Large language model
A large language model is a program trained on huge amounts of text to predict and generate language.
What it tells you about a developer
LLM experience on a profile means the developer has built software around a model someone else trained. The engineering work lives in which model they used and what the product did with its answers, not in the model itself.
A large language model, or LLM, is trained on huge amounts of text so it can predict which words come next. It gets that name because the model is large, containing billions of internal settings, and it works on language rather than images or numbers. A developer who builds with an LLM writes code that sends it a prompt and reads back its answer, then decides what to do with that answer.
