Introduction

This video provides a comprehensive guide to prompt engineering, focusing on techniques to extract the best results from large language models (LLMs). The speaker, Bruno Picinini, draws on his experience and research from numerous scientific articles and real-world applications to teach viewers how to create effective prompts, ranging from simple to highly complex. The video is structured in modules, progressing from fundamental concepts to advanced techniques.

Key Takeaways

• Prompt Engineering Defined: Prompt engineering is the empirical science of planning, creating, and testing prompts to get better responses from LLMs. It's a crucial skill for unlocking the full potential of LLMs across various applications.
• The P.R.O.M.P.T. Structure: A framework for creating more complex prompts, encompassing Persona, Roteiro (script), Objetivo (objective), Modelo (model), Panorama (context), and Transformar (transform/iterate).
• Prompting Techniques: The video covers various techniques, including Zero-Shot, Directional Prompting, Few-Shot, Chain-of-Thought, Contrastive Chain-of-Thought, Self-Consistency, Tree-of-Thought, and Thought-Skeleton. These techniques are explained with examples and their effectiveness is compared.
• Avoiding Hallucinations: Strategies to minimize inaccurate or fabricated responses from LLMs are detailed, including using system prompts, providing clear instructions, requesting citations, and adjusting temperature settings.
• Practical Applications: The video demonstrates practical applications of prompt engineering through examples, including creating interactive menus, generating landing pages, and building sophisticated agents. The speaker also shares his experience building and refining prompts for various tasks.
