🤖 What is GenAI (Generative AI)?
Generative AI is a type of artificial intelligence that can create new content — like text, images, code, music, and more.
Instead of just analyzing or classifying data, GenAI generates original outputs based on what it has learned.
✏️ Examples of GenAI:
ChatGPT → Generates text and answers questions
DALL·E → Creates images from text prompts
GitHub Copilot → Suggests code automatically
In short, GenAI helps machines create like humans do.
🔍 What is RAG (Retrieval-Augmented Generation)?
Sometimes AI models don’t know everything — or they make up facts (we call this "hallucination").
RAG is a method that improves AI responses by retrieving real documents before generating an answer.
🛠️ How RAG works:
AI retrieves relevant documents from a database
It generates an answer using that info
This makes the response more accurate and up-to-date.
🖥️ What is an MCP Server?
MCP = Model Control Plane
An MCP Server is a tool that helps manage, deploy, and control AI models.
Think of it like a traffic controller that:
Deploys different versions of models
Routes tasks to the right model
Scales the infrastructure
Monitors usage and performance
This is especially useful when running multiple AI models in production.
🧠 What is an LLM (Large Language Model)?
An LLM is a type of AI model trained on huge amounts of text to understand and generate human-like language.
✏️ What LLMs can do:
Chat with users
Summarize documents
Write essays or code
Translate languages
⚡ Examples of LLMs:
GPT-4 by OpenAI
Claude by Anthropic
LLaMA by Meta
LLMs are the engine behind most GenAI apps today.
✨ Quick Recap
Term What it means (in simple words)
GenAI AI that creates text, images, code, etc.
RAG AI that looks up real info before answering
MCP Server Manages and deploys AI models smoothly
LLM A powerful AI model that understands language
🙌 Final Thoughts
These four concepts — GenAI, RAG, MCP Server, and LLMs — are shaping the future of how we build smart applications.
I’m just starting my journey in this space, but learning these terms gave me a solid foundation.
