Elon Musk is reportedly planning an xAI supercomputer to power a better version of Grok


Elon Musk told investors this month that his startup xAI is planning to build a supercomputer by the fall of 2025 that would power a future, smarter iteration of its Grok chatbot, The Information reports. This supercomputer, which Musk reportedly referred to as a “gigafactory of compute,” would rely on tens of thousands of NVIDIA H100 GPUs and cost billions of dollars to build. Musk has previously said the third version of Grok will require at least 100,000 of the chips — a fivefold increase over the 20,000 GPUs said to be in use for training Grok 2.0.

According to The Information, Musk also told investors in the presentation that the planned GPU cluster would be at least four times the size of anything used today by xAI competitors. Grok is currently in version 1.5, which was released in April, and is now touted to process visual information like photographs and diagrams as well as text. X earlier this month started rolling out AI-generated news summaries powered by Grok for premium users.

X is using Grok to publish AI-generated news summaries


X is using Grok to publish AI-generated summaries of news and other topics that trend on the platform. The feature, which is currently only available to premium subscribers, is called “Stories on X,” according to from the company’s engineering account.

According to X, Grok relies on users’ posts to generate the text snippets. Some seem to be more news-focused, while others are summaries of conversations happening on the platform itself. One user a screenshot that showed stories about Apple’s earnings report and aid to Ukraine, as well as one for “Musk, Experts Debate National Debt,” which was a summary of a “candid online discussion” between Musk and other “prominent figures” on X.

If any of this sounds familiar, it’s also remarkably similar to Moments, the longtime Twitter feature that curated authoritative tweets about important news and cultural moments on the platform. The feature, which was overseen by a team of human staffers, was killed

Like other generative AI tools, Grok’s summaries come with a disclaimer. “This story is a summary of posts on X and may evolve over time,” it says. “Grok can make mistakes, verify its outputs.” Grok, of course, doesn’t exactly have the best track record when it comes to accurately interpreting current events. It previously generated a suggesting that NBA player Klay Thompson went on a “vandalism spree” because it couldn’t understand what “throwing bricks” meant in the context of a basketball game.



Tesla layoffs hit high performers, some departments slashed, sources say


Tesla management told employees Monday that the recent layoffs — which gutted some departments by 20% and even hit high performers — were largely due to poor financial performance, a source familiar with the matter told TechCrunch.

The layoffs were announced to staff just a week before Tesla is scheduled to report its first-quarter earnings. The move comes as Tesla has seen its profit margin narrow over the past several quarters, the result of an EV price war that has persisted for at least a year. The company delivered a record 1.81 million vehicles in 2023. Its margins, however, took a hit after Tesla repeatedly slashed prices in a bid to drum up sales and undercut the competition.

Tesla informed employees that more than 10%, or about 14,000 workers, will be laid off across the global organization that has operations in the United States, Europe and China. In a regulatory filing, Tesla referred to the l layoffs as a “company-wide restructuring.” The layoffs, which affected employees across all departments and seniority levels, were made to reduce costs and increase productivity to prepare for its “next phase of growth,” according to an internal email from CEO Elon Musk that TechCrunch has viewed.

High performers also cut

Many of the laid-off employees were high performers, according to two sources who spoke to TechCrunch on condition of anonymity. One source expressed shock at the number of talented employees cut and noted that many of those affected were working on projects that have fallen lower on Tesla’s priority list. The source declined to specify which projects.

Some departments saw layoffs beyond the 10% outlined in the companywide email, according to sources. One manager told TechCrunch that 20% of their employees were cut.

“I lost 20% of my team, some really good players too,” they said.

The shakeup also comes as Musk continues to bend the company’s trajectory toward building fully self-driving cars. Tesla recently dropped plans to build a lower-cost EV that would retail starting at around $25,000, opting instead to use the underlying platform being developed to power an alleged robotaxi that Musk said will debut August 8.

Musk previously tried to prioritize the dedicated robotaxi vehicle project, according to his biographer, Walter Isaacson. In 2022, he told employees that he wanted a “clean robotaxi” with no steering wheel or pedals. Tesla lead designer Franz von Holzhausen and engineering VP Lars Moravy kept running the low-cost EV project in secret and eventually convinced him to make both — that is, until last week when it was reported that Musk changed his mind.

Top execs leave

Two high-profile executives — Drew Baglino, Tesla’s SVP of Powertrain and Energy, and Rohan Patel, VP of Public Policy and Business Development — also left the company.

Patel told TechCrunch he decided Sunday evening to leave Tesla because of “[b]ig overall changes” at the company. Patel, who had been engaging regularly with Tesla customers and fans on X in recent months, declined to be specific. He noted in a message that it would be “Better for me not to speculate.” “Tesla is going to be stronger than ever, and change is good,” he added.

Baglino told TechCrunch that after 18 years it was time to leave Tesla. “I feel good about the impact I’ve been able to achieve, my leadership team is strong, the energy businesses I’m responsible for are doing well, etc.,” he wrote in a message to TechCrunch.

“Baglino was in charge of powerdrives and new battery projects, and there’s a sense that there isn’t a whole lot of innovation that’s sustainable at this point, which is probably why Baglino is leaving,” Sandeep Rao, head of research at London-based financial services company Leverage Shares, theorized in an interview with TechCrunch.

Baglino’s departure comes just a few months after Tesla’s previous CFO, Zachary Kirkhorn, stepped down. In January, Musk posted on X, formerly Twitter, that he would want to have around 25% voting control of Tesla in order to focus more fully on the company, rather than on his other companies, and help the EV-maker become a leader in AI and robotics.

This article was updated to include information from a regulatory filing that refers to the layoffs as a “restructuring.”



X names its third head of safety in less than two years


X has named a new head of safety nearly a year after the last executive in the position resigned. The company said Tuesday that it had Kylie McRoberts to Head of Safety and hired Yale Cohen as Head of Brand Safety and Advertiser Solutions.

The two will have the unenviable task of leading X’s safety efforts, including its attempts to reassure advertisers that the platform doesn’t monetize or . The company said earlier this year it planned 100 new safety employees after much of its safety staff.

Head of safety has been a particularly fraught position since Elon Musk took over the company previously known as Twitter. Musk has previously clashed with his safety leads and McRoberts is the third person to hold the title in less than two years. Previously, Yoel Roth shortly after the disastrous rollout of Twitter Blue in 2022. Roth was replaced by Ella Irwin, who last year after Musk publicly criticized employees for enforcing policies around misgendering.

Not much is known about McRoberts, but she is apparently an existing member of X’s safety team (her X account is currently private and a appears to have been recently deleted). “During her time at X, she has led initiatives to increase transparency in our moderation practices through labels, improve security with passkeys, as well as building out our new Safety Center of Excellence in Austin,” X said in a statement.
