Here are the key xAI figures who have departed in the recent exodus

  • Elon Musk’s AI startup is facing a flurry of top employee departures.
  • The departures included xAI cofounders Jimmy Ba and Tony Wu, who both thanked Musk for the opportunity.
  • More than half of xAI’s cofounders have left the startup since Musk founded it in 2023.

xAI is facing an exodus of top employees.

Two cofounders and at least eight other employees have announced their departures from Elon Musk’s AI startup in the past few days, with the billionaire telling xAI’s workforce in a Tuesday all-hands that the company was restructuring as it continues to grow.

In a post on X, Musk wrote that xAI had been reorganized “to improve speed of execution.”

“This unfortunately required parting ways with some people,” he wrote, adding that xAI was still “hiring aggressively.”

It comes after Musk announced that xAI would merge with his rocket company, SpaceX, in a deal the billionaire said would help the joint entity build a network of AI data centers in Earth’s orbit. I

In the Tuesday all-hands, which was posted on X, Musk said the combined company would aim to build a “self-sustaining” city and a catapult, or mass driver, on the moon to launch AI data center satellites into space.

SpaceX is reportedly gearing up for a massive public offering later this year that could value the company at as much as $1.5 trillion. That could be a major boost for xAI, which reportedly burned through billions of dollars last year.

The departures are the latest turmoil to hit the startup since Musk founded xAI in 2023 with the aim of taking on Google and OpenAI.

Since then, around half of the company’s cofounders have left, and xAI has faced global backlash over sexual images of real people generated on X by Grok, the startup’s AI chatbot.

Here’s everyone who has left xAI in the company’s most recent exodus. Business Insider has contacted each of the following employees for comment.

Tony Wu

xAI cofounder Tony Wu announced his resignation from the company on February 9. In a post on X, the former Google researcher said it was time for his “next chapter” and thanked Musk for “the ride of a lifetime.”

Business Insider’s Grace Kay previously reported that Wu began reporting directly to Musk last year and led xAI’s reasoning efforts.

Jimmy Ba

Jimmy Ba became the second xAI cofounder to announce his departure from the company in less than 48 hours.

The executive, who previously oversaw the startup’s AI tutoring efforts, also thanked Musk for the opportunity and said he was proud of what xAI had accomplished in a post on X.

Ba’s departure means that six out of the 11 cofounders who launched xAI with Musk in 2023 have now left the company.

Hang Gao

Hang Gao, a member of technical staff, also announced in an X post on February 10 that he had left xAI.

The Berkeley alumnus, who worked on xAI’s Grok Imagine AI video generator, described his time at the company as “unique and memorable.”

Vahid Kazemi

Vahid Kazemi, a member of xAI’s technical staff, said on X on February 11 that he had left the company a few weeks prior. “That was short! IMO, all AI labs are building the exact same thing, and it’s boring. I think there’s room for more creativity,” he wrote, adding that he was starting “something new.”

Kazemi joined xAI last year and, before that, worked at OpenAI. He also previously worked at Google and Apple.

Ayush Jaiswal

Ayush Jaiswal worked on Grok at xAI and announced on February 6 that it was his last week at the company. “Will be taking a few months to spend time with family & tinker with AI,” he wrote in a post on X. Jaiswal joined xAI in September 2025, according to his LinkedIn profile. Before that, he was head of growth at Scale AI.

Shayan Salehian

Shayan Salehian said on February 7 that he was leaving after a seven-year stint across Twitter and X to build something new.

He worked on the X timeline as well as various Grok models, he said in a post on X. He added that he is leaving to work on something “focused on accelerating science.”

“Working closely with Elon across X and xAI, I saw what happens when you refuse to accept impossible as an answer,” he wrote on X.

Simon Zhai

Simon Zhai, a member of the xAI technical staff, joined the company in October 2025 and announced his departure on February 9.

“Today is my last day at xAI, feeling very fortunate about the opportunity. It has been an amazing journey,” he wrote in a brief departure post on X. Before xAI, Zhai was a research scientist at Google DeepMind.

Andrew Ma

Member of technical staff Andrew Ma wrote in an X post on February 11 that he had left xAI this week.

Ma worked on X’s recommendation system and was “solely responsible” for writing a new version of the platform’s user search algorithm, according to his LinkedIn.

The former Twitter engineer praised xAI’s “wartime mentality” and thanked Musk for “creating this org that the world needs.”

Radhakrishnan Venkataramani

Radhakrishnan Venkataramani wrote in an X post on February 12 that he had left xAI this week.

The former Google and Facebook engineer joined xAI last July, per his LinkedIn, and worked on reasoning and reinforcement learning systems for Grok, as well as the company’s coding model.

In his farewell post, Venkataramani said he was “grateful” to have been part of xAI, calling the company “the most hardcore team ever.”

Rahul Ravishankar

Rahul Ravishankar, a member of technical staff at xAI, said February 13 was his last day at the company.

The Berkeley graduate, who joined Musk’s AI startup last year, wrote on X that leaving xAI was “one of the hardest decisions” he had ever made.

My rare plants sell for five figures. The business helps me support my extended family, but I work about 100 hours a week.

This as-told-to essay is based on a conversation with Harry Luu, owner of PlantZaddyTherapy. It has been edited for length and clarity.

I’ve always been a gardener and enjoyed being around plants. While I was in graduate school studying math, my collection of houseplants grew. There’s an attention to detail and a hyperfocus that I found in both mathematics and plants, so my hobby complemented my academic career.

During the pandemic, my interest in rare plants blew up. I started getting a bigger collection and trading up for more valuable plants.

Eventually, my hobby transformed into a business. I finished my graduate degree and started teaching math in California, but three years ago, I left academia to sell plants full-time.

My academic career was a safety net for my family of 8

I grew up in Vietnam, and I’m the embodiment of the American dream for my family. They put all their eggs in my basket, which allowed me to come to America and study. Now, I feel it’s fair to return their investment. I support not only myself and my husband, but also my parents, my brother, my sister-in-law, my niece, and my nephew.

Leaving my job while supporting a family of eight in California might seem risky, but it was calculated. I had reached the point where I saw the potential for financial freedom from investments I had made during grad school that had very good returns. I had years of data on plant sales, and also knew I could return to academia if needed, so I had a safety net.

I price based on rarity and desirability, without going too high

I was already connected to the rare plant community, so selling increasingly expensive plants felt like a natural progression. I grew my platform on Palmstreet, an online marketplace.

This year, I had two record-breaking sales in one day. I sold a $16,000 plant (an Anthurium Variegated Forgetii x Heinz, one of only two in the world), then a $26,000 plant (the only specimen of the True Variegated Lux Albo Mother Plant).

I’m a math person, so I use a formula to price. I calculate rarity and desirability and compare them with price data from the previous three years. These plants were both very rare and highly desirable, which drove prices up. However, I didn’t want to price them too high, because I’m thinking about the long-term viability for my brand: people have to be able to purchase what I’m selling. Given how rare the plants were, their five-figure prices weren’t too big a splash.

I want to be able to connect with the community more

Despite those big numbers, the business’s income fluctuates dramatically. My best single week was over $200,000 in sales, but other weeks I might have no sales. The market is seasonal, and winter is slow. I’ve had to adapt to not having a steady, reliable income.

The money comes and goes, but the work never stops. Right now, I spend about 100 hours a week on the business. We have plants in our home, and also a large greenhouse on our property. My brother does some of the maintenance care for the plants, but all the breeding decisions are made by me.

I’m on the cusp of the company being able to sustain itself without me working so much. I look forward to that — when I can step back from the business side and focus more on the joy of growing. I would like to share my knowledge about rare plants and take the plants on the road to connect with my community more, since that’s what got me hooked on growing in the first place.

Epstein files feature photos of some famous figures within the disgraced financier’s orbit

  • The Justice Department released a large trove of files related to the Jeffrey Epstein investigation.
  • Documents include photos of the disgraced financier with some high-profile figures.
  • The photos are not evidence of wrongdoing.

The Justice Department on Friday released thousands of documents related to its investigation of Jeffrey Epstein, the disgraced financier.

The trove of files, many of which were redacted, includes uncredited and undated photos that provide a snapshot into Epstein’s inner life and circle.

In 2008, Epstein pleaded guilty to solicitation of prostitution and solicitation of prostitution with a minor under the age of 18. Nine years later, the financier was charged with the sex trafficking of minors. He died by suicide in 2019 while in federal custody.

Some of the images are of his longtime associate Ghislaine Maxwell, who was convicted in 2021 on multiple felony counts, including the sex-trafficking of a minor. Other photos show the wide spectrum of high-profile figures Epstein came into contact with during his life.

The images include former President Bill Clinton, billionaire Richard Branson, actor Kevin Spacey, and The Rolling Stones lead vocalist Mick Jagger, among others.

The photos are not evidence of wrongdoing, nor do they detail what relationship the financier had with any of the figures. Some of the figures aren’t pictured with Epstein.

Here’s what the Friday document dump included. The following list is not exhaustive.

Clinton has shown up several times in investigations into Epstein, including in the flight logs of Epstein’s private jet. Clinton traveled internationally with Epstein on several occasions after his two terms as president ended in 2001.

There have been no public accusations of wrongdoing against Clinton related to his friendship with Epstein.

A spokesperson for Clinton did not respond to a request for comment from Business Insider.

In a statement posted on social media, Angel Ureña, a spokesperson to the former president, suggested that Clinton knew nothing about Epstein’s criminal activity.

“There are two types of people here. The first group knew nothing and cut Epstein off before his crimes came to light,” he wrote. “The second group continued relationships with him after. We’re in the first. No amount of stalling by people in the second group will change that.”
