AI engineering, explained properly.
Deep dives on making AI systems smaller, faster, and cheaper — theory, math, code, and receipts.
The Open-Book AI
A plain-English series on RAG — the idea that turns forgetful chatbots into experts on your stuff. No code, one metaphor per article, honest about where it breaks. Start here.
