Large Language Model (LLM)

A Large Language Model (LLM) is the AI technology that powers tools like ChatGPT, Claude, and Gemini. LLMs are trained on massive amounts of text data — books, websites, code, conversations — and learn to predict and generate human-like text. They don't "understand" language the way humans do, but they're remarkably good at producing relevant, coherent responses to prompts.

The "large" in LLM refers to the number of parameters (the internal variables the model uses to make predictions), which can range from billions to trillions. Larger models generally produce better results but require more computational resources to run.
