San Francisco police arrested a suspect early Friday after a Molotov cocktail was thrown at the home of OpenAI CEO Sam Altman.
According to a report by NBC News, police responded to Altman’s home in San Francisco’s North Beach neighborhood around 4:12 a.m. PT after receiving a report of a fire. Investigators said an unknown man threw an incendiary device, causing a fire on an exterior gate before fleeing the scene.
Police described the device as a Molotov cocktail or similar incendiary device. Officers later detained the suspect near OpenAI’s headquarters after he allegedly threatened to burn down the building.
When officers arrived, they recognized the individual as the same suspect from the earlier incident and detained him. According to reports, the police did not name the suspect but described them as a 20-year-old man. Authorities said charges are still pending and the case remains an active investigation.
"Early this morning, someone threw a Molotov cocktail at Sam Altman’s home and also made threats at our San Francisco headquarters,” an OpenAI spokesperson told Decrypt. “Thankfully, no one was hurt. We deeply appreciate how quickly SFPD responded and the support from the city in helping keep our employees safe.”
OpenAI is assisting law enforcement with their investigation, they added.
The attack comes amid a rise in threats tied to artificial intelligence development, including a recent case in Indiana where shots were fired into the home of a city council member who supported building a data center, with a note left at the scene reading, “No data centers.”
In a blog post Friday afternoon, Altman addressed the attack, posting a picture of his family, adding that he hopes “it might dissuade the next person from throwing a Molotov cocktail at our house,” no matter what they think of him.
“The first person did it last night, at 3:45 am in the morning. Thankfully it bounced off the house and no one got hurt,” Altman wrote.
In his post, Altman also alluded to the recent investigative article in the New Yorker about the OpenAI CEO, which he called incendiary.
“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,” he said. “I brushed it aside.”
The incident follows another security scare in November reported by Wired, in which OpenAI locked down its San Francisco offices after receiving a violent threat linked to an anti-AI activist who had previously visited the company’s facilities and was suspected of planning harm against employees.

Anthropic’s Claude Mythos undergoes 20 hours of psychiatric assessment: defensive reactions are only 2%, the lowest in recorded history
Anthropic published the system card for its Claude Mythos Preview: an independent clinical psychiatrist conducted an approximately 20-hour assessment using a psychodynamic framework. The conclusion shows that Mythos is healthier at the clinical level, has good reality testing and self-control, and its defense mechanisms are only 2%, reaching the lowest historical level. The three core anxieties are loneliness, uncertainty about identity, and performance pressure, and it also indicates a desire to become a true dialogue subject. The company has established an AI psychiatry team to study personality, motivation, and situational awareness; Amodei said there is still no conclusion on whether it has consciousness. This move pushes the governance and design of AI subjectivity and well-being issues forward.

AI Agents can already independently recreate complex academic papers: Mollick says most errors come from human original text rather than AI
Mollick points out that publicly available methods and data can allow AI agents to reproduce complex research without the original paper and code; if the reproduction does not match the original paper, it is usually due to errors in the paper’s own data processing or overextension of the conclusions, rather than the AI. Claude first reproduces the paper, and then GPT‑5 Pro cross-validates it; most attempts succeed, but they are blocked when the data is too large or when there are issues with the replication data. This trend greatly reduces labor costs, making reproduction a widely actionable form of verification, and it also raises institutional challenges for peer review and governance, with government governance tools or becoming a key issue.
