LLM
A Large Language Model (LLM) is a neural network, typically based on the transformer architecture, trained on massive amounts of text to predict and generate human-like language. With billions to hundreds of billions of parameters, LLMs learn statistical patterns of grammar, facts, and reasoning from their training…
