This page is currently in the making... The goal for this guide is to distill everything you need to know to get started with [Prompt Engineering](https://promptmetheus.com/resources/llm-knowledge-base/prompt-engineering "LLM Knowledge Base: Prompt Engineering") down to a single page. There is no technical knowledge required and all the essential questions will be answered. Once you're done reading, you'll be ready to tackle your first Prompt Engineering project. A few notes: - All technical terms are deep-linked to respective definitions in our [LLM Knowledge Base](https://promptmetheus.com/resources/llm-knowledge-base "Bite-sized explanations for commonly used terms and abbreviations related to Large Language Models and Generative AI"). If you don't know what a certain term means, just click on it and get a bite-sized explanation. - ... Let's start with the basics. ## What is a GPT and how does it work? A [Generative Pre-trained Transformer (GPT)](https://promptmetheus.com/resources/llm-knowledge-base/generative-pre-trained-transformer-gpt "LLM Knowledge Base: Generative Pre-trained Transformer (GPT)") is a specific type of [Large Language Model (LLM)](https://promptmetheus.com/resources/llm-knowledge-base/large-language-model-llm "LLM Knowledge Base: Large Language Model (LLM)") that uses [Deep Learning](https://promptmetheus.com/resources/llm-knowledge-base/deep-learning "LLM Knowledge Base: Deep Learning") to generate human-like text. The best way to understand how a GPT works under the hood is undoubtedly to stop right here and invest 27 minutes of your time in watching is excellent video by [3Blue1Brown](https://www.youtube.com/@3blue1brown "3Blue1Brown YouTube channel"): ## What is Prompt Engineering and why do I need it?
