LLM (Large Language Model)
Large Language Model — a transformer trained on huge amounts of text to predict the next token, which turns out to be enough to write, summarize, translate, reason, and code. LLMs like Gemini and GPT also power creative workflows: they expand rough ideas into detailed image or video prompts, write song lyrics, and generate scripts. Practically, treat an LLM as a fast, knowledgeable collaborator that occasionally makes things up (hallucination), so verify facts. Example: asking an LLM to turn 'cozy cafe photo' into a rich prompt with camera, lighting, and mood details before generating.
