Andrej Karpathy. A follow-up where Karpathy actually sits in front of ChatGPT, Claude, Gemini and Perplexity and uses them like a power user. Watch this after the article and his "Intro" — you'll see the mental model put into practice in real time, including the small choices (which model, which mode, when to paste vs upload) that separate frustrated beginners from people who get useful answers on the first try.
The workflow habits are stronger than the exact product choices. Re-check current model defaults, file behavior and privacy controls before copying any upload-heavy pattern into client or workplace use.
See how an experienced user switches tools, modes and context strategies while keeping verification in the loop.
Watch or read a basic LLM explanation first so the live workflow does not feel like magic.
