André Garreta

I joined xAI to manifest AI’s acceleration of scientific discovery. With the release of Grok 4, I now feel we have the foundation upon which we can Understand the Universe. The techniques that brought you Grok 4 will compound the next scaling paradigms, and humanity’s scientific and artistic endeavors will feel the inexorable leverage of AI. To my friends and colleagues at xAI, it is the professional honor of a lifetime to work alongside you - I am ever grateful for your tenacity, mentorship, and brilliance. Not a day has gone by that I haven’t pushed my limits, solved interesting problems, and laughed my head off :) Time dilation here is real; I live lifetimes every day. To everyone on X, this revolution is still in its infancy, and Grok 4 is the edge of the event horizon. If you want to chart a path into the unknown, etch your name in the stars, and charge into the singularity, join us. Ad astra, per aspera!
