这标志着 RLVR 的模型调优正在逐渐告别 "玄学"，变得更加 "科学"。 本文来自腾讯混元研究博客（HY Research），是继 《 从上下文学习远比我们想象的更难 》（Learning from context is harder than we thought）之后的第二篇公开研 究。在这篇文章里，混元团队将对大模型强化学习中的 "工程深水区" 展开探索，希望通过一系列提升 RLVR 训练细粒度可观测性的基础设施工具，降低 RLVR 底 层物理和统计机理研究的 "工程壁垒"。 这篇博客提出了异常梯度定位器（Gradient Anomaly Localizer, GradLoc），可以将全局梯度突刺（gradient spike）定位到具体出现问题的 token 上，助力系统性解决 强化学习中训练不稳定的问题，让开发者不再依赖直觉试错，而是基于确凿的数据证据进行 "确定性" 的算法迭代。 如果说 2024 年的大模型竞争焦点在预训练（Pre-training），那么 2025 年的主战场已彻底转向后训练阶段。通过利用数学、代码等领域的可验证结果作为反馈信号 （RLVR），大模型正在实现推理能力的显著跃升 ...

该图片可能由AI生成 前年写过腾讯会议是异地恋的核武器。 很多人觉得荒诞。 问我是不是对浪漫过敏？ 是会还没开够？是班还没上够？ 不不不。 用这种正儿八经的会议软件谈情说爱，不但不煞风景，反而最深情。 议题是你，议程是爱，时长不限，不愿掉线。 我不想让你活在我的碎片时间里，而是要你出现在我的主屏幕中央。 不是我闲了没事干了才来call你，我是专门为你腾出时间，调好光线，关掉通知，等你入会。 腾讯会议这四个字越严肃，越正式，就越证明，我在认真对待你。 为什么异地恋容易分手？ 因为大家缺乏信任。 远隔千里，一个怕自己成无能的丈夫，另一个怕自己拿了品如的剧本。 腾讯会议这种正式感，就是信任的锚点。 我连【想你】都要郑重其事发个会议，你能说我不在乎你？ 为什么？ 因为我在用对待重要事务的方式，对待你。 2 光在【名】上，腾讯会议这四个字带来的情绪价值，就已经锤爆其他app了。 那么，【实】呢？ 它直接把【物理上不在一起】这件事儿给稀释了，给弱化了。 1 （截图来自小红书） 腾讯会议可以共享屏幕，他打游戏你围观，你看综艺他陪笑。 节奏同步，情绪同频。 物理上，远隔千里。 体感上，同在一起。 哪怕网络有点波动，画面也不卡 ...
