The most recent is this, which I believe was made after he left Tesla: https://github.com/karpathy/nanoGPT And it's accompanying video series: https://karpathy.ai/zero-to-hero.html Another example (although I honestly don't remember if he made this one between jobs) is: https://github.com/karpathy/micrograd

  11. Nobody writes code in terms of Nands but there is Nand to Tetris course ("The Elements of Computing Systems: Building a Modern Computer from First Principles" book) https://www.nand2tetris.org pytorch to LLMs has a lot to show even without Python to pytorch part.

  15. This doesn't even seem to look at "predictions" if you dig into what it actually did. Looking at my own example (#210 on https://karpathy.ai/hncapsule/hall-of-fame.html with 4 comments), very little of what I said could be construed as "predictions" at all. I got an A for commenting on DF saying that I had not personally seen save corruption and listing weird bugs. It's true that weird bugs have long been a defining…

  21. > https://karpathy.ai/hncapsule/2015-12-24/index.html#article-... I wonder why ChatGPT refused to analyze it? The HN article was "Brazil declares emergency after 2,400 babies are born with brain damage" but the page says "No analysis available".

  23. It somehow feels right to see what GPT-5 thinks of the article titled "Machine learning works spectacularly well, but mathematicians aren’t sure why" and its discussion: https://karpathy.ai/hncapsule/2015-12-04/index.html#article-...

  25. Examples: tptacek gets an 'A' for his comment on DF which the LLM claiming that the user "captured DF's unforgiving nature, where 'can't do x or it crashes is just another feature to learn' which remained true until it was fixed on ..." Link to LLM review: https://karpathy.ai/hncapsule/2015-12-02/index.html#article-... . So the LLM is praising a comment as describing DF as unforgiving (a characterization of the pres…

  27. Are you sure? The third section of each review lists the “Most prescient” and “Most wrong” comments. That sounds exactly like what you're looking for. For example, on the "Kickstarter is Debt" article, here is the LLM's analysis of the most prescient comment. The analysis seems accurate and helpful to me. https://karpathy.ai/hncapsule/2015-12-03/index.html#article-... phire > “Oculus might end up being the most succ…

  29. This is a perfect example of the power and problems with LLMs. I took the narcissistic approach of searching for myself. Here's a grade of one of my comments[1]: >slg: B- (accurate characterization of PH’s “networking & facade” feel, but implicitly underestimates how long that model can persist) And here's the actual comment I made[2]: >And maybe it is the cynical contrarian in me, but I think the "real world" aspec…
