**Rahul** @sairahul1 [2026-04-25](https://x.com/sairahul1/status/2047955648357576920)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.

**Azael** @theazaelov [2026-04-25](https://x.com/theazaelov/status/2048007327345733979)Yeah, the way he breaks down attention mechanisms is unreal. It’s dead simple once you see it through his lens but most papers just bury you in jargon.
