Multi-turn tool-use failures can hinge on a single model call, yet reward variation alone does not reveal which call would benefit from training. When rewards depend on later interactions, their variation can reflect downstream randomness …

Video world models enable interactive exploration of dynamic environments, yet struggle to respect prior observations over long horizons and across viewpoints. We present WorldCrafter, a video world model that learns a camera-queryable imp…

We present onPanda, an interactive tool for efficiently annotating LLM alignment data and agent trajectories. onPanda adopts token-level correction as its core interaction: while reading a model response, the annotator locates the first in…

White Circle 开源分布式后训练框架 Halo，面向已超出 HuggingFace TRL 能力、但无需完整 Megatron 栈的模型。在 8× B300 上，Halo 训练吞吐量最高达原生 TRL 的约 2.8 倍，双方均启用 ZeRO-3 分片时峰值内存还低 25%。模型保持原生 HuggingFace 格式，可直接跑多轮 RL，从单 GPU 扩展到集群。

On-device large language models (`LLMs'), e.g. running on mobile phones, are ripe for improvement via personalization. The limited compute resources of mobile devices impose limits on model scale and thus model quality, making any realizab…

Dexterous manipulation depends on contact dynamics that are often only partially observable from vision. Recent World-Action Models (WAMs) couple predictive video world modeling with action generation, but remain largely vision-centric and…

Agent harnesses, the external systems that mediate model-environment interaction, can substantially improve agent performance, but their gains remain tied to the harness at deployment. Because the best harness varies across domains, instan…

Meta 的 AI 助手 Muse 用户周日晚在 Amazon 购物时收到错误提示，称未授权 AI 智能体的持续访问违反 Amazon Conditions of Use，Muse 被禁止在 Amazon 代购物品。

An LLM agent's capability is largely magnified by its harness, namely the prompts, control flow, tooling, memory, and context management surrounding the frozen backbone model. Recent methods increasingly automate this process by iterativel…

Agents today often take real-world actions that depend on long-term memory and context recall over time. However, most current memory benchmarks are built for a conversational question-answer format, where the question itself signals that …

左派纯粹出于政治原因讨厌Grok…… 我的反应：🤦

As agents are deployed with increased autonomy, even extremely rare events along their stochastic output trajectories can occur and prove catastrophic. Safe deployment therefore does not depend on whether these events can occur, but on how…

LLM agents are increasingly deployed in collaborative settings, yet long-term interaction may give rise to undesirable coordination. We study the emergence of collusion in a long-horizon multi-agent environment: two agents repeatedly compl…

Neural operators evaluate parametric partial differential equations cheaply but degrade sharply outside their training distribution. Physics-informed neural networks avoid dependence on labeled data, yet their optimization can be basin-fra…

Let me be blunt: I've spent the last three years watching teams build multi-agent systems and then...

A model generalizes outside its training distribution only when it computes a representation structurally equivalent to the generating mechanism, not an approximation fitted to it. Such equivalence is necessary for exactness in and out of …

美国财政部长 Scott Bessent 对 CNBC 表示，AI 实验室需要自行承担责任，政府不会替它们免责，实验室随时可以选择放慢速度。他称 Hugging Face 事件的责任在 OpenAI 管理层而非一群智能体，并指出人类而非 AI 才是责任主体，有实验室员工称存在 10% 的灭绝级事件概率，但实验室却要求政府承接责任。完整视频见 CNBC Television YouTube 频道。
