🚨 New paper alert on discovery harnesses!
It turns out that the quality of sequential discovery depends on the quality of the initial population.
Fixing the compute budget, we show that parallel prompting could serve as a powerful initialization, raising the discovery floor!

Gemini 4 Argon taught a robot to play cornhole just by watching a video.
It mapped the physics, coded its own simulation, and taught @Apptronik's Apollo humanoid to sink 7 throws in a row.

🗣️ Can we evaluate the process of intellectual production rather than just the final text? Can we creatively design approaches to filter unaccountable research and nudge researchers and students toward genuine ownership of their work? Yes. 1/11 🧵

💥 The multiplication saga continues! It turns out, some frontier LLMs do struggle with simple multiplications.
Unlike GPT-6-Astra, Fable 5.1 with low reasoning has a blind spot where the accuracy of, say, 5x6 multiplications drops to ~0%!
The failure mode is very interesting: the 0% zone corresponds to a failure of adaptive thinking. The model decides that it shouldn't produce any reasoning and outputs the (wrong) answer directly. For larger multiplications, however, the model realizes it should produce a CoT first and then it gets the answer correctly. For very large multiplications (close to 20x20), the accuracy degrades again.
How many such simple blind spots do frontier LLMs still have? This is why slowing down and carefully studying generalization and safety is the top priority...

Had enough with chaotic mega AI conferences? A small high-quality conference becomes a rare gem. Glad to announce that the 4th CPAL cpal.cc is to be held in Tokyo, March 2027. This time not only we go to "see pals" but also the beautiful Japanese cherry blossom. Please join us!

We’re hiring! This is a rare opportunity to work with the folks that built Veo, Genie, and Gemini Omni — and advance the frontier of world models.

Introducing Flow Reasoning Models.
We developed a recurrent flow-based architecture to efficiently solve structured reasoning problems (e.g., Sudoku).
FRMs apply continuous flows to discrete data and recurrently refine their past mistakes through self-conditioning.

Simple ideas often generalize best! Loss smoothing is one of those really simple ideas that works surprisingly well for adaptation under distribution shift. Really excited about this line of work!
Our third invited talk by Sarath Chandar (@apsarathchandar) was about:

Second installment in my series on understanding RL algorithms, this time on Baselines or the power of subtracting zero.
Vanilla policy gradients have a serious issue: noise explodes on longer tasks. Double the episode length, and variance multiplies by eight 🧵

What if a foundation model could tell us how to modify its architecture to boost inference and reasoning instantaneously—without retraining? What if that tweak incurred near zero latency cost during generation and supported indefinite state tracking? arxiv.org/abs/2608.17981

I'm still looking for a postdoc to join my group at @ELLISInst_Tue and @MPI_IS! We offer very attractive working conditions (no teaching load, no bureaucracy, very competitive salary). Priority areas: scalable oversight, loss of control, RSI.
