🪄 Simple Definition:GPT is the type of AI model that powers tools like ChatGPT — it generates text by predicting what comes next in a sentence.
🌟 Expanded Definition:GPT stands for Generative Pre-trained Transformer.
- Generative → it can create text.
- Pre-trained → it was trained on a massive collection of text before you ever use it.
- Transformer → a special AI design that makes it great at understanding context and word relationships.
Together, these features allow GPT to answer questions, write essays, summarize documents, and more.
⚡ In Action:When you type “Once upon a…” GPT continues with “time” because it has seen that phrase many times and knows it’s the most likely next step.
💡 Pro Tip:Think of GPT as the engine and ChatGPT as the car. Understanding GPT helps you see what’s under the hood.
