OpenAI gates GPT‑5.4‑Cyber amid executive attack
OpenAI restricted access to GPT‑5.4‑Cyber to vetted U.S. and U.K. institutes and selected partners while describing the model’s capabilities for reverse engineering and vulnerability analysis. At the same time, a man is accused of attacking Sam Altman’s home with a Molotov cocktail; his attorney says the suspect was in a mental‑health crisis, a development covered alongside the model’s limited release.

OpenAI is limiting its new GPT‑5.4‑Cyber model to vetted defenders as prosecutors pursue attempted murder and arson charges in the attack on Sam Altman’s home. (openai.com) (pbs.org) OpenAI said on April 14 that it is scaling its Trusted Access for Cyber program to “thousands” of verified individual defenders and “hundreds” of teams, starting with a GPT‑5.4 variant tuned to be more permissive for defensive security work. (openai.com) The company said GPT‑5.4‑Cyber is meant to help with binary reverse engineering, malware analysis, and vulnerability review of compiled software, while access is being routed through identity checks and other trust controls. (openai.com 1) (openai.com 2) That release lands a month after OpenAI introduced GPT‑5.4 as its flagship professional model with up to 1 million tokens of context and native computer-use features in the application programming interface and Codex. (openai.com) OpenAI has been tightening cyber policy for months. In February, it launched Trusted Access for Cyber with $10 million in application programming interface credits and said its frontier models could now work autonomously for hours or days on complex tasks, creating both defensive value and misuse risk. (openai.com) The parallel legal story is moving through San Francisco courts. PBS, citing the Associated Press, reported that Daniel Moreno-Gama, 20, is accused of throwing a Molotov cocktail at Altman’s home on April 10, setting an exterior gate on fire before later going to OpenAI’s headquarters and threatening to burn it down. (pbs.org) Judge Kenneth Wine ordered Moreno-Gama held without bail and set arraignment for May 5, according to the April 14 court report. Prosecutors say no one was injured, and San Francisco District Attorney Brooke Jenkins said the state case includes two attempted murder counts and attempted arson. (pbs.org) (apnews.com) Moreno-Gama’s public defender, Diamond Ward, said he was in an “acute mental health crisis,” is autistic, and was overcharged; Jenkins disputed that account and called it a targeted attack that would be prosecuted the same way regardless of the victim’s status. (pbs.org) (nbcbayarea.com) Federal authorities have also filed charges. The United States Attorney’s Office case, as summarized by regional reporting, alleges attempted damage or destruction of property by means of explosives and possession of an unregistered firearm tied to the April 10 attacks. (sfgate.com) OpenAI’s message is that more capable cyber tools will be released in stages, with broader access tied to stronger screening and monitoring. The court case now turns to the May 5 arraignment, while the company keeps GPT‑5.4‑Cyber behind a gate. (openai.com) (pbs.org)
