AI大模型之争最后拼的是成本,谁更有钱,谁成本能做到最低,谁就赢。 赢家就这么几个: DeepSeek:有钱、沉默猛攻AGI中 Gemini+豆包:有钱、 有用户、有卡 Grok:超有钱、有用户、有流量 Gpt/claude:应该能行 其他应该都挺难的,股价可能崩盘,融资终究撑不到AGI,成本降不下来、钱会烧光等等

AI 大模型的训练方式,不就是中式教育吗? 预训练:填鸭式硬灌。 不管模型懂不懂,先把全网的语料一股脑塞进参数里。 就像我们小学背课文、中学背元素周期表。那时候你懂吗?你也不懂啊,先背下来再说。 数据标注:做题、对答案。 标注员就相当于参考答案,给每道题标上标准解。 模型的任务,就是疯狂刷这些已经标好答案的题,直到输出越来越接近正确答案。 监督微调:专项补习,一对一辅导。 担心你高分低能,就再给你请个家教,针对性补课。 RLHF:基于人类反馈的强化学习。 你不光得学会答题,还得当个三好学生;不光答案要对,还得让家长和老师觉得你态度端正、说话好听。 结果现在的 AI,一个个全是讨好型人格。 说的就是你们几个佞臣:豆包、Gemini、ChatGPT。 过拟合:历年真题能考满分,一换新题就傻眼。 刷了三千套卷子,结果遇到一道没做过的应用题,当场就崩了。 梯度下降:纯纯的错一罚十。 每次答错,系统就根据误差反向调整权重。 这不就是错题本吗?哪道题错了,罚你抄十遍,直到下次不再犯。 注意力机制:老师划重点。 几千字的上下文,模型只盯着其中几句关键的 Token,其他内容全当背景。 整本书都是白的,只有荧光笔标黄的那几句算重点。 灾难性遗忘:考完一科扔一科。 刚学完新的数学知识,之前学的语文可能就忘了。新知识一覆盖,旧知识就开始往外掉。 上下文窗口。 嗯,跟你脑子一样,容量就那么大。前面说得太多,后面的就记不住了。 涌现能力:突然开窍的幻觉。 参数规模超过某个临界点后,模型突然会写诗、会推理了。 老师管这叫“开窍了”,AI 圈管这叫“涌现”。 但你也不知道,它到底是真的懂了,还是题刷得太多,刚好把规律背下来了。

This is an email I sent earlier today to all employees at Coinbase: Team, Today I’ve made the difficult decision to reduce the size of Coinbase by ~14%. I want to walk you through why we're doing this now, what it means for those affected, and how this positions us for the future. Why now Two forces are converging at the same time. We need to be front footed to respond to both. First, the market. Coinbase is well-capitalized, has diversified revenue streams, and is well-positioned to weather any storm. Crypto is also on the verge of the next wave of adoption, with stablecoins, prediction markets, tokenization, and more taking off. However, our business is still volatile from quarter to quarter. While we've managed through that cyclicality many times before and come out stronger on the other side, we’re currently in a down market and need to adjust our cost structure now so that we emerge from this period leaner, faster, and more efficient for our next phase of growth. Second, AI is changing how we work. Over the past year, I’ve watched engineers use AI to ship in days what used to take a team weeks. Non-technical teams are now shipping production code and many of our workflows are being automated. The pace of what's possible with a small, focused team has changed dramatically, and it's accelerating every day. All of this has led us to an inflection point, not just for Coinbase, but for every company. The biggest risk now is not taking action. We are adjusting early and deliberately to rebuild Coinbase to be lean, fast, and AI-native. We need to return to the speed and focus of our startup founding, with AI at our core. What this means To get there, we are not just reducing headcount and cutting costs, we’re fundamentally changing how we operate: rebuilding Coinbase as an intelligence, with humans around the edge aligning it. What does this mean in practice? - Fewer layers, faster decisions: We are flattening our org structure to 5 layers max below CEO/COO. Layers slow things down and create coordination tax. The future is small, high context teams that can move quickly. Leaders will own much more, with as many as 15+ direct reports. Fewer layers also means a leaner cost structure that is built to perform through all market cycles. - No pure managers: Every leader at Coinbase must also be a strong and active individual contributor. Managers should be like player-coaches, getting their hands dirty alongside their teams. - AI-native pods: We’ll be concentrating around AI-native talent who can manage fleets of agents to drive outsized impact. We’ll also be experimenting with reduced pod sizes, including “one person teams” with engineers, designers, and product managers all in one role. In short: AI is bringing a profound shift in how companies operate, and we’re reshaping Coinbase to lead in this new era. This is a new way of working, and we need to leverage AI across every facet of our jobs. To those who are affected I know there are real people behind these decisions — talented colleagues who have poured themselves into this company and our mission. To those of you who will be leaving: thank you. You’ve helped build Coinbase into what it is today, and I am sincerely grateful for everything you've done. All impacted team members will receive an email to their personal account in the next hour with more information, and an invitation to meet with an HRBP and a senior leader in your organization. Coinbase system access has been removed today. I know this feels sudden and harsh, but it is the only responsible choice given our duty to protect customer information. To those affected, we will be providing a comprehensive package to support you through this transition. US employees will receive a minimum of 16 weeks base pay (plus 2 weeks per year worked), their next equity vest, and 6 months of COBRA. Employees on a work visa will get extra transition support. Those outside of the US will receive similar support, based on local factors and subject to any consultation requirements. Coinbase prides itself on talent density. Our employees are among the most talented people in the world, and I have no doubt that your skills and experience will be highly sought after as you pursue your next chapters. How we move forward To the team that is staying, I know this is a difficult day. We’re saying goodbye to colleagues and friends you've been in the trenches with. But here’s what I want you to know as we move forward together: Over the past 13 years, we have weathered four crypto winters, gone public, and built the most trusted platform in our industry. We’ve made it this far by making hard decisions and by always staying focused on our mission. This time will be no different – nothing has changed about the long term outlook of our company or industry. And most importantly, our mission has never been more important for the world. Increasing economic freedom requires a new financial system, and we’re building it. The Coinbase that emerges from this will be more capable than ever to achieve our mission. Brian

港股AI大模型双雄近期集体跳水,智谱一度跌破1,000港元,MiniMax一度跌破200港元。 想当年智谱顶着 大模型第一股 上市,市值一度冲到近1.4万亿港元,如今随着逐渐解锁,两家加起来较巅峰蒸发超7,000亿。 这不就是VC币解锁的翻版?一级估值吹上天,二级散户高位接盘,锁仓期一过,早期机构含泪套现离场。 果然炒股/币都是换汤不换药,美股有 $SPCX ,币圈有VC,港股有双雄。 不过有一说一,双雄这个价格,挺诱人的,扶我起来,我想抄底了!

港股 AI 大模型走势分化,中国版 OpenAI (minimax)和 Anthropic (智谱)正在走向两条路,一个股价腰斩,一个一周翻倍再创新高。 恒生科技杀猪盘最近跌得惨不忍睹,互联网板块几乎全军覆没,唯独 AI 大模型赛道逆势走强,而且内部也开始分化了。 两家公司正在走向完全不同的路径。智谱是中国的 Anthropic,MiniMax 是中国的 OpenAI。 智谱(02513)走的是 Anthropic 路线,死磕编程能力和 B 端部署。GLM-5.2 在 Code Arena 前端榜排名第二,实际能力和 Opus 4.6 差不多,挤进编程领域世界前三。6 月 13 日智谱把 GLM-5.2 以 MIT 协议全量开源、支持百万 token 上下文,市场直接把它定义成"闭源前沿模型受限后的国产承接方"。股价 6 月 22 日盘中触及 HK$2,960,市值短暂破兆,较 1 月发行价 116.2 港元涨了近 30倍。 MiniMax(00100)则是 OpenAI 的路子,主攻 C 端市场和多模态。产品形态更偏向消费级应用,有海外收入和用户。近一个交易日虽涨了约 12% 报 HK$498,但距离 3 月 HK$1,330 的历史高点还差得远,目前只是低位反弹。一个创新高、一个在底部挣扎,两家公司的差距正在拉大。 主要原因是 7 月初两家公司的基石投资开始解锁,minimax 的解锁比例较大,一次增加了 3 倍的供给。智谱的解锁压力较小,同时正准备转往中国大陆上市。 现在要用 U 来买港股, @StableStock 做的不错,币圈其他交易所暂时没有支持港股交易,后续stablestock还会再上其他股票市场,比如日本、韩国、台湾等。现在他们新上了一个港股杠杆交易功能,2 倍杠杆买 10,000 USDT 的现货只需约 5,000 USDT 保证金,3 倍约需 3,333 USDT,大幅降低进场门槛。而且日内开平不计息,持仓成本比合约低,但港股手续费会比较贵不好做频繁交易。杠杆持仓日内不计息,但留仓过夜会计息。 恒生科技这轮调整,传统互联网股票基本没有幸免,资金全部涌向 AI 大模型。智谱的市值更是超过了一众老登股,小米、美团、京东、百度等确实有点离谱了,主要原因也是流通股较少,和币圈的高 FDV 低流通有点类似,一旦有大额解锁才是真正验证的时候,毕竟基石投资者几十上百倍收益很难不抛售。
