At a high level, large language models learn to understand and generate language through a process called unsupervised learning. Here’s a simplified explanation of how they operate:

Training on Massive Datasets: LLMs are trained on vast amounts of text data sourced from books, articles, websites, and other publicly available content. During training, the model reads through this text and learns to recognize patterns, relationships, and structures in language. This is done through a process called tokenization, where the model breaks text down into smaller chunks (called tokens) like words, subwords, or even characters.
Learning Context and Relationships: Using transformers, LLMs analyze the relationships between words and phrases, not just in isolation, but in context. For example, they understand that "apple" in the sentence "I ate an apple" is a fruit, while "Apple" in "I use an Apple laptop" refers to a brand. Transformers enable the model to attend to all words in a sentence simultaneously, capturing context more efficiently than earlier models.
Building a Language Representation: As the model is exposed to more and more text, it learns complex patterns, such as grammar, sentence structure, tone, and even the intent behind phrases. The model doesn’t “understand” language in the same way humans do, but it is excellent at predicting what comes next in a sentence based on what it has seen during training.
Generating Responses: Once trained, the model can generate coherent and contextually relevant text. For instance, when given a prompt, LLMs predict the most likely sequence of words or sentences that follow, generating responses that are contextually appropriate. This is why models like GPT-3 can write essays, answer questions, or even hold conversations that seem remarkably human-like.
