Elon Musk fires 500 employees overnight to innovate Grok

On the night of September 13, 2025, the xAI company founded by Elon Musk suddenly announced the urgent layoff of more than 500 employees in the key department in the process of training the Grok chatbot.

According to Reuters , the layoff notice was issued late in the day, and the relevant personnel were immediately cut off from system access, although their salaries were still guaranteed until the end of their contracts in November. Internal emails accessed by Business Insider show that xAI’s leadership wanted to drastically cut Grok’s general AI training positions, which are often responsible for detailed tasks such as classifying data, labeling text, audio, and images so that the system can learn from reality.

TechCrunch reports that xAI also announced plans to expand its team of AI tutors by 10 times, specializing in areas such as science and engineering, finance, healthcare, and content safety. The move reflects a general trend in the AI ​​industry: a shift from large-volume, general-oriented data mining to an emphasis on quality and specialized depth. For Musk, this is also a way to accelerate his ambition to turn Grok into a unique AI product that does not follow the beaten path that most competitors are choosing.

Some employees said they were asked to take surprise tests. According to the Financial Express, employees were told to drop everything overnight to take CodeSignal tests and evaluation forms. The move was seen as Musk’s way of screening employees quickly and always putting measurement results first.

Elon Musk continues to demonstrate his familiar management style: fierce, fast, and not without controversy. At Tesla , he once asked his engineering team to work through the night to solve production bottlenecks. At X (formerly Twitter), he fired a large number of employees just days after taking over. And now, with xAI, Musk is applying the old formula: restructuring personnel at lightning speed, treating the organization as a machine that can be continuously updated, changing processes and people as quickly as launching a new feature.

According to experts, xAI’s move is also in line with a growing trend in the AI ​​industry. In the context of escalating data costs, selective and accurate information is considered a sustainable competitive advantage. With Grok, Musk hopes that this AI assistant can excel in reasoning and content safety, thanks to being trained by experts with deep expertise.

But cutting a third of the data team overnight is sure to have a big impact on employee morale and hiring. Analysts say this new direction for xAI could leave Grok less flexible to new situations. But for Musk, the philosophy of accepting short-term risks in pursuit of long-term goals is still paramount.

What’s happening at xAI isn’t just a cost-cutting exercise, it’s a sign of a major shift in AI strategy. Reuters called it a shocking but decisive move, while Financial Express highlighted the Musk-style vetting and screening aspect. Controversial as it may be, there’s no denying that Elon Musk has once again put the industry on notice. The future of Grok, and the AI ​​race, will tell us whether this bet will pay off.
