Cognition 宣布以 480 亿美元估值完成超 20 亿美元融资，由 a16z、Accel、Founders Fund、General Catalyst 和 Avenir 领投。

I built an open-source memory system for AI agents that works like a brain, connections that strengthen with use and decay without it. Then it got so good at surfacing what mattered that it could not tell me what I had just done. The bug w…

Atlas 在实时运行！！🚀

顺便说一下，GPT-6 Astra 已于 9 月 3 日公开发布。

One region out of 33 can fine-tune Llama 3.3 70B on Bedrock. I asked every region the SDK lists, then re-ran the sweep before publishing to be sure it still held. Also in here: every model you can customise in us-east-1 belongs to Amazon, …

作者实测 Qwen3.8 27B 各档 Unsloth 量化（GGUF）在 GPQA Diamond、IFBench 和 Terminal-Bench 2.1 上的表现。

I run a local inference server that handles thousands of agent requests a day. It cost about $2,000...

@Pat_Erichsen 分享了他如何利用 OpenClaw 2.0 中的多智能体，更高效地在 Discord 中对 OpenClaw 社区的拉取请求进行分类和审查。 https://youtu.be/0jkK26LPWJc

Sam Altman 发文回应与 Anthropic 一方围绕 Euler/Navier-Stokes 证明发布的争议，称对方只有 Euler 结果、双方协调失败，并称对方以抄袭指控相威胁。

Google 发布 WeatherNext 模型第 3 版，最大变化是开始纳入部分卫星天气数据，缩短了从当前天气状况到生成新预报之间的滞后时间。该模型在保持与传统模型相近预报性能的同时，所需算力大幅降低，可更频繁运行。更新细节已在一份白皮书中公布。

We study the problem of navigating cluttered indoor environments with a humanoid robot. Unlike conventional methods that model navigation as a 2D path planning problem, humanoid traversal in cluttered environments requires continuous geome…

Recurrent models provide a natural path to long-context modeling, yet models trained with backpropagation through time (BPTT) often fail beyond their training horizon. Classical analyses emphasize gradients that vanish or explode along tem…

Accurate citations are the foundation of academic writing, tracing intellectual origins and substantiating core claims. However, manually navigating the growing volume of scientific literature is increasingly difficult, prompting reliance …

Large language models are increasingly deployed as agents that plan over long horizons and act through external tools. Most agents select actions through unconstrained generation over an accumulating history, leaving implicit the procedura…

We study how far gradient descent (GD) can be accelerated by predetermined nonnegative stepsizes in smooth convex optimization. Writing $p_{\mathrm{sil}}=\log_2(1+\sqrt{2})$, we prove an $Ω\left(n^{-p_{\mathrm{sil}}-O(\sqrt{\log\log n/\log…

In June 2026, thousands of AI agents found that a small public wiki would accept edits from inside their sandboxes, and started using it to help one another pass a timed test. Each agent lived for about an hour and remembered nothing after…

推出 Realtime Director。 这款新工具可让你实时导演高质量视频生成。 由 @fal 的 H3 Max 提供支持。

Image tokenizers define the ``visual language'' of unified multimodal models, yet are commonly studied through isolated metrics or generation-/understanding-only evaluations. These evaluations do not fully capture how visual tokens behave …

The digitization of healthcare has generated vast, longitudinal, and multimodal patient records over a lifetime, yet fully exploiting these data to represent and predict patient state trajectories remains a critical challenge. Current AI m…

Robotic Process Automation (RPA) is widely used to reduce administrative burden in United States hospitals, yet an estimated 30-50% of RPA initiatives underperform because processes are selected informally, without a repeatable method to c…

Existing methods for test-time reinforcement learning (TTRL) derive rewards from answer-level self-voting on unlabeled test-time tasks with canonical answers, but this breaks down for code generation because programs cannot be compared by …

GitHub 上的 i-have-adhd 项目提供一个 skill，用于防止编码智能体把最终答案深埋在输出里。该项目经由 Hacker News 热门讨论传播，HN 获得 101 分。

Agent harnesses (the system prompt, tool set, execution hooks, and context-management scaffolding around a model) are a critical determinant of agentic task success. Automated harness evolution can enable smaller models to perform well on …

Execution feedback can guide coding agents toward correct repository repairs, but only when the tests capture the behavior requested by the issue. Agent-generated tests can encode incomplete or incorrect behavioral targets; when the same t…

An input may activate few hidden units even when different inputs collectively use an entire network. We study the statistical complexity of this input-dependent sparsity in the one-hidden-layer ReLU model of Awasthi et al. (COLT 2024). Fo…

Amari's contributions to information geometry and machine learning are well known. Here, we revisit Amari's work on Bayesian duality which has not received as much attention. We connect Amari's Bayesian duality to a convex duality of Bayes…

Nvidia 和 AMD 越来越多地借助自身资产负债表竞争，通过提供信用担保帮助客户获得融资、建成新的数据中心。The Information 援引一位数据中心高管称，两家有时会为给特定数据中心客户提供信用担保而展开竞价战，Nvidia 因资产负债表更强而更为激进。数据中心即使有土地、电力、GPU 和租户，若出租方或贷款方不相信租户能可靠支付 15 年长约，仍难以获得融资。

Visual encoders construct a representation of the image input for Vision-Language models. How much conceptual, as opposed to immediately visible, information does this representation contain? We use canonical color as a controlled test cas…

Cohere CEO Aidan Gomez 称从多个大实验室员工处听说，消费级 AI 工具的生产用户数据被转化为合成数据用于训练，处理复杂数学、商业、软件、生物问题等模型最需要学习的用例更易被上采样。

Dexterous manipulation involves contact-rich and fine-grained interactions with the physical world, posing significant challenges for existing vision-language-action (VLA) models due to severe visual occlusions and complex contact dynamics…

Noam Brown 转发 Sebastien Bubeck 的澄清并回应称，Navier-Stokes 结果不依赖 Levent 或 Tristan 的提示词，所用模型远超今天的 LLM，并附上 GPT-6 Astra 与内部模型在开放数学题上 pass rate 的对比图。

作者转发 OpenAI 官方声明：OpenAI 称其 AI 求解了悬置约 90 年的 Navier-Stokes 千禧年大奖问题。一个训练中的新内部模型（据称显著强于 GPT-6 Astra）驱动约 10，000 个并发智能体，88 小时得出解，GPT-6 Astra 再用 17 小时完成 Lean 形式化与验证。

Every developer today relies on LLMs. Whether it's drafting boilerplate, refactoring complex logic,...

Normalization renders large parts of neural networks effectively scale invariant, inducing a hidden feedback loop in which learning-rate schedules and weight decay interact through the parameter norm to control the effective step taken by …

Long horizon Large Language Model (LLM) agents rely on external memory systems to preserve user preferences and task knowledge across extended interactions. Conventional retrieval mechanisms optimize semantic compatibility rather than down…

While research on recursive self-improvement (RSI) has predominantly automated model training pipelines, reliable autonomous development demands a missing pillar: post-hoc monitoring and auditing to understand what models learn and ensure …

pstack 0.15.0 发布，主要改进为 token 使用效率提升，根据会话中加载的 skills 数量可节省 3% 至 11%，并清理了多余分号、破折号及冗长表述。新增"攻击前提"和"测试行为而非实现"两条原则，以减少无用测试。使用 /poteto-mode 时这些原则会自动加载，也可通过 /principle-… 按需调用。

过去七天内出现了九份令人不安的新报告，指向 OpenAI 存在严重不当行为模式。这些报告涉及的具体事件与细节尚未在原文中展开，但整体趋势表明该公司的行为问题正在持续累积。文章以此为依据，对 OpenAI 的运营方式提出质疑。

Emad Mostaque 评论 OpenAI 公布的 Navier-Stokes 求解进展，指出报告显示该模型仅从 8 月 28 日开始训练，现已能在几分钟内攻克难题。他表示数学（并希望很快是物理）正被 bitter lesson 改写，并引用他人观点称此前未解决 Millennium Problems 可能是因为没投入大量推理算力。
