整理 | 褚杏娟 Sulaiman Ghori 在一期播客中，用了一个多小时详细讲述了他在 xAI 的经历。他说，在那里"从来没有人对我说不"，每个人都 被充分信任去做正确的事；只要是好想法，当天就能落地、当天就能得到反馈。他还提到，马斯克愿意被证明是错的，只要你 能拿出实验数据。 他也坦言，在上一家公司，很多事情也许他一个人能做得更快；但在 xAI，整体反而更快，因为几乎没有官僚流程。这些话， 听起来都是对公司的认同和马斯克的赞扬，实际上他还说自己是马斯克粉丝。 然后，播客发出来后第 3 天，他被解雇了。 外界猜测是因为他说了太多敏感信息。节目中，他透露了利用闲置特斯拉汽车驱动的人类模拟器 AI 代理的计划、还有马斯克 如何快速构建 Colossus 超级集群、xAI 在模型策略上的核心决策，曝光了公司内部部署测试的 AI 虚拟员工等，还有 xAI 也被 完全曝光。他坦率地谈到了激进的时间表、马斯克亲自参与的 Cybertruck 奖金计划、内部文化和运营方式以及一些非公开的 策略，这些言论引发了外界的强烈反响。 Sulaiman 自 2019 年起持续创业。在德国上大学一个月后退学，为了实现童年创办航天公 ...
