2025 was a year of breakthrough momentum, where the xAI team advanced a multitude of key initiatives including:
- Data Centers: xAI continues to expand its decisive compute advantage with the world’s largest AI supercomputers at Colossus I and II, ending the year with over one million H100 GPU equivalents.
- Grok 4 Series: our frontier language models are built on the best-in-class training infrastructure powered by Colossus. xAI has pushed reinforcement learning training to unprecedented levels, refining Grok’s intelligence, reasoning, and agency using pretraining-scale compute.
- Grok Voice: the most intelligent voice agent driving real-time conversations in voice mode and available via agent API. Grok Voice delivers low-latency speech in dozens of languages, tool calling, and real-time data access, serving millions of users across the Grok mobile app and in Tesla vehicles.
- User metrics: our reach spans approximately 600 million monthly active users across the 𝕏 and Grok apps.
- Grok Imagine: our lightning-fast image and video generation models that brings state-of-the-art multimodal understanding, editing, and generation capabilities.
- Grok on 𝕏: leveraging the 𝕏 platform to understand what’s happening in the world in real-time, utilizing xAI’s most powerful model to date.
Looking ahead, Grok 5 is currently in training, and it is focused on launching innovative new consumer and enterprise products that harness the power of Grok, Colossus, and 𝕏 to transform how we live, work, and play.
This financing will accelerate our world-leading infrastructure buildout, enable the rapid development and deployment of transformative AI products reaching billions of users, and fuel ground-breaking research advancing xAI’s core mission: Understanding the Universe.
