The 4 principles I apply with AI (Karpathy-style)


Who Andrej Karpathy is (and why his move to Anthropic is a big deal), and the 4 principles I've drawn from him to make AI save me time rather than waste it.

1. Who is Karpathy (and why it matters)

Hard to find more credibility on the subject. Karpathy co-founded OpenAI, led AI at Tesla, and is above all one of the best educators in AI (his courses and videos have trained a generation). He also popularized the term "vibe coding." In May 2026, he joined Anthropic — when someone of that caliber chooses a house, you pay attention.

A career that summarizes the recent history of AI — and a move that says a lot about Anthropic.

2. The 4 principles (my synthesis, in his spirit)

Honesty first: these are not "Karpathy's official 4 rules." This is my synthesis, inspired by his way of teaching work with agents. The idea matters more than the label:

Four simple habits — it's their consistent application that makes the difference.

3. Why it changes everything

In practice, these principles save you tokens, time, and quality: responses that fit instead of wordy walls, projects that don't go off the rails. My principle #3 ("surgical") isn't theoretical: it was born from a deployment that broke everything because too many things were pushed at once. Since then, every change traces back to one specific request. One mistake, one rule.

Let's talk

These principles resonate?
