Releasing the Energy-Book 🔋 from its first appendix's chapter, where I explain how I create my figures. 🎨 Feel free to report errors via the issues' tracker, contribute to the exercises, and show me what you can draw, via the discussion section. 🥳 github.com/Atcold/Energy-…

I landed (by accident) on @OpenRead_HQ. I tried the UI and found a bug. I emailed them about it and… Within *30 minutes* they fixed the interface!!! 😳 This responsiveness alone got me to tweet this episode. Now I'm actually interested in giving it a try for real. 🔥🔥🔥


Gregory does it again! 🥳🥳🥳 His blog posts are phenomenal. So, it’s no surprise @syhw likes his latest publication! 🔥🔥🔥

This is an excellent history of LLMs, doesn't miss seminal papers I know. Reminds you we're standing on the shoulders of giants, and giants are still being born today. gregorygundersen.com/blog/2025/10/0…

Soon we'll have RottenTomatoes for research papers.

It only took 13 years, but dark mode is finally here sebastianraschka.com/blog/2021/dl-c…

Tagging the missing author, @ezyang, as usual. Academic Twitter, you can do better at citations.

6 years later, still the best introduction to pytorch internals.

How do we evaluate LLMs? I wrote up a new article on (1) multiple-choice benchmarks, (2) verifiers, (3) leaderboards, and (4) LLM judges All with from-scratch code examples, of course!

Excited to share Equilibrium Matching (EqM)! EqM simplifies and outperforms flow matching, enabling strong generative performance of FID 1.96 on ImageNet 256x256. EqM learns a single static EBM landscape for generation, enabling a simple gradient-based generation procedure.

I quite enjoyed this and it covers a bunch of topics without good introductory resources! 1. A bunch of GPU hardware details in one place (warp schedulers, shared memory, etc.) 2. A breakdown/walkthrough of reading PTX and SASS. 3. Some details/walkthroughs of a number of other…

The directional derivative of a scalar field ℒ:ℝᴺ → ℝ at w⁰ along direction û is given by: Dᵤℒ(w⁰) = ∇ℒ(w⁰)ᵀ û = ‖∇ℒ(w⁰)‖ cos ϕ, where ϕ is the angle between ∇ℒ(w⁰) and û. The direction of maximum decrease has û pointing towards −∇ℒ(w⁰).

I haven’t expressed myself on politics for a while, but… First the irregulars were removed ⇒ no field or construction workers. Now the regulars have to pay $100k/year to work ⇒ mass migration? Is this an active sabotage plan for the country I’ve become to call home? 💔💔💔


Me: finishes a “successful” lecture. Student question: we have to do xyz if A and B are equal. (A and B are integers.) What if A is “almost” B? Me: 🥹🥹🥹 Conclusion: numerical examples are actually NECESSARY. 🥹🥹🥹
