Karpathy's GPT tutorial remains top entry point

This is Andrej Karpathy’s free educational tutorial from his Zero to Hero series, where he walks through building a GPT-style language model from an empty file, line by line. It is not a commercial product launch; it is a deep-dive learning resource aimed at developers and ML learners who want to understand tokenization, training, sampling, and the core mechanics behind GPT models.

// ANALYSIS

Hot take: this is canonical AI education content, not a product announcement, and the real value is that it lowers the intimidation barrier around LLM internals.

–Strong evergreen tutorial: it teaches the architecture from first principles instead of hiding behind frameworks.
–High signal for engineers: the “from scratch” framing makes it useful as a conceptual map even if you never reimplement it exactly.
–The retweet is basically a distribution wrapper; the underlying asset is Karpathy’s free lecture, not the social post itself.
–If you’re scoring launchworthiness, this is more “influential tutorial/video” than “new product.”
