xAI has announced the successful completion of its Series B funding round, raising $6 billion with contributions from prominent investors including Valor Equity Partners, Vy Capital, Andreessen Horowitz, Sequoia Capital, Fidelity Management & Research Company, Prince Alwaleed Bin Talal, and Kingdom Holding, among others.

$6 billion in a single venture round is an enormous sum. However, OpenAI CEO Sam Altman has been discussing efforts to raise trillions to build the chip-making infrastructure needed for advanced AI.

The official announcement said that the company has made significant progress since its launch in July 2023. In November, xAI released its Grok-1 model on X, followed by the recent introduction of the improved Grok-1.5 model, which features long context capabilities. Additionally, the Grok-1.5V model now includes image understanding, marking a significant enhancement in the company’s AI capabilities. The open-source release of Grok-1 has paved the way for various advancements, optimizations, and extensions in AI applications.

Looking ahead, xAI plans to maintain its rapid pace of development, with several exciting technology updates and product launches expected in the coming months. The newly raised funds will be utilized to bring xAI’s first products to market, build advanced infrastructure, and accelerate research and development of future technologies.

This substantial investment will support xAI’s mission to develop advanced AI systems that are truthful, competent, and beneficial for all of humanity, while also striving to understand the true nature of the universe.

Musk parted ways with the other co-founders of OpenAI long ago, but his AI startup, xAI, is borrowing OpenAI’s strategy of building larger models to achieve greater intelligence. This approach has proven successful so far, with OpenAI delivering impressive demos and anticipating further advances with its next big model, GPT-5, by year’s end.

There’s no guarantee that this progress will continue. Musk is known for tackling giant missions and delivering results, as seen with Tesla and SpaceX. However, his history is also marked by failures, particularly with software projects like Tesla’s autonomous-driving features and his efforts to revitalize Twitter under its new name, X.

Only a few existing companies – possibly Google, Meta, and Anthropic – are seriously competing with OpenAI in developing the largest language models, known as frontier models. These competitors have been in the game for years, while xAI is less than a year old. Hiring AI talent is currently very expensive, and the advanced AI chips needed are costly and scarce.

Rumors around the deal:

According to The Information, cited by Axios,  xAI plans to build a massive new supercomputer, dubbed the “Gigafactory of compute,” potentially in partnership with Oracle. Such a project could deplete this investment round before it even goes online.

Musk intends to use the real-time access to X’s data to help xAI create a more news-savvy chatbot, but there’s also a risk of recycling extremist misinformation. This is supported by the fact that he often blurs the lines between the companies he owns.

Some observers, including OpenAI in its defense against a lawsuit from Musk, suggest that Musk envies OpenAI’s success with ChatGPT and is building xAI to reclaim the spotlight. Musk and his supporters argue that OpenAI and Google are endangering AI’s future by implementing guardrails against hate speech. Pro-guardrail advocates believe these measures prevent chatbots from making horrifying statements, but Musk criticizes them as “woke” and “deadly” forms of lying.
