The first batch of tickets will be released TODAY (Aug 10) at 1pm PT (pacific time). We are fairly certain we will be able to release more later on, so if tickets run out, we will direct people to a wait list (sign up if interested) colm.eventhosts.cc/register

We are delaying general registration to Aug 10 to carefully manage author registration and make sure that all authors (main + workshops) get to register. We appreciate the patience

I leave this project with a lot of food for thought about how we get to compact (and equally capable) models

Very excited about @nthngdy.bsky.social's new work! It really gets to the bottom (or top, depends where the head in LMs is 😜) and fundamentals of contemporary LLMs. A real treat of a paper: solid theory, and very cool experiments.

Hence, this is an interesting and important benchmark. Through a simple environment, it exposes a fairly fundamental flaw in current models

Yoav Artzi @yoavartzi.com · 29/12/2025
This is not surprising, and aligns with other findings in the literature regarding visual reasoning and manipulation

Yoav Artzi @yoavartzi.com · 29/12/2025
The prompts do provide rudimentary illustration. The stateful version allows the model to see the outcome of its own actions, technically allowing it to infer the physics. Generally though, the result for LLMs out of the box is negative.

Yoav Artzi @yoavartzi.com · 29/12/2025
Most of the experiments are not with VLMs, but with a diverse set of RL methods. Do LLMs understand physics? They definitely generate outputs that seem to indicate so.

Zoe presented this paper at NeurIPS D+B: it's all knots(🪢🪢🪢!?), no language tokens were harmed (or reinforced) in the process It's such a fun and creative paper, a real mind twist ;) You really get to think carefully about visual intelligence looking at these knots 🪢

This is maybe counterintuitive to the original intention of just index the chaos to make it accessible. I guess that ideal of search softened a long time ago
000
Yoav Artzi @yoavartzi.com · 10/11/2025
That's definitely part of it, because this digestions has deeper history. Search engine indexing also seems just easier, so companies opt to it, even pre AI-overview-everything

Yoav Artzi @yoavartzi.com · 10/11/2025
Re peer-rev --> pre-print servers: arXiv is a simple uniform place to store. Indexing engines love it, so if you want something to be searchable, nothing is better. To make things worse, at times it seems like journals/proceedings almost play a game of hide-and-seek with PDFs

This kind of ad-hoc adaptation is hard in general of LLMs, but you can post-train to it for some degree arxiv.org/abs/2508.06482 I suspect contemporary ASR models have the same backbone, so maybe applicable too More broadly, there is a lot of interesting stuff to do in this space of adaptation

Humans communicate with increasing efficiency in multi-turn interactions, by adapting their language and forming ad-hoc conventions. In contrast, prior work shows that LLMs do not naturally show this ...

I am potentially recruiting a postdoctoral fellow through this program. If interested, name me as a mentor, and ping me to let me know that you are applying! The process includes some sort of interview, so I can try to squeeze a few of these in advance (it will help a lot!)

There's the legit gaming, which is just optimizing for the metrics and breaking them. Then there's the really fake stuff, like citation rings. You would thing citation translate to bitcoins with the level of creativity and effort that people put into it

It's pretty crazy how the entire citation game has been manipulated. It's enough to give a quick look at Semantic Scholar for Bengio, who GScholar just gave 1M citations. SScholar gave 0.5M, but it's not only the number, it's the top citers

It definitely doesn't seem to hold in process, which lacks any similar regulation or structure. The (sci-fi-ish?) argument is that one cannot disentangle deployment/impact from development (i.e., one cannot shut it down).
000
Yoav Artzi @yoavartzi.com · 23/10/2025
The analogy sounds great, but are you sure it really holds? Public buy-in aside. Development vs. deployment is clearly distinguished in vaccines, both in being built into the process and in delaying impact to deployment. Does the same hold for so-pronounced ASI development?
