A prompt is not a conversation. It's a component contract.

Most of us use LLMs by trial and error. This post gives you a structure: the building blocks of an LLM, and a reusable template for writing production prompts. What is an LLM? Foundation models are very large models pretrained on internet-data; that's what builds Generative AI. With a foundation model, you can adapt one pretrained model to many tasks. A Large Language Model (LLM) is a foundation model for text, and at its core, the same FM can be used for many tasks: summarisation, classification, translation, code generation.
