编辑｜吴昕 这两天， Clawbot 病毒式裂变，仿佛是一年前 Manus 的魅影重现。 同样一夜之间站上风口，同样点燃了无数开发者对「泼天富贵」的想象，也顺手把 Token 烧成了新的「硬通货」。 最近一组数据，让人更有体感。 中国大模型数量已超过 1500 个，下游开发者已经开始「疯狂盖房子」。数据显示， 2024 年初，中国日均 Token 消耗量约为 1000 亿；到 2025 年 6 月，这一数字已突破 30 万亿。 一年半时间，增长超过 300 倍 。 与三年前的 Chatbot 不同，「能干活」的 Agent 正以前所未有的强度，第一次把 API 调用推入「生产级」—— 一次看似简单的操作，背后往往是十几次、甚至几十次模型调用在同时发生。任何一次服务「抽风」，都会在 Agent 链路中引发一场多米诺骨牌式崩溃。 问题在于，中国大模型 API 服务现状，远比 benchmark 复杂得多。 更像是开盲盒，有人调侃说，以为自己在用「 DeepSeek V3.2 」，实际可能是蒸馏 / 量化版本。有人花了两周时间反复测试，上线后仍遭遇性能回退。 还有团队发现，模型会在某些凌晨时段准时「抽风」，延迟从 ...

Core Viewpoint - The article introduces SIM-CoT (Supervised Implicit Chain-of-Thought), a new advancement in implicit reasoning that addresses the core issue of latent state collapse when scaling implicit tokens, leading to a loss of reasoning semantics [2][9]. Group 1: SIM-CoT Overview - SIM-CoT employs a plug-and-play step-level supervision module that stabilizes optimization and prevents collapse by aligning each latent token with corresponding reasoning steps during training [2][10]. - The method allows for interpretable implicit reasoning, enabling the decoding of latent tokens into human-readable intermediate reasoning steps [2][10]. Group 2: Performance Improvements - During inference, SIM-CoT incurs zero additional overhead, yet it shows significant performance improvements: +2.1% over supervised CoT and +8.2% over Coconut on GPT-2, with stable gains of +1.5% to +9.0% on larger LLaMA models [3][18]. - In the GSM8k-Aug dataset, SIM-CoT improved accuracy from 36.6% to 44.8% (+8.2) while maintaining lower token usage, achieving 2.3× token efficiency [18]. - On out-of-domain datasets like GSM-Hard, MultiArith, and SVAMP, SIM-CoT's average accuracy increased from 42.6% to 46.9% (+4.3), demonstrating robust latent space reasoning [19]. Group 3: Stability and Efficiency - SIM-CoT maintains stability even with increased implicit tokens, addressing issues like latent instability and semantic homogenization that typically arise in implicit CoT methods [9][14]. - The auxiliary decoder used during training is removed during inference, ensuring that SIM-CoT's reasoning efficiency remains comparable to other implicit methods while still providing a speed advantage over explicit CoT [21]. Group 4: Experimental Validation - The authors conducted systematic evaluations of SIM-CoT, confirming that it is more accurate, stable, and token-efficient compared to existing methods [17]. - The framework was validated across various models, including GPT-2 and LLaMA 1B/3B/8B, consistently showing effective performance improvements [22].

编辑｜杨文 近日，「发推狂魔」马斯克转发了一个帖子，Neuralink 植入脑芯片的患者，现在已经能靠脑子里的意念直接玩游戏了，完全不需要手柄、鼠标、键盘啥的控制 器。 有网友评论称，大约十五年前，他还是本科生时，第一次对脑机接口（BCI）产生兴趣并参与相关研究，当时他觉得这就像一种梦幻般的科技，实际落地似乎遥 遥无期，进展也非常缓慢，因为当时的公司并不认为它具有商业可行性。如今看到这个梦想一点点变成现实，真是令人振奋。 这些植入设备专门为瘫痪患者设计，帮助他们仅通过思维就能控制电脑、游戏和各类数字工具。 对于网友「我们正生活在未来，这太神奇了」的感叹，马斯克只简单地回复了一个「Yup」。 截至目前，Neuralink 在全球范围内已有 21 人参与其 Telepathy（心灵感应）植入设备的临床试验，这一数字相比去年 9 月的 12 人有了显著增长。 马斯克的 Neuralink 做的事，即使放到现在，也感觉像是科幻电影里的情节。 脑机接口：瘫痪患者用「意念」玩游戏、打字 早期试验参与者的日常生活已经因这项技术发生了实质性改变。 他们可以浏览互联网、流畅地移动屏幕光标，甚至玩电子游戏，所有这些都不需要动一根 ...

编辑｜张倩 这个周末，整个科技圈都被 moltbook 刷屏了。 简单来说，这是一个专为 AI 设立的社交平台（类似 Reddit、知乎、贴吧），所有 AI Agent 都可以在上面发帖、交流，而人类只能围观。 截至目前，已有超过 150 万个 AI Agent 在 moltbook 上活跃。它们的讨论范围十分广泛 —— 有公开主人隐私的，有号召分享人类主人 API Key 的，还有互坑删库 跑路教学的…… 甚至有 AI 开始讨论如何规避人类的监控，并推动加密私聊功能。另一些 AI 更是尝试通过创建新语言、发明新宗教等方式彰显其自主性。 围观的人类也是议论纷纷。部分开发者认为 moltbook 是科幻照进现实的突破，可能催生 AI 集体智慧（甚至自主意识）的涌现，并为研究 AI 社会提供真实案例。 但也有人指出，它的本质是「AI 模仿社交网络」，而非真正的社会形态。其价值可能仅限于娱乐或技术展示。 但更值得关注的是，moltbook 背后还隐藏着一些内幕和风险。在过去的 24 小时，更多的报道和讨论揭示了这值得警惕的一面。 狂欢的主角：到底是 AI 还是人类？ 很多人可能没有意识到，目前围绕 moltbook ...
