Prompt engineering is the process of crafting specific inputs or "prompts" for AI models to generate desired outputs. Think of it like asking a question in a way that gets the best answer. The clearer and more detailed the prompt, the better the response from the AI. This technique is widely used in AI applications, like chatbots, image generators, and language models, to improve performance. By mastering prompt engineering, you can optimize AI tools for tasks like content creation, coding help, or problem-solving, making them work smarter for you.
