What SpaceXAI is
SpaceXAI is SpaceX’s artificial-intelligence brand, formerly xAI, developing the Grok model family and related consumer and enterprise AI products. The official company page states its mission as “We build AI to understand the universe” (accelerating human scientific discovery), and the site footer reads “© 2026 SpaceXAI LLC”.
Company history
The timeline on the official company page records: xAI issued its company announcement on July 12, 2023; Grok-0 followed on August 18, 2023, Grok was announced on November 3, 2023, and Grok on X launched on December 7, 2023. In 2024 the company open-released Grok-1 and shipped Grok-1.5 and Grok-2; in 2025 it released Grok 3 and Grok 4 and established xAI for Government. On infrastructure, the official page notes the Colossus cluster was built with 200K GPUs in 122 days.
On February 2, 2026, SpaceX announced that it had acquired xAI — the official announcement page reads “SpaceX announced today that it has acquired xAI” — and the company now operates within SpaceX under the SpaceXAI name. This page does not go into the brand’s model details or product forms: the model family is covered in the Grok entry, and the agent product in the Grok Bot entry.
Current product entry points (Grok apps, API, console) are on the official website and in the developer documentation.
Discussion in the show
Both local episodes discuss the Grok product line of SpaceXAI (then xAI), but the discussions are about product experience rather than company history. In Weekly #001’s chapter “Grok Bot：为什么 Agent 需要一台永不下线的云电脑” (Chinese transcript), Yang Pan calls Grok Bot the future form in his view; in Weekly #002’s chapter “临时环境与常驻电脑的区别” (Chinese transcript), Guizang stresses that Grok Bot never shuts down and keeps its context (the paragraph). The full discussions of these experiences are covered in the Grok Bot entry and are not repeated here.
Frequently asked questions
What is xAI, and is it still called xAI?
