xAI Deploys 100,000-GPU Supercomputer in 19 Days, Prompting "Superhuman" Praise and Elon Musk's AI Shift

Entrepreneur Mario Nawfal recently highlighted Nvidia CEO Jensen Huang's commendation of Elon Musk, stating that Musk and his xAI team achieved a "superhuman" feat by deploying a supercomputer with 100,000 Nvidia H100 GPUs in just 19 days. This rapid deployment, which industry experts suggest typically takes years of planning and execution, underscores the intense pace of innovation in the artificial intelligence sector. The tweet, shared on August 20, 2025, also drew a significant response from Elon Musk himself.

Musk, CEO of Tesla and xAI, acknowledged a personal shift in his approach to AI, stating, "I resisted AI for too long. Living in denial. Now it is game on." This remark signals a more aggressive stance from Musk, who has historically voiced concerns about the potential dangers of artificial intelligence, famously calling it humanity's "biggest existential threat" in the past. His company, xAI, launched in 2023, aims to "understand the true nature of the universe" and is positioned to compete with leading AI entities like OpenAI and Google DeepMind.

Jensen Huang's praise for Musk and xAI specifically highlighted the unprecedented speed of the supercomputer's construction, dubbed "Colossus," which is designed to train large language models at an immense scale. Huang emphasized the complexity of the undertaking, noting that such a project typically requires approximately three years for planning and an additional year for equipment delivery and operational setup. The successful installation of 100,000 H100 GPUs in less than three weeks showcases xAI's formidable engineering and logistical capabilities.

This development intensifies the competition within the AI landscape, as companies race to build more powerful models and the infrastructure to support them. Musk's renewed commitment to AI development, moving from caution to an aggressive competitive posture, sets the stage for a new phase of innovation. The rapid deployment of "Colossus" positions xAI as a significant player in the pursuit of artificial general intelligence (AGI), potentially accelerating advancements in the field.
