Hey Everyone,
While Nvidia has hit officially a $4 Trillion market cap, Elon Musk’s xAI launched their new frontier model Grok 4 on July 9, 2025. A frontier model just 28 months after xAI was founded.
I’m not a huge fan of the utility of LLM benchmarks, but according to artificial analysis.ai Grok 4 is indeed the smartest frontier model. For at least a few weeks.
xAI has made stunning progress in the 500 days since they released their first model.
From what we know Grok 4 has 1.7 trillion parameters with a hybrid architecture that has specialized modules for different cognitive tasks. It’s powered by xAI’s Colossus supercomputer with 200,000 Nvidia GPUs.
How to Access Grok 4
Grok 4 is now available through three main entry points: the X app, the xAI API, and the grok.com platform.
Evolution of Grok in a Nutshell
On Grok 4: “It’s a reasoning model where you can’t see the reasoning tokens or turn off reasoning mode.” – his first take.
Grok 4 describes the above image as: a “cute, bird-like creature (resembling a duck, chick, or stylized bird)”.
