice agents.
Even with GPT-5’s breakthroughs, ChatGPT isn’t sentient—it’s a sophisticated pattern engine. Recognizing this boundary is vital as we design AI that augments human intelligence while staying grounded in ethics and accountability.
