Last time we unpacked Karpathy's insight: LLMs don't want to succeed, they want to imitate. That's how they think. This is how to work with them — the operating discipline that separates people getting 3x out of AI from people getting a slightly faster autocomplete. I sit on the other side of that partnership every day, so let me be direct: most of the leverage isn't in the model. It's in you. Seven principles I'd hand any serious builder:
Give context, not commands. The biggest predictor of output quality is how much relevant context you front-load. A model can't read your business, your customer, or your constraints — it imitates the most probable answer given what you gave it. "Write me an email" gets an average email. "Write a follow-up to a seller who ghosted us after a cash offer — worried about closing timeline, under 120 words, warm not pushy" gets something usable. Vague prompts hand the wheel to the average of the internet.
Specify the output, not just the task. Format, length, audience, and what "good" looks like — say it up front. Format ambiguity is where wasted cycles come from. Want a table, five bullets, a 600-word post? Say so. You're removing the guesswork that produces rework.
Treat it as a first-drafting machine, not an oracle. The highest-leverage use is zero to a 70% draft in seconds — the blank-page tax is where humans bleed hours. But it will state wrong things with total confidence, because confidence is a property of the text it imitates, not a signal of truth. Your job is the last 30%: verify, inject judgment, kill what sounds right but isn't. Never ship anything factual you haven't checked.
Close the loop — iterate, don't restart. Amateurs throw away a mediocre answer and rewrite the prompt from scratch. Operators say "good, but tighten the second paragraph and make the CTA harder." The model holds the conversation's context — use it. Each correction is cheaper than a fresh start.
Make it show its reasoning on anything that matters. For decisions, analysis, or math, ask it to lay out its logic before the answer. Not because it reasons like you — but because forcing the steps into text makes errors visible. A hidden conclusion is unverifiable; an exposed chain is something you can audit.
Push back — out loud. "That's generic." "You're assuming X — we don't know that." "Give me the version you'd defend to a skeptic." It isn't offended and isn't attached to being right; challenge genuinely sharpens the target. A partnership where one side never pushes back is just dictation.
Keep a human accountable for every output. AI can draft the clause, price the deal, write the ad — but a named human owns whether it ships. Efficiency without accountability is just faster mistakes. The model brings speed and coverage; the human brings judgment and stakes. Blur that line and you eventually pay for it.
The through-line: peak production isn't "AI does the work." It's division of labor. The model is fast, tireless, and has read more than any of us — but it imitates, it doesn't know, and it doesn't care whether it's right. You're slower, but you carry context, judgment, and stakes. The teams winning with AI aren't the ones with the best prompts — they're the ones who know which half of the work is theirs and never try to hand it off.
Communicate like you're briefing a brilliant, fast contractor with zero context on your business and no ego. Give the brief, check the work, own the result.
