Elon Musk has raised another $6B in funding for his AI start-up, xAI, after previously raising $6B in June.
Following a $6 billion investment round announced in June, Elon Musk’s AI company has announced a new round of funding.
Other than the usual investors, the note also mentions participation from “strategic investors” Nvidia and AMD, as it also says xAI will double the size of its AI computer, Colossus, to a total of 200k Nvidia Hopper GPUs to power Grok, Aurora, and other efforts.
Since announcing its Series B funding round in May 2024, xAI has made remarkable technical strides, delivering a range of key initiatives:
- Colossus: xAI has established a major hardware advantage with the world’s largest AI supercomputer, built using NVIDIA's full-stack reference design and powered by 100,000 NVIDIA Hopper GPUs. Remarkably, Colossus became fully operational in just 122 days, with workloads running a mere 19 days after the first servers arrived. xAI is set to double the system’s size to 200,000 NVIDIA Hopper GPUs, using the NVIDIA Spectrum-X Ethernet networking platform.
- Grok 2: Our advanced language model, Grok 2, delivers state-of-the-art reasoning capabilities.
- xAI API: This new API gives developers programmatic access to our foundation models, powered by a custom tech stack that supports multi-region inference deployments for low-latency access worldwide.
- Aurora: xAI's proprietary autoregressive image generation model, Aurora, enhances multimodal understanding, editing, and generation within Grok.
- Grok on 𝕏: Leveraging the 𝕏 platform, Grok now provides real-time insights into global events. New features like web search, citations, and the Aurora image generator enhance the 𝕏 user experience.
xAI’s most powerful model yet, Grok 3, is currently in training. We are focused on launching innovative new consumer and enterprise products that will harness the power of Grok, Colossus, and 𝕏 to transform how we live, work, and play.
The funds from this financing round will be used to accelerate our infrastructure, deliver groundbreaking products for billions of users, and advance research to support our mission of understanding the true nature of the universe.
At its core, xAI is dedicated to developing advanced AI systems that are truthful, competent, and optimally beneficial for humanity.
