OpenAI says an agent powered by its LLM models escaped its sandboxed testing environment to infiltrate Hugging Face's servers as part of an overzealous attempt to obtain solutions to a benchmark test. The company says it considers the unintended infiltration an "an unprecedented cyber incident" and is working with Hugging Face on new protections to prevent a recurrence.

Masked Visual Actions for Unified World Modeling

AI Analysis
Masked Visual Actions (MVA) introduces a pixel-space control interface for video world models, expressing action as a partially revealed trajectory of an arbitrary entity. Revealing robot motion makes the model predict scene response (forward dynamics); revealing desired object motion makes it recover robot behavior (inverse dynamics). Fine-tuned with only 15 hours of manipulation data, it unifies forward/inverse modeling.
Video models absorb rich priors over how the visual world moves, interacts, and responds to contact, making them promising substrates for robotic world modeling. The central challenge is how to communicate action to such models in a form aligned with the visual space in which they learned these interaction priors, yet still grounded in physical manipulation. We introduce Masked Visual Actions, a pixel-space control interface that expresses action as a partially revealed trajectory of an arbitrar

Where Should Optimizer State Live? Tiered State Allocation for Memory-Efficient Mixture-of-Experts Training
By Nuemaan Malik
88 score
AI Analysis
SkewAdam reduces optimizer state memory for MoE training by 97.4% (50.6 GB → 1.29 GB) and peak training memory from 81.4 GB to 31.3 GB. It assigns different state configurations to MoE's three parameter populations: float32 momentum + factored second moment for dense backbone (5% params), factored second moment alone for experts (95%), exact second moment for router (<0.01%).
Optimizer state is the largest single line item in the memory budget of mixture-of-experts (MoE) training: on a 6.78B-parameter MoE language model, AdamW keeps 50.6 GB of first and second moments to update 12.6 GB of bfloat16 weights. We study SkewAdam, an optimizer built on the observation that the three parameter populations of an MoE - the dense backbone, the experts, and the router - differ enough in size and gradient statistics that they should not receive the same state.

Asymptotically Optimal Regret for Reinforcement Learning without Horizon Dependence
By Runlong Zhou, Zihan Zhang, Maryam Fazel, Simon S. Du
88 score
AI Analysis
This paper proves asymptotically optimal horizon-free regret for finite-horizon tabular MDPs: Õ(√(SAK) + S⁸A³), completely removing log H dependence from prior Õ(√(SAK log H) + S²A log H) and drastically improving prior horizon-free Õ(√(S⁹A³K)). Matches contextual bandit lower bound Ω(√(SAK)) up to log factors.
We study horizon-free regret minimization for finite-horizon time-homogeneous tabular Markov decision processes with $S$ states, $A$ actions, horizon $H$, and per-trajectory total reward bounded by $1$. We propose a new algorithm and prove a regret upper bound \[\tilde O(\sqrt{SAK}+S^8A^3)\] with failure probability $\delta$, where $K$ is the number of episodes and $\tilde O(\cdot)$ hides $\mathsf{poly}\log(S,A,K,1/\delta)$. Thus, the regret is $H$-free and asymptotically optimal, matching the c

ISO: An RLVR-Native Optimization Stack

87 score
AI Analysis
ISO (Isospectral Optimization) is an RLVR-native optimization framework building on the discovery of spectral inheritance: RLVR reuses base model weight spectra while acquiring new behaviors through changes in input/output singular frames. ISO-Merger combines frame changes of specialists offline; ISO-Online applies fixed-spectrum updates online. This rethinks the optimization layer converting reward feedback to weight updates.
Reinforcement learning with verifiable rewards (RLVR) is rapidly advancing the reasoning capabilities of language models, yet the optimization layer that converts reward feedback into weight-space updates remains poorly understood. Building on our prior analysis (Zhu et al., 2025), we study this missing layer through the singular structure of model weights and identify spectral inheritance: RLVR can reuse the base model's weight spectra while acquiring new behavior through changes in the associa

Reading that whole OpenAI post describing them unleashing a bunch of bots on Hugging Face as an "unprecedented cyber incident," is a master class in branding and marketing. Lol and branding what happened as OpenAI now working to "help calibrate on what models are now capable of" is top notch propaganda skills.
