🪄 Simple Definition: A Large Language Model (LLM) is an AI that has been trained to understand and generate human-like text.
🌟 Expanded Definition: An LLM is a type of AI built by training on massive amounts of text data (books, articles, websites). It learns patterns in language — how words and ideas connect — so it can answer questions, explain concepts, or even write stories. It doesn’t “think” like a human, but it can imitate conversation and knowledge in useful ways.
⚡ In Action: When you ask ChatGPT a question, the LLM inside it predicts the most likely next words to form a meaningful answer.
💡 Pro Tip: Don’t get stuck on the word “large.” It simply means the model was trained on a lot of data and has many parameters. More data and parameters usually mean smarter, more flexible answers.
