今天上午，科技股迎来反弹，AI应用全面走强，华为盘古、多模态AI、AI智能体等板块大涨。 科技股反弹主要有两方面因素催化： 一是北京时间11月15日，巴菲特旗下伯克希尔·哈撒韦公司披露2025年第三季度持股报告（13F）。在巴菲特宣布将于今年底正式交班后，伯克希尔在第三季 度出手买入美国大型科技股——谷歌-A。据披露，伯克希尔买入谷歌-A将近1785万股，对应季末市值约为43亿美元。这是伯克希尔在第三季度买入最多的 标的，也是唯一新增持股。 今天上午，谷歌概念表现强势，腾景科技涨超12%，中际旭创、长芯博创、胜宏科技等个股上涨。 近期美股科技板块回调，尤其是AI相关龙头股显著下跌，市场上对"AI泡沫"的讨论逐渐增多。有观点认为，当前的AI可类比2000年的互联网泡沫。此次伯 克希尔买入谷歌-A，在一定程度上减缓了市场对"AI泡沫"的担忧。 国信证券表示，2025年的AI行业与2000年的互联网泡沫，在估值基础、盈利能力和投资实质上截然不同。AI是一场将持续数年的"基础性转变"。 二是AI应用方面的利好。11月13日，OpenAI发布GPT—5.1系列模型。此次发布包括两款已上线版本——GPT—5.1 Inst ...

克雷西 发自 凹非寺 量子位 | 公众号 QbitAI 不仅能力超强，Gemini 3的关注度也是相当火热。 Gemini 3还未正式发布，"超前点映"已悄悄亮相。 许多网友都分享了自己的一手实测，表示Gemini 3的表现实在是强到飞起。 它可以将不同游戏缝合到一起，在网页中创建一个《我的世界》风格的塔防游戏； 也可以用SVG动画直接在网页中复刻一个Switch，还是带屏幕能模拟宝可梦的那种。 需要将APP更新然后打开，并使用基于Gemini Pro 2.5的Canvas功能，实际调用的就是Gemini 3。 这名网友还放出了APP和网页端的对比 ，同样使用2.5版本的Canvas，结果表现差异明显。 甚至有机构发起了猜猜乐，消息还被谷歌CEO劈柴哥亲自转发，并配上了两个耐人寻味的emoji符号。 Gemini 3"超前点映"上线 据网友介绍，Gemini 3"超前点映"的入口藏在APP当中。 不过随后又有其他网友表示，网页端也已经上线了。 除了官方途径之外，一些第三方平台，例如OpenRouter当中，也据传藏有Gemini 3.0。 想亲自体验的话可以按照上面说的试试，接下来我们继续看Gemini 3都 ...

长期以来，多模态代码生成（Multimodal Code Generation）的训练严重依赖于特定任务的监督微调（SFT）。尽管这种范式在 Chart-to-code 等单一任务上取得了显 著成功 ，但其 "狭隘的训练范围" 从根本上限制了模型的泛化能力，阻碍了通用视觉代码智能（Generalized VIsioN Code Intelligence）的发展 。同时，「SFT- only」的范式在确保代码可执行性和高视觉保真度方面存在显著瓶颈 。 在此背景下， 中科院 & 美团研究团队推出了 VinciCoder ，一个旨在打破 SFT 瓶颈的统一多模态代码生成模型。VinciCoder 首次将强化学习的奖励机制从文本域 转向视觉域 ，提出 视觉 强化学习 （ViRL） ，专攻 SFT 无法解决的视觉保真度难题。 本文提出的系统性框架 VinciCoder ，通过 "大规模 SFT + 粗细粒度 ViRL" 的两阶段策略，有效统一了从图表、网页、SVG 到科学绘图（LaTeX、化学分子）等多 样化代码生成任务 。 论文标题：VinciCoder: Unifying Multimodal Code Gener ...

那几年，他被DeepMind拒了三次，连签证都差点失效。 在X上，流传着一个关于PyTorch创始人Soumith Chintala的故事。 他出身普通，数学不好，被美国12所大学拒绝。靠着一张短期签证去美国，无学位、无资金、无计划。 可他没放弃。2017年，他写出了PyTorch。 那个被主流嫌「没前途」的开源项目，一夜之间成了香饽饽。 人们才发现，这个影响全球AI走向的工具，竟出自那个被拒12次的「失败者」之手。 反复被拒的十年 Soumith的起点很普通。 他出生在印度海德拉巴，读一所二本的学校——VIT Vellore。 数学不好、履历普通，这在印度那种内卷到骨子里的教育体系里，意味着前路不太妙。 但他还是想出国读研。那年他拿着1420分的GRE，申请了美国12所大学，可全被拒了。 后来，Soumith Chintala拿到一张J-1签证去了美国，却没有明确的方向，也没钱继续念书。 申请第二轮硕士时，又被拒到只剩南加州大学和NYU。留学梦差点断在签证那一关，那时候几乎所有人都觉得他要放弃了。 可他没有妥协。他选择从亚马逊开始，做一个最不起眼的测试工程师。 Soumith被DeepMind拒了三次，甚至 ...

自2022年11月ChatGPT发布以来，生成式人工智能高速发展，大模型竞赛白热化，性能指标不断刷新，多模态能力持 续提升。AI智能体能自主调用工具，完成越来越复杂的任务。AI大模型厂商纷纷声称，通用人工智能（Artificial General Intelligence，AGI）时代即将到来。 与技术高歌猛进形成鲜明对比的是商业落地的滞后。美国Ramp AI Index数据显示，美国公司采用付费AI产品的比例近 期有停滞迹象，甚至出现下滑。 麻省理工学院在2025年7月的一份研究报告（The GenAI Divide: State of AI in Business 2025）中指出：95%的生成式AI 应用项目效果不佳或中途夭折。这份报告甚至引发了美股震荡。 当"所有行业都需用AI重做一遍"的豪言遭遇"AI项目高失败率"的现实，我们不得不追问：AI从酷炫的功能到真实的产 业应用，究竟卡在了哪里？又该如何穿越迷雾，实现真正的价值闭环？ 01 根据我的观察，目前多数企业仍停留在直接套用AI工具的阶段，既未拆解工作流，也未评估AI能力与业务需求的适配 性，未能形成投入-数据-效益的飞轮，结果自然不如预期。 02 ...
