The Future of Life Institute published an open letter titled “Pause Giant AI Experiments,” which calls on all organizations training AI more powerful than GPT-4 to pause for the next six months.

Signed by over 1,100 people, the letter has the support of notable figures such as Elon Musk, Steve Wozniak, and Yuval Noah Harari.

Musk has been outspokenly critical of OpenAI, and tweeted in February that “OpenAI was created as an open source (which is why I named it “Open” AI), non-profit company to serve as a counterweight to Google, but now it has become a closed source, maximum-profit company effectively controlled by Microsoft. Not what I intended at all.”
