xAI’s progress is accelerating rapidly.

We have closed our Series C funding round of $6 billion with participation from key investors including A16Z, Blackrock, Fidelity Management&Research Company, Kingdom Holdings, Lightspeed, MGX, Morgan Stanley, OIA, QIA, Sequoia Capital, Valor Equity Partners and Vy Capital, amongst others. Strategic investors NVIDIA and AMD also participated and continue to support xAI in rapidly scaling our infrastructure.

Since the announcement of the Series B in May 2024, xAI has made significant technical progress and shipped a multitude of key initiatives including:

• Colossus, xAI has established a decisive hardware advantage with the world's largest AI supercomputer using an NVIDIA full stack reference design with 100,000 NVIDIA Hopper GPUs. Compared to typical multi-year industry timeframes, Colossus was fully operational in 122 days and started running workloads just 19 days after the first servers were delivered. Soon, xAI will double the size of Colossus to a combined total of 200,000 NVIDIA Hopper GPUs, achieved by using the NVIDIA Spectrum-X Ethernet networking platform.
• Grok 2, our frontier language model with state-of-the-art reasoning capabilities
• xAI API, gives developers programmatic access to our foundation models and is built on a new bespoke tech stack that allows multi-region inference deployments for low-latency access across the world.
• Aurora, xAI’s proprietary autoregressive image generation model for Grok enhances multimodal understanding, editing, and generation capabilities
• Grok on 𝕏, leveraging the 𝕏 platform to understand what's happening in the world in real-time. We recently added new features enhancing the 𝕏 experience like web search, citations, and our recent image generator, Aurora

xAI’s most powerful model yet, Grok 3, is currently training and we are now focused on launching innovative new consumer and enterprise products that will leverage the power of Grok, Colossus, and X to transform the way we live, work, and play.

The funds from this financing round will be used to further accelerate our advanced infrastructure, ship groundbreaking products that will be used by billions of people, and accelerate the research and development of future technologies enabling the company’s mission to understand the true nature of the universe.

xAI is primarily focused on the development of advanced AI systems that are truthful, competent, and maximally beneficial for all of humanity.

xAI is hiring aggressively and seeks mission-oriented individuals ready to join an elite team with the highest talent density focused on making a transformational impact on the future of humanity. Those interested can apply today at x.ai/careers.
