xAI completed its 100,000 Nvidia H100 AI data center before Meta and OpenAI despite the Meta and OpenAI getting chips delivered first. xAi completed the main chip installation and build in 19 days and the overall project in 122 days. Nvidia CEO Jensen Huang says this scale of build can take a year for many companies. The time xAI has saved has already allowed it to catch up for Grok 3 to be trained and ready by the time GPT5 is release and before Llama 4 is released.
