What is ChatGPT?

ChatGPT is an AI-powered chatbot developed by OpenAI that can:

✅ Answer questions in natural language
✅ Write essays, emails, and code
✅ Summarize long articles
✅ Generate creative stories & ideas

Key Facts:

  • Launched in November 2022 (GPT-3.5)

  • Latest version: GPT-4 Turbo (faster & smarter)

How Does ChatGPT Work?

ChatGPT is built on a Large Language Model (LLM) trained on:

  • Books, articles, and websites

It doesn’t "think" like humans—it predicts the next word based on patterns.

(Example: If you ask "How to make coffee?", it generates steps based on data it’s seen.)
