I feel someone just gave them a huge $$$ offer that they couldn't say no too. Given Elon Musk is praising their efforts, and he lost a lot of his original XAI team recently, my money is on Elon.

FWIW, the article quotes people close to the researchers saying that the departure wasn't their choice.

A bit hard for him to swing if he wants to position xAI as a key Defense contractor for AI and his company is full of Chinese Nationals...

Is there a leading American AI research organization - big tech or academia - that isn't "full of Chinese Nationals"? If the DoD want an all-American SoTA model, they may have to wait for a while.

Maybe true but you probably expect a minimum of leaked information directly to the CCP if you accept that.

AI Research orgs voluntarily do their own "leaking" via the publication of research papers, and involuntarily via employee/post-doc churn.

The guilty-until-proven innocent mindset is what kickstarted China's nuclear program - and led to the internment of people with Japanese heritage.

Nobody with talent wants to work with Elon or xAI

The only people he attracts are h1b candidates who have limited choices

You can broaden that. A lot of talent doesn't want anything to do with the USA.

The US is the number one destination for skilled immigrants on the planet. Nobody else pays as well.

That trend is reversing, because of course it is.
