Fixed-Size Chunking in RAG: Still Relevant in 2026?
Chunking is the process of splitting documents into smaller retrievable units before embedding and indexing them.
In a RAG pipeline:
Documents are split into chunks.
Each chunk is converted into embeddings.
The embeddings are stored in a vector database.
User queries retrieve the most relevant chunks.
The retrieved chunks are passed to the LLM as context.
This means retrieval quality depends heavily on chunk quality.

Why Fine-Tuning Alone Isn’t Enough: Enter RAG
A fine-tuned model can become much better at understanding domain-specific language, following certain workflows, or generating responses in a particular style.
Traditional fine-tuning approaches tried to push knowledge into the model.
RAG flips the approach completely. Instead of permanently storing information inside model weights, RAG allows the AI to retrieve relevant information dynamically at runtime.

The Part of RAG Nobody Talks About: What Happens Before the LLM Generates an Answer
When people talk about RAG systems, the conversation tends to focus on the same things: which LLM to use, how to write a better prompt, which vector database to choose, how to reduce API latency. Those are real concerns. But there is a quieter layer that gets overlooked almost every time. What happens to your documents before a query is ever asked? The answer to that question determines more about your system quality than almost any other decision. And yet it is the part of R

Why Hybrid Search and Re-Ranking Is the Retrieval Skill Every AI Developer Needs
Most developers building with LLMs focus on the model. They tune prompts, swap models, and experiment with temperature settings. But the most common reason a RAG system gives a wrong answer has nothing to do with the LLM; it is because the right document was never retrieved in the first place. At CodersArts AI, our Hybrid Search and Re-Ranking: From Retrieval to Reliable Answers course is designed to help learners understand why pure vector search breaks and how to fix it u

The Quiet Backbone of Reliable AI Systems: Understanding Chunking in RAG
When people talk about building AI systems today, the conversation usually revolves around: Which LLM to use How to write better prompts Which vector database is fastest Which framework to choose These are important decisions. But there’s a quieter layer in the stack that often gets overlooked — and yet, it has a disproportionate impact on system performance. That layer is chunking . What Is Chunking, Really? At a surface level, chunking is simple. You take a document and spl
