👉 Different tools are designed for different purposes.

✍️ Prompt Engineering Basics

One of the most important skills in Generative AI is writing effective prompts.

✅ Simple Prompt Formula

Role + Task + Context + Output Format

Example:

Act as a software tester. Generate login test cases for an e-commerce website. Include edge cases. Output in table format.

🎯 Tips for Better Prompts

❌ Weak Prompt

“Explain AI”

✅ Better Prompt

“Explain Generative AI in simple terms for beginners with real-world examples.”

💡 Key Prompt Engineering Tips

✔ Be specific
✔ Mention audience
✔ Define output format
✔ Add constraints
✔ Refine prompts iteratively

⚙️ Important Generative AI Concepts

Understanding these terms is important for long-term growth.

🔹 LLM (Large Language Model)

Models trained on huge datasets to understand and generate human-like text.

Examples:
• GPT
• Gemini
• Claude

🔹 Tokens

AI processes text in smaller chunks called tokens.

Longer prompts = more tokens used.

🔹 Fine-Tuning

Training a pre-built AI model on custom data to improve specific tasks.

🔹 RAG (Retrieval-Augmented Generation)

A technique where AI retrieves external information before generating responses.

Used in:
✔ AI chatbots
✔ Enterprise AI systems
✔ Knowledge assistants

🔹 AI Agents

AI systems that can:
• Plan tasks
• Execute workflows
• Use tools automatically

AI agents are becoming one of the biggest trends in 2026.
