The inherent complexity of video understanding makes it difficult to determine whether Video-LLM benchmark performance stems from visual perception, linguistic reasoning, or knowledge priors. While many benchmarks have emerged to assess high-level reasoning, shared criteria for evaluating video understanding remain largely overlooked. Instead of introducing yet another benchmark, we take a step back to re-examine the criteria for evaluating video understanding. In this work, we introduce Video-Oasis, a sustainable diagnostic suite for systematically auditing existing video understanding benchmarks. This audit reveals that 55\% of existing benchmark samples are solvable without visual input or temporal context. After filtering these shortcuts, the remaining video-native challenges expose a substantial capability gap: state-of-the-art models perform only marginally above random guessing. Building on these findings, we use the distilled challenges as a testbed to investigate which algorithmic design choices contribute to robust video understanding. We hope our work provides a practical foundation for constructing rigorous video benchmarks and evaluating future Video-LLMs. Code is available at https://github.com/sejong-rcv/Video-Oasis.

Zero-Shot Compositional Action Recognition (ZS-CAR) requires recognizing novel verb-object combinations composed of previously observed primitives. In this work, we tackle a key failure mode: models predict verbs via object-driven shortcuts (i.e., relying on the labeled object class) rather than temporal evidence. We argue that sparse compositional supervision and verb-object learning asymmetry can promote object-driven shortcut learning. Our analysis with proposed diagnostic metrics shows that existing methods overfit to training co-occurrence patterns and underuse temporal verb cues, resulting in weak generalization to unseen compositions. To address object-driven shortcuts, we propose Robust COmpositional REpresentations (RCORE) with two components. Co-occurrence Prior Regularization (CPR) adds explicit supervision for unseen compositions and regularizes the model against frequent co-occurrence priors by treating them as hard negatives. Temporal Order Regularization for Composition (TORC) enforces temporal-order sensitivity to learn temporally grounded verb representations. Across Sth-com and EK100-com, RCORE reduces shortcut diagnostics and consequently improves compositional generalization.

Scientific ideas rarely start from a blank page. They inherit mechanisms, repair known limitations, and recombine pieces of earlier work, much like biological genomes. Current benchmarks still say little about whether AI systems can follow this inheritance structure. We present IdeaGene-Bench (IG-Bench), a benchmark for scientific lineage reasoning and lineage-grounded idea generation. IG-Bench is organized around the IdeaGene framework: each paper or proposal is represented as a set of minimal, typed, evidence-grounded Idea Genome objects, and a GenomeDiff aligns these objects to record inheritance, mutation, loss, external import, and novel insertion under six operational evolutionary dynamics. The benchmark contains 1,961 golden lineage traces, 1,085 curated Idea Genome objects, and 920 pairwise GenomeDiff records across 10 scientific domains. It supports two evaluations. IG-Exam (42 task types, 1,029 instances) tests closed-form lineage reasoning across Idea Genome abstraction, inheritance tracing, evolutionary reasoning, and lineage verification. IG-Arena evaluates generation with a lineage-conditioned Population-Evolution Score(PES), asking whether a proposal can be inserted as a coherent descendant of a given lineage population: it should inherit the right Idea Genome objects, vary meaningfully from nearby work, and offer selection value for future research. Experiments on 14 LLM-based scientists expose a compositional bottleneck. The strongest system reaches only 27.3% exact accuracy on lineage reasoning, and structured lineage context reshuffles system rankings rather than helping every participant uniformly.

Recovering high-quality video from sparse event streams is a challenging task. Regression methods often blur textures, while existing generative models struggle with long-term stability. We propose LongE2V, a novel approach that leverages pre-trained video diffusion priors to jointly handle event-based video reconstruction, prediction, and frame interpolation. By fine-tuning a foundational video model, our approach achieves high data efficiency and superior perceptual quality. We introduce Autoregressive Unrolling and Adaptive Context Switching to mitigate temporal drift in extremely long sequences. We also propose Reencoding Alignment with Cross Residual Correction to ensure precise bidirectional consistency during frame interpolation. Furthermore, Event Voxel Density Augmentation ensures robustness across varying sensor resolutions. Extensive experiments on real-world benchmarks demonstrate that LongE2V outperforms state-of-the-art methods across all three tasks, exhibiting exceptional temporal coherence and zero-shot generalization.

The rapid development of large language models and multimodal large language models has accelerated the emergence of proactive agents capable of operating everyday tools and assisting users in real-world environments. However, existing benchmarks struggle to evaluate such agents effectively, as they often rely on sandboxed environments and single-turn evaluation paradigms. Moreover, their scenario-based task taxonomies mix multiple model capabilities within the same task category, making it difficult to identify the root causes of agent failures. To address these limitations, we introduce UniClawBench, the first capability-driven benchmark designed to evaluate proactive agents in dynamic, real-world settings. UniClawBench is built around five foundational model capabilities: Skill Usage, Exploration, Long-Context Reasoning, Multimodal Understanding, and Cross-Platform Coordination. Based on these capabilities, we design 400 bilingual real-world tasks. Unlike previous benchmarks that rely on static, pre-recorded answers, our benchmark evaluates agents in live Docker containers using fine-grained, step-by-step completion checkpoints. Furthermore, we design a closed-loop evaluation strategy comprising an executor agent, a hidden supervisor agent, and a user agent to simulate realistic multi-turn human feedback without leaking grading criteria. To disentangle base model capabilities from framework-level design choices, we evaluate state-of-the-art models under multiple agent frameworks. Through comprehensive comparisons across both models and frameworks, we show how base model capabilities and agent framework designs jointly shape performance in real-world environments. To facilitate future research, we make our benchmark and code publicly available at https://github.com/HKU-MMLab/UniClawBench.

In this work, we present Canvas360, a two-stage framework for in-context panoramic generation that combines geometry-aware pretraining with downstream task-specific fine-tuning. To address the lack of large-scale, high-quality training data tailored to in-context panoramic tasks, we propose Canvas360Dataset, a collection of 1M high-quality paired panoramic samples for style transfer, inpainting, outpainting, and editing, enabling effective supervision across diverse in-context generation scenarios. On the modeling side, Canvas360 enhances text-to-panorama generation through parallel depth generation, velocity circular padding, and similarity loss regularization, enabling the model to learn geometry-aware representations, capture object distortion details, and improve geometric consistency and global coherence. Furthermore, empowered by strong panoramic priors, Canvas360 enables a unified in-context panoramic generation framework that supports diverse downstream tasks via token-level concatenation, surpassing prior methods in both task coverage and modeling flexibility. Extensive experiments show that Canvas360 improves panoramic image fidelity, achieving particularly strong performance on the panorama-specific FAED metric and competitive or leading results across the reported quantitative evaluations. More information can be found on our project page: https://zry000.github.io/Canvas360/

Current computational approaches for drug design typically focus on generating molecules conditioned on specific targets or general molecular properties, often neglecting the influence of disease context on target behavior and therapeutic outcomes. To address this gap, we introduce DrugGen-2, a novel generative model that designs small molecules conditioned on both disease ontology and target protein sequences. DrugGen-2 was developed by fine-tuning a pre-trained GPT-2 model on a curated dataset of approved drugs linked to their diseases and targets, using a two-step strategy of supervised fine-tuning followed by reinforcement learning via group relative policy optimization (GRPO). This process was guided by reward functions optimizing for chemical validity, novelty, diversity, and high predicted binding affinity. When evaluated on five protein targets relevant to diabetic nephropathy, DrugGen-2 significantly outperformed baseline models (DrugGPT and DrugGen). It demonstrated a superior capacity to generate unique molecules, exhibited greater structural similarity to approved drugs, and achieved improved predicted binding affinities across all targets. Molecular docking analyses further supported these findings, identifying candidate ligands with strong binding potential, including compounds with predicted affinities (-9.917, -9.485, and -9.367) exceeding those of reference drugs such as enalapril for angiotensin-converting enzyme (-8.283). By integrating disease-specific context into molecular generation, DrugGen-2 advances AI-assisted drug discovery, offering a powerful tool for de novo design and drug repurposing that accounts for the complex interplay between diseases and molecular targets.

Modern LLMs are increasingly deployed in long-context applications such as retrieval-augmented generation, repository-level coding, and agentic workflows whose accumulated reasoning and tool traces routinely push the input an order of magnitude past the pretraining window, making zero-shot context extension the dominant deployment path for open-weight checkpoints. Most existing zero-shot methods fix a single rescaling factor up front, so an aggressive factor sacrifices short-context fidelity while a conservative one breaks down at long contexts. We propose Jet-Long, a tuning-free zero-shot method that pairs a local RoPE-faithful window with a long-range window whose rescaling factor adapts dynamically to the current sequence length, recovering the base model exactly at short inputs while extrapolating cleanly at long ones. An inclusion-exclusion attention merge and an on-the-fly RoPE correction rotation make the bifocal construction essentially free at inference; fused into a single CuTe kernel, long-context prefill reaches up to 1.39times FA2 throughput on H100 (approaching the Hopper-only FA4), and single-batch generation incurs le 4% overhead at every length. On Qwen3-1.7B/4B/8B up to 128K context, Jet-Long leads RULER by +4.79/+2.18/+2.03~pp over the strongest baseline at 1.7B/4B/8B, achieves the best overall accuracy on HELMET-RAG (a benchmark identified by HELMET as the most efficient predictor of downstream long-context performance) and attains the lowest PG-19 perplexity. Jet-Long also generalizes to hybrid attention architectures such as Jet-Nemotron for further long-context improvement without retraining, and remains hyperparameter-resilient for ease of deployment.

Reasoning has become a core capability for large models, especially when reliable decisions require understanding logical consequences. Recent video generation models offer a reasoning path distinct from previous Chain-of-Thought (CoT): reasoning can unfold through temporally connected frames, known as Chain-of-Frame (CoF) reasoning. However, existing video generators are primarily trained on general video corpora, still lacking diverse supervision and dedicated designs for CoF reasoning. To address this gap, we introduce OpenCoF, a framework comprising the OpenCoF-17K dataset, a reasoning video dataset spanning 11 task families, and Wan-CoF, a fine-tuned video model for studying whether diverse temporal supervision improves CoF behavior. Across four video reasoning benchmarks, Wan-CoF achieves considerable gains over the Wan2.2-I2V-A14B baseline. Building on this, we empirically explore more advanced designs for CoF capabilities, i.e., equipping the model with visual and textual reasoning tokens. This mechanism respectively captures low-level visual cues and high-level semantic priors for spatial and temporal reasoning. Through performance comparisons and attention analysis, we examine how these tokens contribute across model depth, denoising steps, space, and time. Our results suggest that stronger video reasoning requires both broad temporal supervision and explicit mechanisms for organizing intermediate reasoning state. We open-source the dataset, model, and code to facilitate future research on reasoning-oriented video generation.

The growing demand for image-to-video creation on mobile devices has increasingly focused on cinematic motion effects like bullet time, dolly zoom, slow motion, etc. While Diffusion Transformers (DiTs) exhibit strong performance in video generation, their large parameter sizes and multi-step iterative denoising processes lead to substantial computational overhead, making efficient generation on mobile devices challenging. We propose CineMobile to bridge the gap. In particular, CineMobile adopts a three-fold optimization strategy: (1) leveraging a distillation-guided pruning approach to derive a compact yet efficient model that retains the essential video generation capabilities required for cinematic effects; (2) optimizing the compressed model into a 4-step generator via a combination of diffusion distillation and reinforcement learning; (3) employing a hybrid post-training quantization strategy to compress the model footprint to under 1 GB. Experimental results show that compared to the teacher model with the Wan 2.1 architecture, CineMobile achieves a 40x speedup in generation while maintaining comparable visual quality. Specifically, CineMobile generates 49-frame 480p videos with a per-step denoising latency of 0.6s on an NVIDIA H200 GPU and 20s on the MediaTek Dimensity 8400 Ultimate 5G platform, with a peak memory usage of 1.8 GB, demonstrating its practical applicability for mobile-based image-to-video creation.

Self-attention lets each token retrieve information from the full context, but its quadratic cost in sequence length limits training and inference at long context. This paper presents a comparative study of softmax attention and four recent recurrent linear-attention architectures: DeltaNet, Gated DeltaNet, Kimi Delta Attention, and Gated DeltaNet-2. We express these mechanisms in a common recurrent-memory notation, making explicit how they differ in expressivity, memory decay, erase and write control, training throughput, and implementation complexity. Our experiments center on 350M-parameter models trained for 15B tokens, and include optimizer and learning-rate comparisons, hybrid-versus-pure stack comparisons, sequence-length runtime measurements, larger DeltaNet runs at 1.3B and 3B parameters, and a small set of downstream evaluations. The reported speed results measure training throughput and iteration time; we do not provide an empirical inference-speed benchmark. Within the reported 350M-parameter, 15B-token sweep, Kimi Delta Attention with Muon reaches the lowest final validation loss, a pure Gated DeltaNet stack trained with AdamW has the highest normalized training throughput, hybrid stacks generally improve loss at a throughput cost, and Muon consistently lowers final validation loss relative to AdamW in the matched architecture settings we evaluate. We introduce and evaluate lightweight cross-layer routing mechanisms for DeltaNet-style memories. The most natural DeltaNet-inspired formulation, forwarding a lower layer's delta-rule write error into the next layer's value target, does not improve over matched baselines. Routing into the aligned hidden stream and forwarding the write value instead yields a modest improvement in the matched runs we report: Cross-Layer Value Routing (CLVR) lowers final validation loss for both DeltaNet and Gated DeltaNet.

In long-horizon tasks, decision-relevant state is often scattered across an expanding trajectory, while the action agent must surface it and act. As trajectories grow, task requirements, environment facts, prior attempts, diagnoses, and open subgoals can be buried in the context window or pushed beyond it, failing to influence decisions when needed. We call this failure mode "behavioral state decay". We study memory as an active intervention mechanism rather than passive retrieval. A separate memory agent runs alongside an unmodified action agent, updating a structured memory bank from the recent trajectory and deciding whether to inject a memory-grounded reminder or remain silent. The module is plug-and-play with frontier action agents and existing agent harnesses. Across Terminal-Bench 2.0 and τ^2-Bench, it improves pass@1 for both weaker and stronger action agents, with gains of +8.3 pp on Terminal-Bench and +6.8 pp on τ^2-Bench. Ablations show that selective intervention outperforms passive bank exposure, always-on injection, advisor-only guidance, and general retrieval. As an early step toward open-weight memory policies, we train Qwen3.5-27B on SETA using SFT and GRPO, improving validation reward and achieving partial transfer to Terminal-Bench.

Reinforcement learning (RL) has become the standard paradigm for enhancing the complex reasoning capabilities of large language models (LLMs). To achieve sample efficiency, modern RL frameworks rely on importance sampling (IS). However, these algorithms suffer from an exploration-stability dilemma. Pure IS often leads to catastrophic training instability, while standard clipping mechanisms used to mitigate this instability strictly constrain the policy update budget. By formalizing the concept of Probability Capacity (Cap), we reveal that conservative clipping structurally stifles exploration by prematurely truncating the update budget for correct but low-confidence reasoning paths. To break free from these constraints, we propose Unbounded Positive Asymmetric Optimization (UP), a universal and plug-and-play objective. UP theoretically restructures the optimization process by anchoring the policy to its current state via the stop-gradient operator. This asymmetric design unleashes unclipped, stable gradients for positive advantages to maximize exploration, while maintaining standard clipping safeguards for negative advantages to prevent training instability. Furthermore, our formulation readily extends across different optimization granularities, including token-level (GRPO, DAPO) and sequence-level (GSPO) frameworks. Extensive experiments demonstrate that UP enhances exploration capacity and achieves superior reasoning accuracy across diverse RL algorithms (DAPO, GSPO, and GRPO), model architectures (Dense, MoE, and vision-language), and training modalities (language and multimodal), validating UP as a truly universal plug-and-play enhancement for RL-based training.

Generating realistic 3D human motions in real-time within interactive applications is key for animation, simulation, and humanoid robotics. While recent offline motion generation approaches offer precise control via text and kinematic constraints, they lack the inference speed required for interactive settings. Conversely, existing online methods enable real-time synthesis but often sacrifice controllability or struggle with complex text semantics and long-horizon goals due to limited context windows. In this work, we introduce ARDY, a streaming generation framework that bridges this gap by enabling high-fidelity motion generation controllable via online text prompts and flexible kinematic constraints. ARDY employs a hybrid representation that combines explicit root features with a latent body embedding, balancing precise trajectory control with efficient generative learning. We propose a two-stage autoregressive transformer denoiser that features variable history context and supports conditioning on flexible, long-horizon kinematic constraints. By training on a large-scale motion capture dataset and being directly conditioned on text labels and kinematic constraints sampled from ground truth poses, ARDY natively learns controllable generation that supports online prompting and flexible long-horizon goals. Extensive evaluations on the HumanML3D benchmark and the large-scale, high-fidelity Bones Rigplay dataset demonstrate ARDY's high motion quality and constraint adherence, validating the efficacy of our key architectural decisions. Finally, we demonstrate the method's practical versatility through an interactive demo featuring dynamic text control, diverse keyframe pose constraints, path following, and interactive locomotion control via mouse and keyboard.

GLP-1 减肥药并不能取代锻炼。研究人员跟踪了 130 名重度肥胖患者一年，他们平均减重 13.7公斤。研究人员将他们分成四组——运动组、服用 GLP-1 药 liraglutide 组，运动加 liraglutide 组，以及安慰剂组。研究结果显示，运动组的血管更健康，炎症水平也更低。虽然只服用 GLP-1 药有助于减轻体重，但不能改善血管健康。动脉壁越厚，动脉粥样硬化、血栓和中风的风险越大。运动组的动脉壁厚度减少了 6-7%，但服用 GLP-1 药和安慰剂组没有改善。运动组的炎症标志物水平也下降了。运动组的参与者平均每周训练约两个半小时，主要是健身车和循环训练。

多个案例显示中国法院支持数字资产的继承。法院认为游戏账户和微交易购买属于某种货币价值，因此玩家对这些资产拥有相关权利。法院拒绝标准的不可转让条款，认为这些条款无法阻止你继承或转让游戏(包括微交易物品)。其中一个案例是一位玩家的遗孀试图继承《征途》中的一把“黄金刀”。死者的游戏“情侣”对此表示反对，因为黄金刀是一件只能通过两个玩家协作游戏获取的道具，两个玩家的账户被连结为游戏中的情侣。法院发现另一名玩家曾出价人民币 5 万元购买黄金刀，表明该武器具有真正的市场价值。法院还注意到两名玩家在获取黄金刀上投入了大量的时间、精力和资金。因此法院认为黄金刀构成具有经济价值的虚拟财产，能成为死者遗产的一部分。然而由于它是由死者和游戏“情侣”共同获取的，法院最终得出结论：所有权由他们共同享有。因此只有死者的份额（50%）可以由他的继承人继承，而剩余的份额归游戏中的“情侣”。第二个案例涉及到了 5 个比特币和一个价值约 20 万元人民币的游戏账户。

布朗大学化学家提供了直接证据，证明重元素三键的传统解释需要修正。化学教科书称，原子通过共享电子形成化学键。每个原子共享一个电子形成成键电子对。电子对的强负电荷吸引着两个带正电的原子核，从而将它们结合在一起。一些元素会共享多个电子对，形成双键或三键。三键由一个σ键两个π键组成。σ键是头碰头的强键，π键是弱键，环绕在σ键周围。这种描述适用于轻元素。当原子核足够重时，爱因斯坦相对论会改变三键的结构，模糊了σ键和π键之间的界限。光电子能谱显示，碳-铋键不符合传统的一个σ键和两个π键构成的三键结构。其结构更像是由一个π键和两个σ-π杂化键构成。

在去年 12 月学校发生枪击案之后，布朗大学经济学教授 Roberto Serrano 首次让学生在家中完成期中考试。期中考试成绩显示大部分学生获得了满分或接近满分，他怀疑学生大规模使用 AI 作弊。因此决定将期末考试改为线下进行。他没有立即宣布期中考试无效，而是决定先看看期末考试的得分。如果期末考试得分的分布与期中考试的分布基本相同，那么他会将期中考试得分计入成绩。结果是 18 名学生退课，9 名学生没有参加期末考试。3 名学生得了零分，期末考试的平均分只有 48.6%——这是他所教班级迄今的历史最低分。此前期末考试的平均分从未低于 65%。只有少数学生的期末考试成绩与期中考试的成绩相近。

日本宇航研究开发机构(JAXA) 7 月 11 日宣布，成功测试了一枚可回收火箭 RV-X。本次测试总共持续了约 40 秒，火箭上升至约 11 米的高度，期间完成了升空、悬停、水平移动、直立着陆共 4 个动作。目前旨在大幅降低航天任务成本的可回收火箭是许多国家的研发重点。RV-X 计划将取代不可回收的 H-3 火箭。下一步 JAXA 还将测试 RV-X 的升空一百米回收测试。法国、德国也参与到了日本的可回收火箭合作研发项目中。作为日本的战略竞争对手，中国在可回收火箭研发方面的进展要快得多。

根据一项新研究，具有特定设计元素的人造环境可能会给大脑带来过度负担，导致视觉不适和压力。视觉不适是指人在看到某些图像或环境时所体验到的不适感，可能表现为眼睛疲劳、偏头痛、阅读困难，或者在他人毫无问题的情况下感到不堪重负。条纹图案、凌乱的内饰、高对比度颜色、闪烁的灯光，甚至是超市中密集的货架，都可能导致视觉不适，这有助于解释为何某些空间会让人感到不舒服。现代人造环境与视觉系统在演化过程中高效处理的自然场景存在显著差异。研究还发现，现代环境对敏感人群影响更大，对感官输入更敏感的人群（如偏头痛、自闭症、注意力缺陷多动障碍、阅读障碍或癫痫患者）可能受到的影响更强烈。

新冠疫情加速了被称为安静辞职(quiet quitting)的现象，年轻一代的上班族将工作热情不高的态度视为某种形式的“辞职”，他们还想继续领工资，但仅完成最低工作要求，把精力放在工作之外的事情上。韩国嘉泉大学的研究人员调查了权威型领导如何推动中国中小企业员工的安静辞职现象（即躺平）。他们收集了 363 名中国中小企业员工数据。结果显示权威型领导通过增加工作倦怠间接导致躺平，而非自愿出勤通过放大倦怠加速躺平。研究有助于更深入地理解权威型领导带来的有害后果，阐明躺平在中国文化背景下的出现和演变。

根据发表在《自然》期刊上的一项研究，人形机器人成功完成切除活体动物胆囊的手术。人形机器人并不具有自主能力，它们并不会取代医生，而是由外科医生远超操作。远程操控的人形机器人为活猪完成两例微创胆囊切除手术。如果该方法被证实适用于临床，外科医生就可以利用人形机器人，在资源有限、无法安装专业且昂贵手术机器人的小型医院和诊所远程开展机器人辅助手术。人形机器人相比专业手术机器人更便宜，占用的空间更小，而且易于部署，能部署到从偏远地区到战场甚至太空。研究人员利用宇树科技的 G1 人形机器人。最便宜的 G1 基础型号起售价 13,500 美元，配置灵活机械手以及运费之后费用会超过 6.7 万美元。相比下 Intuitive Surgical 的达芬奇手术机器人费用在 50 万到数百万美元之间。宇树科技机器人的缺陷是需要频繁重校准，耗时更长。

OpenRouter 的数据显示：美国企业每周调用中国 AI 的占比按代表数据处理量的“词元”统计，自 2 月起突破30%，峰值达 46%。相比下 2025 年上半年仅 4% 左右。背景是美国本土 AI 使用成本升高。美国OpenAI 及美国 Anthropic 等高端模型的性能不断提高，可自动处理长时间、高复杂度的任务。但随着企业在内部业务、面向客户服务中广泛使用 AI，词元的消耗量增加，使用成本增加。OpenRouter 平台拥有 800 万用户，以工程师群体为主，每输出 100 万词元（约对应 70 万英文词汇）的收费标准方面，Anthropic 的“Claude Opus 4.7”收费 25 美元，而最热门的 DeepSeek V4 Flash 仅收费 0.18 美元，成本不足前者的 1%。

Google 表示世界杯期间其搜索量创下历史纪录，每秒查询量的峰值是在阿根廷与埃及比赛中间射入制胜球之后。 这一里程碑式的成就正值 Google 试图证明其传统搜索引擎在 AI 聊天机器人日益普及的时代仍能保持其重要性之际。Google 仍然占据着九成的搜索市场份额，其股价过去一年翻了一番多，第一季度营收增速是自 2022 年以来最快的。Google 表示赛后搜索量最高的查询是“阿根廷 vs 埃及（argentina vs egypt）”。在全球范围内，用户还搜索了“阿根廷 vs 哥伦比亚”和“梅西在世界杯上进了多少球”，以及“比赛中一名球员撞击其他球员叫什么”和“这是梅西的最后一届世界杯吗”。

美国国会议员正在调查美国公司使用中国 AI 模型。议员们担心审查、安全风险，以及美国 AI 公司的模型是否过于昂贵或限制过多。Cursor 和 Airbnb 等公司是调查重点。众议院国土安全委员会和众议院中国问题特别委员会致函 Cursor 和 Airbnb 询问他们使用中国 AI 模型的风险。美国部分政府部门已禁止使用 DeepSeek 等中国模型，但美国公司并未被禁止使用中国 AI 模型。有很多美国公司一直用中国 AI 模型降低使用成本，其中就包括了即将被 SpaceX 公司以 600 亿美元收购的 Cursor 公司，该公司的 Composer 2 模型是基于北京月之暗面（Moonshot AI）的 Kimi 模型。美国国会还在调查美国公司的开源 AI 模型战略，确保美国公司不需要在昂贵或受到限制的本国模型与廉价且功能强大的中国 AI 模型之间做选择。

根据发表在《Frontiers in Psychology》期刊上的一项研究，父母对屏幕和智能手机的上瘾可能会对孩子的发育和心理造成长期的负面影响。研究显示，对设备管理不当的看护者可能会加剧“不安全依恋”，使得人际关系变得更加焦虑和回避。这项研究基于美国 600 名 12-17 岁的未成年人的调查，儿童表示他们感到被盯着屏幕的父母边缘化或忽视。研究人员表示，缺乏安全依恋的孩子可能会缺乏自信或表现出较低的自我意识；在人际关系和亲密关系方面表现出困难；并不愿意承担取得成功所必需的风险。
