Why AI Can't Count the R's in "Strawberry" — 7 Mental Models (Karpathy's Masterclass, Simplified)

The most advanced AI on earth can't reliably tell you how many R's are in "strawberry," and it'll insist 9.11 is bigger than 9.9. Yet it can write code and pass the bar exam. Why? OpenAI co-founder Andrej Karpathy spent 3 hours and 31 minutes explaining exactly how these machines work — and underneath it all are 7 simple mental models. I watched the whole thing and distilled it into plain English. Get these seven ideas and you'll understand why AI does the weird things it does — and how to get dramatically better answers out of it. 🧠 Comment "MENTAL" and I'll send you the free 7 Mental Models Cheat Sheet (all 7 + the exact copy-paste prompts). Or grab it here 👉 https://hyperautomationlabs.co/free/m... The 7 mental models: 1. It's a lossy zip of the internet — a pattern machine, not a database 2. It sees tokens, not letters — so never trust it for spelling or exact math 3. It needs words to think — let it reason step by step 4. Its memory is fuzzy, but its desk is sharp — paste your sources in 5. It hallucinates because it was trained to always answer — use tools and verify 6. It doesn't know who it is — its rules come from a hidden system prompt 7. The newest models learn like AlphaGo — use reasoning models for hard problems Credits & source: • This is an independent, credited summary of Andrej Karpathy's "Deep Dive into LLMs like ChatGPT" (YouTube).
