Karpathy didn't make a course.
He made THE course.
3 hours. Free.
Tokenization. Attention. Hallucinations. Tool use. RLHF. DeepSeek. AlphaGo.
Every behavior you've ever wondered about in an LLM - where it comes from, why it exists, how it was engineered.
The gap between engineers who understand this and engineers who don't isn't technical depth.
It's the ability to conceive of entirely different things.

Only three hours? My imposter syndrome was expecting at least a decade of self-doubt.

Karpathy always delivers value

The course is 1 y.o., cool but much outdated already

felt that way after watching the first section. moving from just treating it as a black box to knowing how the internals actually fit together is a massive mindset shift for building anything meaningful.

the line about conceiving different things lands hard. engineers who studied karpathy design with the failure modes baked into the architecture, the rest design around them and call it scope

Yeah, the way he breaks down attention mechanisms is unreal. Itβs dead simple once you see it through his lens but most papers just bury you in jargon.

the most underrated part of that course is the persistent memory section. karpathy frames it as a solved problem but the hard part β who curates the wiki when the model writes bad entries β doesn't get 3 hours.

Karpathy is the one that truly believe in an Open access to AI for everyone and always doing something about it

yeah, itβs insane... he really spoiled us for free.
