"It is easy to understand why so many of us are fond of birds. They are lively; they are lovely; and they are everywhere." Opening sentences to "The life of birds", by David Attenborough. Such a memorable opening!

Interested in doing a PhD in machine learning or computer vision at the University of Edinburgh? My group works on topics related to: * Autonomous Scientific Discovery * Human-in-the-Loop Machine Learning * 3D Vision and Robotics * AI for Ecology and Conservation

Super excited to share that our method to convert language models to byte-level has been published in @nature.com! This was originally the approach behind Bolmo. We now generalized it to other model families. All checkpoints (including new Qwen and Llama models) and data are public!

A group of 25 Fields Medalists, including myself, have made a joint declaration on Math and AI: mathandai.org . We welcome additional signatories. See also this article in the Economist announcing the declaration: www.economist.com/science-and-...

Developing LLMs to be Large Plagiarism Machines is a choice "we cannot rule out that de-identified data derived from your usage of our products helped improve our models"

The first call for NeurIPS Paris 2026 volunteers is open! We are seeking for PhD students and postdocs to assit during the conference in exchange for complimentary registration. Application form: forms.gle/HGDUzS7y7yvq... 1st call deadline: September 10th

Me, reading some badly written one-shotted AI "preprint" claiming to solve an open problem in the least interesting way possible

I've been unsettled lately when reading messages and papers. It feels like I'm dissociating. Everything seems a bit alien, even if it's completely human. I've had a realization: When our simulations finally exited the Uncanny Valley, they brought the Uncanny with them.

Fantastic postdoc position! 👀

Today NeurIPS is announcing our official satellite event in Paris. After responding to the call from Ellis following the success of EurIPS in December, we are pleased to reach a new milestone by joining forces with the NeurIPS organizing committee for the 2026 edition.

@kaggle.com seriously? Are you really hosting an "object recognition" challenge with classes which include "plane,drone,human,ship" and goals which include "identifying objects of interest in operational contexts"?

We are advertising a postdoc position to work on #generative #models, #structure #induction, and MI #estimation with Michael Gutmann as part of @genaihub.bsky.social ! elxw.fa.em3.oraclecloud.com/hcmUI/Candid... Get in touch! (#ML #AI) 👉 homepages.inf.ed.ac.uk/snaraya3/ 👉 michaelgutmann.github.io

🧵New paper: "Lost in Backpropagation: The LM Head is a Gradient Bottleneck" The output layer of LLMs destroys 95-99% of your training signal during backpropagation, and this significantly slows down pretraining 👇

In light of the current funding situation (worldwide), a modest proposal: instead of pouring billions of dollars into GenAI claiming "it *could* accelerate science and research," consider putting 1% of that amount in what *will* accelerate science and research. Namely, funding science and research.

We will be running the 13th iteration of the workshop on Fine-Grained Visual Categorization (FGVC) at CVPR this summer. We have an open call for papers that explore questions in visual recognition. Please see our website for more information: sites.google.com/view/fgvc13/...

Fantastic opportunity to work on #reliable #LLMs in Edinburgh! Antonio is phenomenal and super fun to work with!

Yeah? Well, you know, that's just like your slopinion, man. (2025 version)

Introducing Bolmo, a new family of byte-level language models built by "byteifying" our open Olmo 3—and to our knowledge, the first fully open byte-level LM to match or surpass SOTA subword models across a wide range of tasks. 🧵
