LLM
Large Language Model
ELI5 — The Vibe Check
An LLM is a humongous AI that read basically the entire internet and learned to predict what words come next, really really well. So well that it can write code, explain quantum physics, and roast you in three languages. It's autocomplete on steroids with a PhD.
Real Talk
A Large Language Model is a neural network trained on massive text corpora to model the probability distribution of language. They are typically transformer-based, with billions to trillions of parameters, and are capable of text generation, summarization, translation, reasoning, and code synthesis.
When You'll Hear This
"We're integrating an LLM into the support chat." / "That's an LLM hallucination, not a real answer."

Prompt
A prompt is the message you send to an AI to get it to do something. 'Write me a poem about JavaScript' — that's a prompt.
Token
In AI-land, a token is a chunk of text — roughly 3/4 of a word.
