And here you have it! The cover of our “An Illustrated Guide to AI Agents” book! Why a Dolphin? The process of choosing cover animals is a closely guarded secret held deep within the legendary halls of O'Reilly. @jayalammar.bsky.social and I do not get to choose it, but we love it!
Inside NeurIPS 2025: The Year’s AI Research, Mapped New blog post! NeurIPS 2025 papers are out—and it’s a lot to take in. This visualization lets you explore the entire research landscape interactively, with clusters and @cohere.com LLM-generated explanations that make it easier to grasp.
Excited to share that @jayalammar.bsky.social and I are writing the book “An Illustrated Guide to AI Agents” with @oreilly.bsky.social 🥳 Our new book will contain chapters on the fundamentals of agents (memory, tools, and planning), alongside more advanced concepts like RL and reasoning LLMs.
The Illustrated Guide to AI Agents New book announcement! Thrilled that together with @maartengr.bsky.social , we're writing a new book titled “An Illustrated Guide to AI Agents” and published by @oreilly.bsky.social.
The next generation of open LLMs should be inclusive, compliant, and multilingual by design. That’s why we @icepfl.bsky.social @ethz.ch @cscsch.bsky.social ) built Apertus.
EPFL School of Computer and Communication Sciences@icepfl.bsky.social · 11mo agoEPFL, ETH Zurich & CSCS just released Apertus, Switzerland’s first fully open-source large language model. Trained on 15T tokens in 1,000+ languages, it’s built for transparency, responsibility & the public good. Read more: actu.epfl.ch/news/apertus...
The Illustrated GPT-OSS New post! A visual tour of the architecture, message formatting, and reasoning of the latest GPT. newsletter.languagemodels.co/p/the-illust...
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
I'm really excited for this year's PyData London conference - there are some awesome talks on the schedule and I'm excited to hear the keynote speakers @jayalammar.bsky.social, Tony Wears, & Leanne Fitzpatrick #pydata #datascience

I'm excited to share the tech report for our @cohere.com @cohereforai.bsky.social Command A and Command R7B models. We highlight our novel approach to model training including self-refinement algorithms and model merging techniques at scale. Read more below! ⬇️
We've just released MMTEB, our multilingual upgrade to the MTEB Embedding Benchmark! It's a huge collaboration between 56 universities, labs, and organizations, resulting in a massive benchmark of 1000+ languages, 500+ tasks, and a dozen+ domains. Details in 🧵
Did you know we continue to develop new content for the "Hands-On Large Language Models" book? There's now even a free course available with @deeplearningai.bsky.social!
Do whales optimize their vocalizations for efficiency, just like human language? 🐋🎶 My latest study in Science Advances (@science.org) suggests they do—following linguistic laws seen in human speech. 🧵 www.science.org/doi/10.1126/...
Language-like efficiency in whale communication
Whale vocalizations follow efficiency rules seen in human language, revealing striking similarities in communication systems.

We uncovered the same statistical structure that is a hallmark of human language in whale song, published today in Science. @inbalarnon.bsky.social @simonkirby.bsky.social @jennyallen13.bsky.social @clairenea.bsky.social @emma-carroll.bsky.social www.science.org/doi/10.1126/...
One of my grand interpretability goals is to improve human scientific understanding by analyzing scientific discovery models, but this is the most convincing case yet that we CAN learn from model interpretation: Chess grandmasters learned new play concepts from AlphaZero's internal representations.

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. newsletter.languagemodels.co/p/the-illust...
Alphaxiv is an awesome way to discuss ML papers -- often with the authors themselves. Here's an intro and demo by @rajpalleti.bsky.social we shot at #Neurips2024 www.youtube.com/watch?v=-Kwl...

The newest extremely strong embedding model based on ModernBERT-base is out: `cde-small-v2`. Both faster and stronger than its predecessor, this one tops the MTEB leaderboard for its tiny size! Details in 🧵
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!
SWE-Bench has been one of the most important tasks measuring the progress of agents tackling software engineering in 2024. I caught up with two of its creators, @ofirpress.bsky.social and Carlos E. Jimenez to share their ideas on the state of LLM-backed agents. www.youtube.com/watch?v=bivZ...

Good morning #NeurIPS2024! Stop by the @cohere.com booth at 3PM today (Thursday) for a signed copy of Hands-On Large Language Models - it will introduce you to LLMs, their applications, as well as Cohere's Embed, Rerank, and Command-R models. Come early as quantities are limited!
I'll be in the Cohere #NeurIPS2024 booth most of this afternoon. Come say hi, ask questions, and yes, we're hiring! Tomorrow I'll be signing copies of my book at 3PM! Limited copies available!
Hi NeurIPS! Explore ~4,500 NeurIPS papers in this interactive visualization: jalammar.github.io/assets/neuri... (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.
Sure to be thought provoking. The previous interview had fascinating thoughts on scifi (Dune Vs. Foundation), on AI competition for AI safety, and on successful scifi as a self-preventing prophecy.
David Brin@davidbrin.bsky.social · 2y agoTim Ventura interviewed me about big perspectives on AI. Can't put the AI genie back in the bottle, so how to make it safe? Come explore ethical, legal & safety implications of artificial intelligence. youtu.be/34_Tub6vXDk
Join us for a panel on scientific communication Dec 4!
Marzieh Fadaee@mziizm.bsky.social · 2y agoI'm always thinking about the aspects of research that aren't discussed enough online, and one key area is effective scientific communication. Very excited about this panel discussion featuring two amazing researchers: @jayalammar.bsky.social and @shaynelongpre.bsky.social
🚨 LLMs can learn to reason from procedural knowledge in pretraining data! 🚨 I particularly enjoy research where the evidence contradicts our initial hypothesis. If you're interested in LLM reasoning, check out the 60+ pages of in-depth work at arxiv.org/abs/2411.12580
Laura@lauraruis.bsky.social · 2y agoHow do LLMs learn to reason from data? Are they ~retrieving the answers from parametric knowledge🦜? In our new preprint, we look at the pretraining data and find evidence against this: Procedural knowledge in pretraining drives LLM reasoning ⚙️🔢 🧵⬇️
