This tutorial showcases the art of prompt engineering with OpenAI's Text DaVinci 02 model. The speaker delves into a variety of tasks, such as summarizing text with different levels of conciseness and temperature settings, extracting named entities and dates, and rewriting content for diverse audiences, including children and online news readers. The video emphasizes how tweaking prompts with action verbs and vivid adjectives, along with adjusting parameters like temperature, can greatly influence the model's output. This highlights the importance of crafting precise prompts to achieve the desired results effectively.
