IDEA团队 投稿 量子位 | 公众号 QbitAI 3D模型的实例分割一直受限于稀缺的训练数据与高昂的标注成本，训练效果有待提升。 近年来使用成熟海量的2D实例分割数据来辅助实现3D实例分割成为了一个极具潜力的研究方向，但实现思路不尽相同。 近日IDEA计算机视觉与机器人研究中心 （CVR，Computer Vision and Robotics） 的张磊团队提出了一种名为OVSeg3R的开集3D实例分 割学习新范式。 与传统训练范式相比， OVSeg3R无需对输入点云进行人工后处理 ，也不需要高成本的物体3D掩码人工标注，大幅降低了3D实例分割的训练 成本，有望让3D实例分割从"只能识别已知类别"的闭集模式，到"可识别未知类别"的开集模式实现商业落地，广泛应用于 自动驾驶、智能家 居、机器人导航等需要精准3D场景理解的领域 。 △ 视频1：从视频到开集空间感知工作流 △ 视频2：OVSeg3R与闭集SoTA模型 （SegDINO3D） 感知结果对比可视化 一、3D感知的"卡脖子"难题 3D实例分割，就是让计算机像人眼一样，看懂三维空间里的每一个物体，以及精准勾勒出每个物体的边界范围。 这项技术是自动驾驶、 ...

Core Insights - The article discusses a groundbreaking experiment by Cursor, where hundreds of AI agents collaboratively developed a usable web browser from scratch, producing over 3 million lines of code [2][3]. Group 1: Experiment Overview - The project, codenamed FastRender, resulted in a browser with a rendering engine written in Rust and a custom JavaScript virtual machine [2]. - The browser is described as "barely usable," with performance significantly lagging behind established browsers like Chrome, but it can render Google's homepage correctly [3][4]. Group 2: AI Model Utilization - The success of the experiment relied on OpenAI's GPT-5.2-Codex, which is designed for complex software engineering tasks and can autonomously plan and execute coding tasks [5][6]. - GPT-5.2-Codex incorporates a technique called "Context Compaction," enhancing its ability to maintain logical consistency while handling large codebases [8]. Group 3: Multi-Agent Collaboration - Cursor developed a multi-agent collaboration architecture to enable hundreds of AI agents to work simultaneously without conflicts [12][18]. - Initial attempts at a flat collaboration model led to significant inefficiencies, prompting a shift to a hierarchical structure with planners, workers, and judges to streamline the process [15][18]. Group 4: Insights and Challenges - The experiment revealed that the general GPT-5.2 model outperformed the specialized GPT-5.1-Codex in long-term autonomous tasks, while other models like Claude Opus 4.5 were better suited for interactive scenarios [21]. - The design of prompts was found to be more critical than the model itself, emphasizing the need for extensive trial and error to guide AI agents effectively [22]. Group 5: Future Implications - The experiment sparked significant industry discussion, with predictions that the marginal cost of software development could approach zero as token costs decline [25]. - Despite existing challenges, such as planning responsiveness and agent overactivity, the experiment demonstrated the feasibility of scaling autonomous coding capabilities through increased agent numbers [29].

闻乐 发自 凹非寺 量子位 | 公众号 QbitAI Gemini又偷偷藏不住了。 内部数学版学霸模型 FullProof 全程不联网，直接帮数学家证明了代数几何领域的一个新定理—— Gemini的证明严谨、正确、优雅……这是我本人也会引以为傲的见解。 那咱就来看看怎么严谨、怎么优雅的？？ Gemini埋下关键思路伏笔 0亏格映射到旗簇空间的motivic类等价结论。 好好好，咱先来简单理解一下，就是把一堆无缺口的橡皮筋按一定的规则套进层层嵌套的盒子里，橡皮筋所有的摆放方式就对应了一个空间； 新结论证明这个空间可以用「一般线性群+仿射空间」的组合来表示，后续研究相关问题直接分析这个简单的样板就行。 在这项研究中，Gemini埋下关键思路的伏笔，甚至能独立给出反例，精彩表现直接让美国数学学会主席都点赞： 这篇论文聚焦的核心问题，是确定0亏格映射到旗簇空间的motivic类等价形式。 旗簇空间 是一种由不同维度子空间层层嵌套构成的几何结构，类似大盒套中盒套小盒的收纳系统； 0亏格映射 对应把无洞的光滑曲线（像橡皮筋）放进这个嵌套空间的所有摆放方式； 格罗滕迪克群 代数几何里一个用来给几何空间分类归档的数学工具，专 ...
