GPU Memory Math: Will This Model Actually Fit?
Before you download a 70B model, calculate if it fits. The formulas, the gotchas, and a quick calculator you can actually use.
All the articles with the tag "llm".

RAG is the default answer for giving LLMs access to documents. But chunking, embedding, and retrieval introduce failure modes that a virtual filesystem sidesteps entirely.
Google's Gemma 4 is the best open model they've shipped yet. Here's how to pull it, run it, and actually use it for real work with Ollama on your own hardware.
1-bit models store weights as -1, 0, or 1. That sounds insane until you see them run a 100B parameter model on a laptop CPU. Here's what's actually happening.
AMD finally has a fast, open source local LLM server that uses both GPU and NPU. If you've been jealous of Nvidia users, Lemonade is worth your time.
JSON mode forces models to output valid JSON. When it's a lifesaver vs. when it's overkill and makes the model worse.
Temperature and top_p control randomness in LLMs. No probability theory needed. Just practical intuition and how to tune them.
vLLM, llama.cpp, and Ollama all run local LLMs, compare throughput, memory use, GPU support, and which fits your hardware.
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 are your secret weapon. How they work, why they matter more than you think, and 5 patterns that actually change model behavior.
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.
Ollama can load one model at a time on limited hardware. How to switch between models, use CPU offloading, and manage VRAM intelligently.
