We were told it would take 24 months to build. So we took the project into our own hands, questioned everything, removed whatever was unnecessary, and accomplished our goal in four months. We doubled our compute at an unprecedented rate, with a roadmap to 1M GPUs. Progress in AI is driven by compute and no one has come close to building at this magnitude and speed. 200K GPUs 194 Petabytes/s 3.6 Terabits/s >1 Exabyte We’re moving toward a future where we will harness our cluster’s full power to solve intractable problems. What’s one seemingly impossible question you’d answer for humanity? Running jobs with 150K+ GPUs and 99% uptime Grok 4 is the most intelligent model in the world. It includes native tool use and real-time search integration, and is available now to SuperGrok and Premium+ subscribers, as well as through the xAI API. We are also introducing a new SuperGrok Heavy tier with access to Grok 4 Heavy - the most powerful version of Grok 4. We are excited to announce Grok For Go
