What chunk size should I use?

For most RAG applications, 200-500 tokens per chunk works well. Smaller chunks improve precision but may lose context; larger chunks preserve context but reduce retrieval accuracy.

Why does overlap matter?

Overlap ensures that information at chunk boundaries isn't lost. A 10-20% overlap helps maintain context continuity between adjacent chunks.
