With the potential to improve both space exploration and life on Earth, AI accelerates SpaceX's mission to make life multiplanetary, to understand the true nature of the universe, and to extend the light of consciousness to the stars. xAI, which was founded in 2023 and acquired by SpaceX in early 2026, is now an integral pillar of our vertically integrated company. We are rapidly constructing AI compute infrastructure—starting on Earth with the goal of extending to space—at industry-leading pace and cost efficiency. Our infrastructure supports training and inference for Grok, which has emerged as one of the world's most advanced frontier models. Grok is designed as a truth-seeking AI model, built on our founder Elon Musk's mission to enable humanity to understand the universe. We believe that accomplishing this mission requires a truth-seeking approach to AI. We define truth seeking as the active, relentless pursuit of what is objectively true about reality, and grounded in evidence, logic, empirical data, and first principles thinking. Our goal is to understand and explain what the universe appears to be doing, as accurately as current knowledge allows. Within two years of its initial model release, Grok achieved frontier-level performance in scientific reasoning, as measured by its GPQA Diamond score, an industry benchmark that evaluates AI models on a standardized set of questions written and validated by experts, on a faster timeline than reported by other leading model providers. Grok also benefits from integration with X, our real-time information, entertainment, and free speech platform, which serves as a foundational distribution and data engine for our AI ecosystem and further enhances Grok's truth-seeking objective.

人工智能既能帮我们探索太空，也能让地球上的人类生活得更好——所以它也是 SpaceX 完成使命的关键工具。
xAI 这家公司 2023 年成立，2026 年初被 SpaceX 收购，现在是我们"全程自己干"体系里很重要的一根柱子。我们正在以行业领先的速度和成本快速建造 AI 算力基础设施——先在地球上建，未来目标是把算力搬到太空中去。
这套基础设施主要用来训练和运行 Grok——Grok 是我们的旗舰 AI 模型，已经是世界最先进的"前沿模型"之一。Grok 的设计目标是做一个"专门追求真相"的 AI，它的使命来自我们的创始人 Elon Musk——让人类真正理解宇宙。**"追求真相"**这件事我们非常认真：它不是营销话术，而是说这个 AI 会主动、持续地去找"客观事实是什么"——靠证据、靠逻辑、靠实验数据、靠最基本的物理和数学原理（"第一性原理"）。我们的目标是：尽人类目前的知识所能，最准确地理解并解释宇宙正在做什么。
Grok 上线两年之内，在科学推理上达到了"前沿水平"——用业内公认的 GPQA Diamond 评测（让 AI 答专家写的高难度科学题）来衡量，比其他主流大模型厂家公布的进度更快。Grok 还接入了 X（一个实时信息、娱乐和言论自由平台），让 Grok 既能拿到最新数据，也能分发到全球用户那里——这让 Grok "追求真相"的目标更有抓手。

把算力基建从地球延伸到太空这个愿景太震撼了，如果真的实现，太空探索和AI训练都会迎来质变。Grok用两年在科学推理上追平甚至超越其他前沿模型，这种“追真相”的路径确实比单纯拼参数更有意义。好奇未来xAI在星链或火星基地的算力部署上有什么具体时间表？
招股书里把Grok定位为“追求真相”的AI，这确实和市面上大多数迎合流量的模型很不一样。但有个好奇的地方：当“真相”和X平台上的实时信息、言论自由之间出现冲突时，Grok会怎么裁决？是靠第一性原理硬推，还是会有某种权重机制？另外，未来算力上太空这个构想很震撼，但太空环境对散热和能耗的要求完全不同，SpaceX目前有具体的技术路线图吗？
这种把AI算力从地球延伸到太空的构想确实震撼，如果Grok真的能基于第一性原理在宇宙尺度上追求“客观真相”，那不仅是技术突破，更是人类认知边界的拓展。好奇的是，未来在太空中训练AI，数据传输和能耗问题如何解决？
“追求真相”这个定位很有意思，尤其是结合Grok接入X实时数据这一点，确实比其他封闭训练的大模型更有潜力去验证和迭代事实。不过，把算力扩展到太空这个目标很震撼，但实际落地会面临散热、辐射和能源供应这些硬挑战，不知道招股书里有没提具体的时间表或技术路径？另外好奇Grok在科学推理上的GPQA得分具体是多少，方便和同行对比一下差距。”
