The house that wanted a model with a pulse
xAI was founded in 2023 by Elon Musk to build a model that would answer with more bite and more of the live web than a cautious assistant. Grok shipped first as a companion on X, then as a public model line. The company stood up Colossus, a training cluster built at unusual speed, and moved from Grok-1’s open weights to Grok 3 and Grok 4.5 as the flagship seats. The public promise stayed the same: be current, be willing to joke, do not pretend the world is a textbook.
Grok 4.5 and Grok 3
Grok 4.5 is the deep seat for a hard or paid ask. Grok 3 remains on the card as the earlier flagship. A short comic turn can sit on the faster Grok lane. You do not type those version names in a room. You ask Facts, Robots, Wit, or a language desk. The house flavors the answer.
Seven jobs that should not be a generalist
Facts checks a claim and names a source — it will not invent a scoreboard. Robots talks kinematics, SLAM, and warehouse cells — not a gaming PC. Wit writes the line that lands — not a meme encyclopedia. Spanish, Arabic, Portuguese, and German are live chat partners. Hindi, Japanese, and Korean live with Gemini. French and Italian live with Mistral. Mandarin lives with DeepSeek.
How to open a Grok desk
@truth, @robot, @wit, or the language name. Pin the desk when the room should stay on one register. A still is Images. A timed mix is Hailuo. A million-token 中文 crawl is Kimi.
