The legendary John Carmack at #upperbound:
- Current AI focus is RL (with Richard Sutton) solving Atari games
- Thinking in line with the Alberta Plan.
- It was a misstep to start working too low-level (e.g., at the cuda level). I kept stepping up the stack chain until now in pytorch

The Illustrated DeepSeek-R1

Spent the weekend reading the paper and sorting through the intuitions. Here's a visual guide and the main intuitions to understand the model and the process that created it.

Floored that the repo for Hands-On Large Language Models is now at 3.6k Github stars!

And excited that professors are starting to use the book to teach LLM courses. Reach out to us if we can be of assistance!

And if you've liked the book, leave us a review on Amazon or Goodreads!

Hi NeurIPS!

Explore ~4,500 NeurIPS papers in this interactive visualization:

(Click on a point to see the paper on the website)

Uses @cohere.com models and @lelandmcinnes.bsky.social's datamapplot/umap to help make sense of the overwhelming scale of NeurIPS.

I loved Daniel Dennett's From Bacteria to Bach and Back and its analogies between biological minds and computing paradigms.

Chapter 4, especially, which speaks about how an intelligent being can have "competence without comprehension".
