LLM Temperature and top_p Explained Without the Math

Temperature and top_p control randomness in LLMs. No probability theory needed. Just practical intuition and how to tune them.

RAG Chunking: Why Chunk Size Is Everything

RAG breaks documents into chunks. But what chunk size? Too small and context is lost. Too large and semantic search fails. Here's how to pick.

System Prompts: The LLM Feature Most People Ignore

System prompts are your secret weapon. How they work, why they matter more than you think, and 5 patterns that actually change model behavior.

LLM Quantization: Q4_K_M Isn't Always the Best Choice

Q4_K_M is the default, but it's not magic. When Q3, Q5, or Q6 makes sense. How to benchmark quantization tradeoffs on your hardware.

Context Window vs Token Limit: Not the Same Thing

What's the actual difference between context window and token limit? Why one model says 8K and another says 128K. A practical breakdown.
