SpaceX is reportedly in talks to merge with xAI
SpaceX + xAI + Tesla 的横向整合正在成形:火箭提供发射能力,轨道卫星提供算力基础设施,xAI 提供模型,Tesla 提供边缘终端。如果三家合并,将是有史以来垂直整合程度最高的 AI 基础设施帝国——从能源(太阳能卫星)到算力(轨道数据中心)到模型(Grok)到终端(Tesla)全打通。

6.4 billion from operations on just 3.2 billion
xAI 单位经济极差:亏损是营收的 2 倍。同期 Anthropic 接近盈利、营收增 130% 至 $109 亿——xAI 落后竞争对手一整代。
orbital AI compute satellites as early as 2028
首个正式时间表:2028 年开始部署轨道 AI 计算卫星——Musk 把 SpaceX 卫星制造能力作为 AI 算力竞争的差异化武器。
multiple trillions of parameters
xAI 下一代模型目标「数万亿参数」——首次有头部 AI 公司在 SEC 文件中正式承诺这一规模,行业 scaling 战仍未结束。
SpaceX 'bought' xAI for 250 billion USD. xAI previously 'bought' Twitter in March 2025. SpaceX is expected to go public this or next year. Iow, Musk is combining everything to a) inflate overall value b) externalise all risks to investors c) get his biggest payday yet
Grok will be live tweeting nudified astro-pics from every launch and starlink satellite burning up in the atmosphere

An “attention map” of each prediction shows the important data points considered by the models as they make that prediction.
This gets us closer to explainable AI, in that the model is showing the clinician which variables were important in informing the prediction.
Koo's discovery makes it possible to peek inside the black box and identify some key features that lead to the computer's decision-making process.
Moving towards "explainable AI".
