Elon Musk’s AI company, xAI, has just launched the Colossus, now the world’s most powerful AI training system. The Colossus, featuring a staggering 100,000 H100 training cluster, sets a new standard in the rapidly evolving AI world. This cluster is expected to double in size soon, reaching a remarkable 200,000 units.
Musk, the owner of X, a social media platform, announced the news on September 2. He revealed that his xAI team took 122 days to get Colossus up and running. This development puts Musk at the forefront of the race to create the most advanced AI systems.
Colossus: A Game-Changer in AI Training
The Colossus is now considered the most powerful AI training system available, thanks to its massive number of graphics processing units (GPUs). One user on X highlighted how this new system surpasses every major AI model developed so far. To put this in perspective, OpenAI’s most advanced model uses 80,000 GPUs, far fewer than the Colossus.
This groundbreaking AI model was created in collaboration with Nvidia, the top semiconductor chip manufacturer in the world. Nvidia’s H200 chip, known for its high performance, was previously one of the most sought-after chips in the market. However, it has recently been overshadowed by Nvidia’s latest Blackwell chip, introduced in March 2024.
Comparatively, the H200 chip comes with 141 gigabytes of HBM3E memory and a bandwidth of 4.8 terabytes per second. Nvidia’s Blackwell chip boasts a 36.2% higher top-end capacity and 66.7% more total bandwidth than the H200.
Following the launch of Colossus, Nvidia congratulated Musk and the xAI team. They praised the system for its unmatched power and impressive energy efficiency.
The AI community has widely celebrated this achievement, with many industry professionals calling it a significant milestone. Cathie Wood, CEO of ARK Invest, also commended the team, describing the launch as “impressive” and hinting at more big news to come.
A New Era of AI Development
Back in April 2023, reports emerged of Musk purchasing a large number of GPUs, with some sources suggesting he bought nearly 10,000 units for his xAI projects. Musk has been open about his ambitions in AI development, aiming to build a supercomputer by fall 2025 and potentially partnering with Oracle.
While pushing the boundaries in AI, Musk has also supported the idea of regulating this technology. On August 27, he expressed his support for California’s Senate Bill 1047, which calls for stricter AI regulations. Although some in the tech industry fear that such laws could hinder innovation, Musk has long advocated for AI oversight, comparing it to regulations for any potentially risky technology.
Moreover, on August 9, Musk’s platform X agreed to halt processing personal data for users in the European Union. This decision followed legal action from the Irish Data Protection Commission.
As xAI continues to expand and innovate, Musk’s influence on the AI sector shows no signs of slowing down. The launch of Colossus marks a significant leap forward, not just for Musk, but for the future of AI as a whole.
