An LLM is a type of AI model that’s been trained on a massive amount of text data from the internet. It doesn’t truly “understand” in the human sense. Instead, it works by predicting the most likely next word in a sequence.

The core technology behind most modern LLMs is the Transformer architecture. This allows the model to pay attention to different parts of the input text to generate a coherent response.

So, when you ask an LLM a question, it’s not thinking; it’s using the patterns it learned from billions of text examples to generate a highly plausible and relevant answer, word by word.
