San Francisco police arrested a suspect for allegedly throwing a Molotov cocktail at the home of OpenAI CEO Sam Altman.

“Officers made an arrest, and no injuries were reported as a result of this incident,” San Francisco police stated.

In a blog post on his website, Altman shared a photograph of his family: “Here is a photo of my family. I love them more than anything,” he wrote above an image of his husband and son.

“Normally we try to be pretty private, but in this case I am sharing a photo in the hopes that it might dissuade the next person from throwing a Molotov cocktail at our house, no matter what they think about me,” he added.

The San Francisco Police Department reported officers responded to a home in the North Beach neighborhood at 4:12 a.m. Friday “regarding a fire investigation.”

“Thankfully, no one was hurt,” OpenAI stated.

“We deeply appreciate how quickly SFPD responded and the support from the city in helping keep our employees safe. The individual is in custody, and we’re assisting law enforcement with their investigation,” OpenAI added.

Altman also noted that words hold significant power: “There was an incendiary article about me a few days ago. Someone said to me yesterday they thought it was coming at a time of great anxiety about AI and that it made things more dangerous for me. I brushed it aside. Now I am awake in the middle of the night and pissed, and thinking that I have underestimated the power of words and narratives. This seems like as good of a time as any to address a few things,” he wrote.

He elaborated: “Not all will go well” as the AI industry continues to roll out world-shifting tools. “The fear and anxiety about AI is justified; we are in the process of witnessing the largest change to society in a long time, and perhaps ever. We have to get safety right, which is not just about aligning a model — we urgently need a society-wide response to be resilient to new threats.”

Altman stressed that “AI has to be democratized; power cannot be concentrated,” and it is not right for only a few AI labs to make “the most consequential decisions about the shape of our future.” He acknowledged conflicts with OpenAI’s board, noting the founder was fired only to be re-hired following an investigation: “I am not proud of handling myself badly in a conflict with our previous board that led to a huge mess for the company.”

“We have made many mistakes throughout the insane trajectory of OpenAI; I am a flawed person in the center of an exceptionally complex situation, trying to get a little better each year,” he wrote. “We knew going into this how huge the stakes of AI were, and that personal disagreements between well-meaning people would be amplified.”

Altman concluded with pride in OpenAI’s achievements: “Against all odds, we figured out how to build very powerful AI, amass enough capital to build infrastructure, create a product company and business, and deliver reasonably safe and robust services at a massive scale.”
