    全完了…… 我们又回来了!! (引用推文:Grok Bot 近来运行速度快得离谱,感觉就像 SpaceX 已经把 AI 数据中心送入了轨道。 说真的……这是怎么回事?! 它已经好得离谱了……)

    引用Teslaconomics@Teslaconomics

    Grok Bot is operating so insanely fast these days, it feels like SpaceX already launched AI data centers into orbit. Seriously… what is going on?! It’s gotten ridiculously good…

    开发者认为通过 CLI 使用编程智能体的方式已过时,交互正直接面向智能体展开。其当前方案结合 dots 这类高层持久智能体与 Codex desktop 专用会话,并由自建 agent orchestrator and harness 管理,可兼顾 Grok bot 的简单交互和 Codex desktop 的深度会话。

    引用Yuchen Jin@Yuchenj_UW

    I haven’t touched Claude Code or Codex CLI in a while. The terminal era is over imo. It's the wrong interface for coding agents. Tabs are ephemeral, but context is persistent, and managing 30 tabs is pure cognitive overhead. I don’t really need an IDE like Cursor either. I rarely navigate the whole codebase anymore. The new primitive is the agent, not the file. (Codex desktop app is the best agentic UI for now. But we’re still early.)

    xAI 上诉成功,美国第八巡回上诉法院暂时叫停明尼苏达州 AI 虚假裸照禁令

    美国第八巡回上诉法院应 xAI 请求颁布临时禁令,暂时搁置明尼苏达州反“脱衣伪造”法案,xAI 正主张该法违宪并限制受保护言论。该法于 8 月 1 日生效,禁止相关平台放任用户生成刻画可识别当事人私密身体部位的写实图像;明尼苏达州总检察长办公室对裁决表示失望,并将继续维护法律。xAI 称 Grok Imagine 已设置防护机制,并起诉绕过拦截未经许可制作他人性影像的用户。

    AWS 停止与政府签署数据中心项目保密协议,回应民众抵制

    AWS 首席执行官 Matt Garman 在官方博客中表示,公司已停止在新建数据中心审批中与各级政府机构签署保密协议,以回应外界对项目透明度的质疑。纽约已暂停大型数据中心审批一年,美国各地还有超过 100 项暂停审批提案正在审议。Garman 还回应了耗水、电价、排放和社区收益四类争议,并称过去三年亚马逊已向相关社区投入超过 10 亿美元。

    人形机器人是一种改变约束条件的资本品。它延长生产,并提高劳动力和土地的产出,这就是 Elon 所指的丰裕。 一个人每年提供约 2,000 小时。一周运行 168 小时的机器人可提供约 8,700 小时。他提出的 10 年内 10 亿台、价格在一万多美元的底线,相当于约 40 亿全职等价劳动力,而全球劳动力为 35 亿。 15 年时的 100 亿台则在此基础上再提高一个数量级。 机器人制造机器人仍需要储蓄,因为能源、材料和机器必须被竞价投入那条生产线。 预期中的丰裕适用于普通需求,而这对作为消费者的人们才是重要的。住房、食物、护理和常规医疗的价格将向能源和材料成本回落,直到家庭预算不再成为限制。 一个运营数百或数千台智能体的所有者获得该资本存量的回报,这也是全民高收入以购买力形式出现的方式。 货币价格仍是分配任何仍然稀缺之物的方式,即能源、地段、原材料。至少短期内如此。 能源是约束性投入,而在多个星球定居可增加单一世界之外的土地、矿产和发电能力。 简而言之:(1) 更多能源。(2) 多星球化没有坏处。 确实如此

    引用Rothmus 🏴@Rothmus

    A humanoid is a capital good on a scale that changes the constraint. It lengthens production and raises what labor and land can turn out, which is the abundance Elon is pointing at. A person supplies about 2,000 hours a year. A robot on a 168 hour week supplies about 8,700. His floor of 1 billion within 10 years, priced in the low 10,000s, equals about 4 billion full time equivalents against a world labor force of 3.5 billion. The 10 billion at 15 years is an order of magnitude past that. Robots building robots still require saving, because energy, materials, and machines have to be bid into that line. Expected abundance holds for ordinary wants which is what matters for people as consumers. Housing, food, care, and routine medicine get repriced toward energy and materials until a household’s budget stops being what limits them. An owner running 100s or 1,000s of agents earns the return on that capital stock, which is also how universal high income shows up as purchasing power. Money prices remain the way to allocate whatever is still scarce, that is energy, locations, raw materials. At least in the short term. Energy is the binding input, and settling more than one planet adds land, minerals, and generation beyond a single world. TLDR: (1) More energy. (2) Multiplanetary doesn’t hurt.

    pstack 0.15.9 发布新的 /correct skill,可在用户反复纠正智能体同类错误时识别模式,并通过架构、类型和检查修复问题。该版本还增强 /architect,加入设计智能体友好架构的说明,并新增基于 Brendan Gregg 基准测试清单的 /benchmark-checklist skill。

    引用lauren@poteto

    every time you intervene and correct your agent, you should think about how to eliminate it entirely. in order of value: 1. categorically eliminate the problem through better architecture or choice of data structures 2. turn it into a lint rule or test so CI catches it 3. turn it into a skill or rule 4. have humans review the code to catch it (ngmi)

    马斯克改口:特斯拉 AI5 芯片内存由 72GB 上调至 96GB

    马斯克表示特斯拉 AI5 芯片不再采用 72GB 内存,改为 96GB,以避免成为唯一使用该 LP5 最低内存配置的厂商。此前特斯拉曾因内存供货紧张将 AI5 内存减半、AI6 削减三分之一,当前 AI6 为 144GB LP6。AI5 已于四月份完成流片,用于自动驾驶和 Optimus 人形机器人,马斯克称其单芯片性能可对标 NVIDIA Hopper,能效可达对方三倍、整体成本约为百分之十。

    我们的 Grok Bot 才刚刚起步!团队所有人每天都在内部试用它,并用 bot 打造 bot,我希望这一点能体现出来。我们还有很多要改进、要发布的东西,但请期待 bot 会继续变得更好、更快、更强大。

    引用Morgan@morganlinton

    Okay, so after three days with Dot, I have to say, I am really impressed with it, but I do think Grok Bot is a better product at this stage. Will be sharing more details when I can, but I think a lot of people have missed how much Grok Bot has matured as a product since launch, and really how much you can do with it. I now honestly believe most people are really only scratching the surface most of the time with products in this category. And in most cases, if you just scratch the surface, most of the solutions seem kinda interchangeable. Once you go deeper, there start to be some very clear differences, and Grok Bot is the clear market leader at the moment in my opinion. Also, one major piece of alpha. If you want to really go deep with Grok Bot, and understand more about how you can really maximize what you can do with it, make sure to follow @poteto, and look back on her tweets over the last few weeks, some absolute gold in there. Bot on 🤘

    AI 让我感到悲伤

    一名具备技术背景的作者表达对 AI 发展的悲观情绪,认为 AI 创业、Codex 与 Claude 辅助编程意味着技艺、控制权和创造力的丧失,并批评 X 平台充斥 LLM 生成回复。作者同时认为 Twitter、LinkedIn 等机构只有约 20 年历史,重建并不困难,期待行业泡沫破裂后 AI 角色趋于稳定。

    超级智能(前称 AI)如今在会计测试中表现出色

    引用Andrew Curran@AndrewCurran_

    'More striking is how fast AI took the lead. Just eighteen months ago, the best AI models fell short of the average accountant’s ~37% score. Today, models ace those same tasks.' 'These results are provocative. So much so that we considered not publishing them for fear of misinterpretation. But we think transparency about the findings matters as people and institutions prepare for rapidly advancing AI.'

    Grok Bot 现在更主动了。 举例来说:用户改签航班后,它会注意到 Uber 预约未同步更新,并在转机途中提醒用户修改;用户借助 Starlink 网络在落地前完成更改,避免了麻烦。 Grok @Bot 是一款出色的助手。

    引用matt palmer@mattyp

    Grok Bot is now more proactive. What does that mean? Here's one example: I switched flights, but @bot noticed I didn't update my Uber reservation Bot realized, then pinged me to update the reservation *during* my connecting flight I had @starlink, so I was able to change it before I landed and save myself a headache

    AI 竞赛是一个科学-工业复合体

    AI 转型不仅是产业行为,更是政治、科学与意识形态共同驱动的科学-工业复合体,任何单一投资者、政客或团队都难以阻止。文中列举 Grok 4.7、Opus 5.5、GPT-6.1 Sol 等接连发布,以及美国 Stargate 和中国约 2 万亿元 AI 数据中心计划,说明政府、资本与科研正相互强化。
