If you’ve worked with LLMs, you’ve seen this problem:
They sound confident. But they’re often wrong.
That’s because they don’t “know” things. They predict text.
RAG (Retrieval-Augmented Generation) is one of the most practical ways to fix this.
Instead of relying on memory, it:
Retrieves relevant information
Feeds it into the model
Generates answers based on that
In this guide, we build a RAG system step by step using Python:
Creating embeddings
Storing them in a vector database
Retrieving relevant chunks
Generating answers with context
We also explore:
When RAG is the right choice
How to improve accuracy
Why chunking strategy matters more than model size
If you’re learning AI engineering, this is one of the most important systems to understand.
