Note: Rules Matter!

🧪 Science of GenAI Prompting – Basics

🔹 What is Prompting in GenAI?

Prompting is the method of giving instructions to a Generative AI model (like ChatGPT) in the form of text, examples, or context so that it produces the desired output.
👉 In simple terms: Prompts are the questions or commands we give to GenAI.

🔹 Why Do We Need Prompting for GenAI?

• GenAI models don’t “know” what you want unless you guide them.
• The quality of the output depends on the clarity of your input.
• Prompting helps control tone, format, depth, and accuracy of responses.
• It bridges the gap between human intent and AI output.

🔹 Disadvantages if We Don’t Know Prompting Well

• Outputs may be vague, irrelevant, or too generic.
• Higher chance of hallucinations (AI making up facts).
• Wasted time refining results.
• Limited ability to use GenAI for complex tasks.

3. References – Add examples or style to guide output.
   • Example: “Here’s a style sample: ‘Ghilli is a thrilling sports-action film that mixes humor with action.’
     Now review Leo in the same style.”
4. Evaluate – Check if the AI’s output matches what you need.
   • Example: Did it capture Vijay’s screen presence, dialogues, and fan moments?
5. Iterate – Refine the prompt for improvements.
