As we move through the world and carry out everyday tasks, we encounter objects that may become relevant only later. We are capable of recalling where we left something or what was inside a container, even without knowing we would need it …

Unsiloed 发布 Higher-Order Extraction，可从页面原始数值生成确定性代码，计算出文档中并未直接印出的数字，每个结果都能追溯到页面。若文档某处恰好印有答案，系统会与自身结果比对：一致则置信度提升，不一致则置信度降为零。

Modern language models undergo reinforcement learning with verifiable rewards (RLVR) on top of already-trained checkpoints. A key promise of RLVR is the discovery of new reasoning strategies. In principle, a model can sample novel ideas ab…

Conditional memory architectures such as DeepSeek Engram use input n-grams to look up learned embeddings, expanding the capacity of large language models (LLMs) with limited additional computation. Beyond model scaling, this architecture h…

CZ Biohub 牵头一项 18 亿美元计划，训练 AI 模型预测细胞行为以加速药物研发，其中 4 月已承诺 5 亿美元用于五年期 Virtual Biology Initiative。

Real-time robot control demands enough visual history to infer motion and task progress, but processing that history can delay action. We present Long-WAM, a model-system framework for scaling the context of causal world-action models unde…

Heavy-tailed noise has been widely observed in modern machine learning, motivating the use of methods like gradient clipping and normalization. While these methods are well understood in centralized settings, much less is known in decentra…

Smith 因用约 1 万个机器人账号和 AI 生成歌曲伪造流媒体播放量骗取版税，被判 18 个月监禁，并须没收 8,091,843.64 美元非法所得。DOJ 称这是此类起诉中的第一案，指出其行为摊薄了平台版税池、损害真实艺术家收益；其律师以当事人未实际持有 800 万美元、已获唱片公司工作为由争取缓刑，DOJ 则以持续欺骗手段和说谎为由主张从重判刑以示震慑。

Vision-language-action models (VLAs) are strikingly sensitive to instruction phrasing and do not inherit the language robustness of the vision-language models they are built on. A one-word edit can move success by tens of points: $π_{0.5}$…

GNN-to-MLP distillation aims to retain the predictive accuracy of a message-passing teacher while deploying a graph-free MLP at inference. Existing methods mainly transfer node-wise predictions or use confidence-based reweighting, but they…

Machine unlearning asks for a deletion algorithm whose output is close to retraining from scratch without the selected forget examples. In this work, we study forget-only unlearning, where the deletion algorithm receives only the trained m…

Latent world models have shown a remarkable ability to predict future states and to plan in the real world. In practice, however, we lack a principled way to estimate how their capabilities scale with model size, data, and compute, an open…

Language-model agents are increasingly asked to carry out open-ended scientific research, yet their results are usually graded against a known answer, a rubric, or a language-model reviewer, none of which can tell whether a new scientific …

llama.cpp 可通过 ggml RPC 后端在异构设备间分布式推理，作者 Georgi Gerganov 表示这是高级设置，后续会让普通用户更容易使用。被引用的实测称，MiMo 2.6 Flash 的原生 mxfp4 权重可跨 RTX 6000 GPU 与 M5 笔记本以 40 tokens/sec 通过 10 GbE 运行，llama.cpp 开箱即支持。

Prompted embedding models have recently received increasing attention, particularly for retrieval, where detailed retrieval instructions are provided as part of the retrieval prompt. Several new datasets and studies have examined this sett…

Large language models are increasingly applied to tasks grounded in long, heterogeneous information sources. Conventional Retrieval-Augmented Generation (RAG) relies on fixed similarity-based retrieval, while agentic variants adapt queries…

Many of the questions now put to large language models have no correct answer to score against: what a policy is worth, which option a user should choose, how to weigh competing values. Stated-preference economics has faced this problem fo…

Google 将 SynthID Detector 向公众开放，任何人都可检测图片、视频或音频是否由 Gemini、Veo、Lyria 等 Google AI 或其合作方模型生成，支持 JPG、PNG、MP4 和 MP3 格式。

Online learning is an attractive framework in many domains because it permits well-defined learning even when data are dependent or chosen adversarially. This generality, however, comes at a steep price, introducing significant statistical…

Docker 发布 docker-agent，一个 Docker CLI 插件，用 YAML 声明式配置构建、运行和分享 AI 智能体，无需写代码，命令为 docker agent。

Robot foundation models provide strong visuomotor control, yet their performance can degrade when object positions or task instructions change. Further improvements often require post-training on substantial robot data, which can be costly…
