GitHub 工程师 Josh Black 复盘将 Primer 设计系统从 CSS-in-JS 迁移到 CSS Modules 的历程。截至 2024 年 12 月 Primer 全部组件迁移完成，服务端渲染时间减少 55%，组件初始化时间减少 25%。

Ricursive Intelligence 联合创始人 Anna Goldie 与 Azalia Mirhoseini 将在 TechCrunch Disrupt 2026 登台，讨论 AI 设计芯片硬件、构建自我改进系统。

RSIAgent 用课程智能体生成练习任务、执行智能体用代码解题、独立验证器校验结果，练习先覆盖相关任务再深入真实任务的难例。论文称，先广泛探索再攻难例的智能体在 4 项任务上平均得分 74.54%，直接上手难例仅 56.50%。该方法旨在替代为新应用收集数据并重训的高成本做法。

Distributionally robust optimization (DRO) provides a principled framework for learning under distribution shift, but its practical use is hindered by the difficulty of evaluating worst-case risks for nonconvex loss functions. We study a p…

Inference in LLMs is conventionally a fixed-depth, fixed-order forward pass through every layer, regardless of how difficult the input is. The human brain does not work this way: using the thalamus as a central hub, it routes information f…

AI 正在改变学习的延迟，其影响超过可获取知识量的变化。 Jamie Beaton 的故事很极端：在打造快速增长的企业 Crimson Education 的同时，拿下了 12 个高等学位。

The Model Context Protocol (MCP) provides a common interface through which AI applications discover and use external resources and tools. It allows language-model agents to ground their reasoning in current system state and interact with h…

Vision-Language Models (VLMs) exhibit remarkable zero-shot generalization, yet they often encode unwanted or hazardous stylistic domains such as idealized textbook diagrams in medical AI or cartoon vehicles in autonomous driving. Approxima…

Contemporary large language model (LLM) chat systems treat conversation history as an immutable sequence of turns that defines the model's working context. However, user intent in real interactions is not static: it evolves through correct…

Time-series carry structure simultaneously at multiple scales (fine-grained variation, mid-range motifs, and global properties) and downstream tasks operate at correspondingly different scales. Most existing self-supervised learning approa…

Humyn Labs 推出 BRIDGE ASR 2.0，用真实双人对话评测 23 个语音识别模型，覆盖 18 种印度语言及西班牙语、葡萄牙语、越南语。其核心指标 code-switch F1 检验句中混用的英文词是否保持英文，排行榜支持按语言和指标筛选，方法论与评测数据公开。

Large video diffusion models offer expressive priors for embodied prediction and learning, yet their many-step sampling remains costly for interactive downstream use. Distribution Matching Distillation (DMD) enables few-step video generati…

美团 LongCat 发布 LongCat-2.5-Preview，作者转发时指出定价与之前一样。该模型 1.6T 参数、约 48B 激活、1M-token 上下文窗口，原生多模态，面向长程任务，覆盖终端、浏览器、GUI、电子表格和设计工具等场景。API 入口 https://longcat.ai/platform/ ，对话入口 https://longcat.ai/chat/ 。

Retrieval-augmented generation (RAG) is often used to address outdated knowledge by providing external evidence. But retrieval helps only when that evidence is still valid. We identify a temporal alignment failure, stale-document poisoning…

Whether an information extraction pipeline should process page images or parsed text depends on the document, and the answer flips across the layout spectrum. We study this trade-off under a constraint that rules out (closed) cloud service…

Have you ever asked AI to do something very specific and it did almost everything right? Except the...

Morphology--control co-design jointly optimizes an agent's body structure and control policy as an integrated embodied system. However, existing methods typically model morphology design and control with separate networks coupled only indi…
