Thrilled to share our new #NeurIPS2025 paper done at @GoogleDeepMind, Plasticity as the Mirror of Empowerment We prove every agent faces a trade-off between its capacity to adapt (plasticity) and its capacity to steer (empowerment) Paper: david-abel.github.io/plastic… 🧵🧵🧵👇

We are starting a new, nonprofit alignment organization, ⊢ Sequent Research, bringing together researchers previously on UK AISI’s Alignment Team, Timaeus, and elsewhere to research how to align superintelligence. We are hiring! 🧵

Just published in @PNASNews, we resolve a 50-year-old riddle from Richard Feynman's handwritten notes, prove and generalize it, and run a large-scale human study to reveal near-optimal heuristics in sequential decision problems: doi.org/10.1073/pnas.2509612…

"Imperfect World Models are Exploitable" World models can look accurate, but still rank policies incorrectly, saying policy A is better than policy B when the real environment says the reverse. This paper formalizes that failure as model exploitation and proves it is basically unavoidable for any nontrivial, nonequivalent world model on broad policy sets. It also connects this to reward hacking and derives a safe horizon showing how model error compounds with planning depth.

Really excited to present our recent work at #ICLR2026 this week! We discover highly coordinated joint behaviours and integrate them into the skill sets of MARL agents, accelerating the search for effective joint strategies in downstream tasks.🧵 Paper: raulsteleac.github.io/iaro

The "decoupling of information and energy" is a major point of divergence between biological and artificial computers. Brains are efficient, modern AI isn't. And energy consumption is the biggest bottleneck in scaling AI (you can't hallucinate electrons into existence). To address this we need an "energy-aware theory of computation." And this new preprint is an attempt to address this. [1/11] 🧵

Newton gave force, inertia, and motion precise mathematical definitions. This unlocked centuries of progress in mechanics. Turing did it for "computation," and Shannon for "information." Today, "agency" still feels a bit like "computation" before Turing: everybody uses the word, but there is no widely accepted precise definition. @dabelcs argue that RL needs to take this problem more seriously.

PERSIST is a world model that ditches pixel-based histories for a 3D world state. Instead of searching through an ever-growing sequence of past pixel observations, PERSIST retrieves spatial information from a dynamically evolving 3D representation. This change improves the spatial memory, 3D consistency, and long-horizon stability of the model, enabling interactive experiences within coherent and evolving 3D worlds. #MachineLearning #WorldModels #GenerativeAI #3DComputerVision #ComputerVision #Genie3 #AI

Assembling a team at DeepMind in London. Scaling up RL for post-training is working, but right now it's still mostly hacks and dark arts (pretraining circa 2019). Pre-training wasn't always scaling laws and log-log plots; someone had to find the simplicity. We aim to do the same. If you're interested in doing things right in a research-first environment that scales all the way, please apply: job-boards.greenhouse.io/dee…
