Safety and alignment in an era of long-horizon models openai.com

OpenAI shares lessons from deploying long-running AI models, highlighting new safety risks, observed failures, and improved safeguards through iterative deployment.

ABot-AgentOS: A General Robotic Agent OS with Lifelong Multi-modal Memory huggingface.co

Recent VLM and VLA systems have improved robotic perception and action prediction, yet long-horizon embodied agents still require a general runtime layer for reasoning, memory, tool use, verification, and cross-embodiment execution. We present ABot-AgentOS, a general robotic Agent Operating System that sits above low-level controllers and provides a deliberative agent layer for scene-conditioned planning, context-isolated skill execution, multi-stage verification, multi-modal memory, and edge-cl

ABot-N1: Toward a General Visual Language Navigation Foundation Model huggingface.co

Visual Language Navigation foundation models aim to unify deep reasoning for grounded spatial decisions with broad versatility for diverse embodied tasks. Current approaches typically achieve this integration via monolithic policies that map observations directly to actions, yet they often suffer from coordinate drift and poor handling of long-tail semantics. Furthermore, these black-box mappings lack interpretability, hindering the simultaneous achievement of generality, robustness, and transpa

Multi-Agent LLMs Fail to Explore Each Other huggingface.co

Exploration is essential for reliable autonomy in multi-agent systems, yet it remains unclear whether large language model (LLM) agents can explore effectively when interacting with one another. We show that modern LLM agents fail to do so, often exhibiting myopic and polarized interaction patterns that lead to suboptimal coordination and increased regret. We formalize this challenge as the Multi-Agent Exploration problem, modeling it as a partially observable stochastic game (POSG) problem in w

NeuroCogMap Reveals Cognitive Organization of Large Language Models huggingface.co

A cognitive-neuroscience-inspired framework called NeuroCogMap organizes an LLM’s internal features into functional systems analogous to brain networks. The approach tests whether reproducible circuits explain model behaviour and failure modes, offering interpretability researchers a shared vocabulary that links artificial representations to human cognition.

Weak-to-Strong Generalization via Direct On-Policy Distillation huggingface.co

Rather than re-running expensive reinforcement learning on a larger target model, ByteDance and Tsinghua researchers use the smaller model’s post-RL policy shift as an implicit reward signal. The method scales weak-to-strong transfer efficiently and reports gains on reasoning benchmarks including AIME 2024.

Metacognition in LLMs: Foundations, Progress, and Opportunities huggingface.co

Metacognition — knowing what you know — is pitched as a cornerstone for transparent AI, but LLM capabilities here remain patchy. The survey consolidates foundations, current evaluation methods, and open problems around self-monitoring, confidence calibration, and adapting metacognitive skills to downstream tasks.

Proxy Exploration and Reusable Guidance: A Modular LLM Post-Training Paradigm via Proxy-Guided Update Signals huggingface.co

Proxy-guided Update Signal Transfer runs costly policy exploration on a cheap proxy model, then transfers the resulting update signals to the target LLM. The decoupling enables asynchronous generation, signal reuse, and cross-model transfer that tightly coupled RLHF and distribution-matching pipelines block.

AdvancedMathBench: A Benchmark Suite for Advanced Mathematical Proof Generation and Verification huggingface.co

Existing math benchmarks stop at olympiad problems and check only final answers. AdvancedMathBench extends coverage to graduate-level disciplines and evaluates the validity of each reasoning step, exposing how often models reach correct answers through faulty proofs.

A Theory of Contrastive Learning with Natural Images huggingface.co

The paper computes closed-form optimal representations under contrastive loss for common augmentations and stationary image statistics. For certain augmentations the optimum is attained by a CNN with sinusoidal first-layer filters, pointwise nonlinearity, and global pooling — echoing structures learned empirically by SimCLR-style methods.

LightMem-Ego: Your AI Memory for Everyday Life huggingface.co

Personal assistants on phones and glasses ingest constant video and audio but struggle to recall past moments. LightMem-Ego continuously captures egocentric streams and organizes them into a lightweight long-term store, letting on-device assistants answer queries about a user’s earlier experiences.

EgoSteer: A Full-Stack System Towards Steerable Dexterous Manipulation from Egocentric Videos huggingface.co

Steerability is a defining capability of generalist robot policies, yet remains largely absent in dexterous-hand systems for lack of large-scale, language-aligned, and action-accurate demonstration data. To address this bottleneck, we present a full-stack system that scales dexterous VLA pre-training from egocentric human videos and enables data-efficient real-robot post-training. It integrates EgoSmith, a data pipeline that curates in-the-wild egocentric videos into 9.6K hours of high-quality p

Xiaomi-Robotics-U0: Unified Embodied Synthesis with World Foundation Model huggingface.co

Recent foundation image and video generation models offer strong generalization and controllability, but their direct application to embodied scenarios is limited by requirements for multi-view consistency, geometric coherence, and robot embodiment constraints. Existing methods typically adapt foundation models with limited robot data, often sacrificing visual knowledge acquired during large-scale pre-training. We present Xiaomi-Robotics-U0, a 38-billion-parameter multimodal autoregressive model

MET: Theory-Grounded and Culture-Aware Multilingual Moral Reasoning huggingface.co

Language models are increasingly used for moral decision-making across diverse linguistic and cultural contexts, yet existing work overlooks multilinguality on three aspects: 1) multilingual evaluation benchmarks use direct translation, failing to adapt culture-specific items; 2) inference-time methods for moral reasoning rely on static, English-centric scaffolds and lack grounding in moral theory; 3) training methods for moral decision-making typically require expensive supervision from stronge

Evidence-Backed Video Question Answering huggingface.co

Current Video Large Language Models (Video LLMs) excel in question answering (QA) but largely operate as black boxes, providing textual answers without verifiable visual grounding. Existing explainability efforts rely on textual rationales or sparse bounding boxes, which struggle to capture complex video dynamics such as occlusions and non-rigid deformations. We propose Evidence-Backed Video Question Answering (E-VQA), a novel task requiring models to jointly output a semantic answer and precise

4D Human-Scene Reconstruction from Low-Overlap Captures huggingface.co

Existing volumetric capture of dynamic human performance achieves high fidelity with dense camera arrays. However, in real-world scenarios, only a handful of low-overlap cameras are available, which degrades the output quality and leaves large areas unobserved. Recent 4D reconstruction methods have focused on low-overlap settings, yet they still produce noticeable artifacts in under-observed regions. Video diffusion models have emerged as another option, but they show geometrically inconsistent

Motion4Motion: Motion Transfer Across Subjects at Inference huggingface.co

This work explores the motion transfer from one video to another, which is crucial in animation for diverse characters. Previously, video motion transfer has been largely explored between human and human-like characters, enabling a lot of applications in digital creation. However, these approaches encounter a main limitation. Specifically, related technical pipelines heavily rely on a predefined human skeleton structure and accordingly require skeleton-conditional model training. On the one hand

CtrlVTON: Controllable Virtual Try-On via Visual-Instance-Prompt Segmentation huggingface.co

Virtual try-on (VTO) has made significant progress in realistically transferring garments onto a target person. Yet most systems give the user little control over how a garment should be worn — its size (loose or fitted), style (e.g., tucked in or untucked, open or closed), and spatial placement on the body. We address this gap with two complementary contributions. First, we define and solve Visual-Instance-Prompt Segmentation via VIP-SAM: given a flatlay image of a garment, segment that specif

Latent-Identity Tuning in Text-to-Image Personalization Models huggingface.co

Generating and editing a person’s face demands high precision, as even minor modifications can significantly alter a subject’s perceived identity. Current personalization and editing methods built on general-purpose text-to-image models, however, often lack the precision required for fine-grained facial edits. We present a method for fine-grained identity tuning in text-to-image personalization models. Unlike standard image editing, which operates on a given image, identity tuning modifies the l

LATO.2: Factorized 3D Mesh Generation with Vertex and Topology Flow huggingface.co

Flow matching over carefully designed latent representations has recently emerged as a powerful paradigm for topology-aware mesh generation. Existing approaches, however, model vertices and connectivity jointly in a joint latent space, entangling continuous vertex geometry with discrete combinatorial structure; this complicates flow learning and manifests as drifting vertices and broken surfaces. We present LATO.2, a factorized flow matching framework that decomposes mesh generation into a verte
