xAI is making rapid progress in developing advanced AI technology.
The company, launched in 2023 as a rival to OpenAI and Anthropic, raised the cash from investors including Valor Equity Partners, NVIDIA, and Qatar Investment Authority.
Funds will expand massive compute clusters like Colossus, train Grok 5, and launch new tools with 600 million monthly users across X and Grok apps.
Elon Musk celebrated the milestone on X, highlighting 2025 goals such as superclusters with over one million GPUs and advanced voice agents in Tesla vehicles.
2025 was a year of big progress for xAI.
The team made advances in many important areas. Learn more at Aios.blog.
Data Centers: xAI kept growing its lead in computing power. It has the world’s largest AI supercomputers at Colossus I and II. By the end of the year, they had more than one million H100 GPU equivalents.
Grok 4 Series: These are xAi’s top language models. They are built on the best training setup powered by Colossus. xAI took reinforcement learning to new heights. This improved Grok’s smarts, thinking skills, and ability to act.
Grok Voice: This is the smartest voice agent. It handles real-time talks in voice mode and through an API. Grok Voice offers quick speech in many languages, calls tools, and gets real-time data. It serves millions of users in the Grok mobile app and in Tesla cars.
User metrics: They reach about 600 million active users each month across the X and Grok apps.
Grok Imagine: These are their super-fast models for making images and videos. They bring the latest in understanding, editing, and creating content with multiple types of media.
Grok on X: It uses the X platform to know what is happening in the world right now. It runs on xAI’s most powerful model so far.
Looking forward, Grok 5 is in training now.
The team is focusing on launching new products for consumers and businesses.
These will use the power of Grok, Colossus, and X to change how we live, work, and have fun.
This funding will speed up their top infrastructure growth and help them build and launch game-changing AI products for billions of users.
It will also support key research to advance xAI’s main goal: Understanding the Universe.
