I kept looking for a simple way to build small websites with reusable components. Wanted to write...

GitHub 官方博客发布 GitHub Copilot app 新手教程，介绍用 /create-canvas 技能通过自然语言描述生成可自定义的 canvas 界面。

Reasoning models often generate very long reasoning traces, making inference computationally expensive. Existing approaches typically improve efficiency either through inference-time early-stopping mechanisms or by explicitly encouraging s…

We give a gap-free differentially private algorithm for the principal component analysis (PCA) problem with Gaussian data.

Recent literature has shown a strong connection between optimization and sampling. We develop the corresponding first-order theory for diffusion models. First, the SDE-based reverse-time flows of overdamped and underdamped Langevin diffusi…

微软本周发布的新 Surface 机型满足 Copilot+ PC 要求但不再使用该名称，Surface 部门副总裁 Brett Ostrum 称其达到此前的 Copilot+ 标准。

Three batch commits swept a gated post onto this live site. What broke, why globs did it, and the two checks that now run after every deploy. Readers debate where pipeline gates belong: prose or code.

微软 CEO Satya Nadella 在 Alex Heath 的播客中表示，智能体（Agent）时代的市场规模将比云业务大几个数量级，并称这可能是史上最大的 TAM 扩张。访谈还涉及新 Copilot 的发布、基于 OpenClaw 的智能体 Autopilot、微软与 OpenAI 的关系及自研模型，以及 AI 安全与监管等话题。

Google DeepMind新西兰技术专家Robert O'Callahan因AI风险离职，称AI"当前变化速度过快"，认为"在不久的将来以ASI为目标本质上不负责任"。他曾参与让AI更便宜、更快的芯片设计工具开发，如今表示无法再为此辩护，并警告认知投降、AI引发的精神病与孤独、权力集中、经济冲击、网络安全风险及问责缺失等问题。

Generative AI systems are increasingly used, but aligning their outputs with user requirements poses a continuing challenge. Here, we aim to ensure that the distribution of an attribute of an AI-generated output aligns with a user-specifie…

Large language models (LLMs) implicitly infer attributes of their users and adapt their behavior accordingly, yet these beliefs remain difficult to inspect and causally manipulate. We introduce Belief Self-Distillation (BSD), a unified rea…

Low-rank adapters (LoRA) make it cheap to fine-tune a large language model once per task, but combining several independently trained adapters into one model remains difficult: merging the updates in weight space causes interference, retra…

Anthropic 在科学博客称，物理学家 @4gravitons 发起挑战后，Claude 在 Claude Science 中依据单个提示词 largely unsupervised 地运行数天，在平面 N=4 超杨-米尔斯模型中完成九圈散射振幅计算，总成本约几千美元。

Direct feedback alignment (DFA) trains hidden layers through fixed random projections of output error. With tanh hidden units and independent sigmoid outputs, plain stochastic gradient descent can stall near the loss of a constant predicto…

在世界模型中训练客体永久性 论文：https://huggingface.co/papers/2609.28654

We investigate whether natural-language documentation helps coding agents resolve software issues, and we build the tools to construct and evaluate it. We introduce a roundtrip benchmark that scores code descriptions by whether code regene…

Decision Transformer performance degrades on long rollouts because the conditioning context drifts out of the training distribution. We show that this drift is visible through the model's own next state prediction error, which rises during…

Claude Opus 5.5 遇上 Runway MCP。 将 Runway 直接接入 Claude，即可用 Gen-4.5、Seedance 2.5、GPT Image 2、Kling 等生成精美图像和视频，就在你的工作环境中完成。几秒即可通过下方链接接入。

Uneven rotation and dropped frames make equal-angle assumptions unreliable for turntable reconstruction. We present OC-GS, an object-centric Gaussian splatting that refines each image's angle while maintaining a shared camera, rotation axi…

Many LLM training and inference methods, including RL and test-time scaling, depend on repeated sampling, but benefit only when the responses meaningfully differ. Self-training faces the same challenge: training data is typically construct…

Deep learning has substantially accelerated the calibration of complex stochastic-volatility models, but neural point calibration alone does not capture the uncertainty remaining after an implied-volatility (IV) surface has been observed. …

Claude Tag 在 Slack 现已支持个人连接器，可安全访问用户有权限的 Drive 文档、Salesforce 账户或数仓表，Teams 版今日可用、Enterprise 下周可用。

In my last post, I talked about why AI has become part of my workforce. I have too many things I...

Conversational AI tools are entering children's everyday experiences, and schools are interested in adopting them. However, successful classroom integration depends not only on the technology but also on the work teachers do to make it usa…

AI tutoring could markedly improve learning outcomes for students in developing regions such as Vietnam, yet the two obvious paths both fall short. Cloud assistants such as ChatGPT route sensitive student data to foreign servers---violatin…

UpGuard 研究发现托管在 Supabase 上的约 1.6 万个数据库存在不同程度的个人数据公开暴露，可公开访问姓名、地址、电话号码及部分密码和认证 token。

We show that neural network weights can be explicilty fintuned to admit a smaller grammar. Weight Pair Encoding (WeightPE) does so by placing a lossy Re-Pair compressor inside a straight-through estimator. The int8 weights of the network a…

Multi-agent LLM systems are often expected to improve as team size increases, yet the scaling behavior may depend on task structure. Our central contribution is to introduce Steiner's taxonomy of group tasks as a framework for analyzing mu…

Large neural networks can be compressed by rounding or "quantizing" their weights to numbers that admit representations with fewer bits. One algorithm for quantization, OPTQ, progressively quantizes the weights of a neural network so that …

Online learning in non-stationary environments requires models to adapt rapidly from streaming data under strict computational constraints. A principled approach casts online learning as Bayesian state tracking, where model parameters are …

两位密码分析者分别使用 OpenAI 的 Astra 和 Anthropic 的 Claude Opus 5 破解了两则长期未解的 Enigma 密文。

Ensuring online safety through content monitoring had raised Hate Speech Detection as a crucial task to be addressed. By essence the task demands the capture of contextual cues, which are essential for a precise understanding of the conten…

John Gruber 在文章《Muse Looks Cute, but Looks are Deceiving》中评价 Meta 的 Muse：每个用户可获得一个运行在 Meta 云端、属于自己的持久化 Linux VM，以易安装易用的吉祥物形式呈现，他认为这是首个消费者可用的智能体 AI 系统。

Disaggregating the two stages, Prefill and Decode, onto separate GPU pools is now a standard optimization for (text-only) LLM serving. However, multimodal LLMs (MLLMs), which add a third phase, Encode, pose new challenges for resource allo…
