Grok 4 Is Finally Here

Here's everything you need to know about Grok 4. Key features, benchmarks, pricing, API access, and Elon Musk's future plans.

Elon Musk and xAI have officially launched Grok 4, their most powerful AI model yet. The announcement was made during a one-hour livestream event on the X platform, where Musk gave a full walkthrough of what the new model can do.

The new model is set to compete with Google’s Gemini 2.5 Pro and OpenAI’s upcoming GPT-5 model, which is expected to be launched later this summer. The new model is trained on xAI’s Colossus supercomputer for advanced, scientist-grade reasoning. It has 100 times more training data than Grok 2 and 10 times more reinforcement learning compute than any other model available.

During the stream, Elon said, “With respect to academic questions, Grok 4 is better than PhD level in every subject, no exceptions.” He also mentioned that we’re entering a new era in AI, something he called “Big Bang Intelligence.”
