But by the time I had a cup of coffee and began parsing all the cyber jargon, I was reassured that an apparent solution was on its way to plug a major new security hole that could make websites vulnerable to cyberintrusions. Since August, a coalition led by OpenAI has been working to address critical vulnerabilities in PHP, an open-source programming language that undergirds the web. But there was bad news, too: This type of long-simmering response to the latest AI-discovered vulnerabilities may not be viable for much longer. For months, OpenAI has been harping on what it calls the “defender’s window”—the critical period of time when cybersecurity experts, armed with advanced AI models, can identify and patch vulnerabilities before attackers exploit them first. The issue is that the gap is rapidly narrowing between cybercapable models from leading U.S. frontier labs and Chinese open-source models, which lack the restrictions U.S. labs impose on their models’ capabilities. Anthropic said as much in a blog post from late September warning that Chinese lab Z.ai’s GLM-5.3 model only lags the U.S. frontier models by about four months. The good news: The Trump administration has a shiny new organization created for moments just like these. It’s called the Super Intelligence Force, a name that may elicit eyerolls from some of our more jaded readers. Still, I have heard over and over that all the AI industry wants is coordination and clarity from the White House. That, presumably, is what the SI Force will offer, led by heavy hitters including National Intelligence Director Jay Clayton and senior Defense Department official Emil Michael. An OpenAI spokesperson told me today that they had briefed several agencies, including the Cybersecurity and Infrastructure Security Agency, about the PHP vulnerability, as well as briefing Clayton and Michael late last week, representing the first “major engagement” between OpenAI and the SI Force. The spokesperson added that the SI Force provided a central point to coordinate their communication across the broader government. According to a White House official, the SI Force’s work involved helping to put pressure on the “relevant parties” to deploy a vulnerability patch. While the SI Force’s coordination function may not seem terribly ambitious, at least it’s a start. It’s worth remembering that the White House essentially had to reorient its entire AI policy in April with the announcement of Mythos. The arrival of Chinese cybercapable open models could represent a Mythos 2.0 moment. I spoke with one former White House official who told me solutions from even a few months ago, like the July Gold Eagle clearinghouse that allows organizations and government agencies to share and fix software vulnerabilities, might already be outdated. It’s up to the SI Force to create a path forward. The next major internet bug likely won’t have the luxury of a two-month-long defender’s window. Meta’s Performance On Sunday, in a preview of this week’s Meta Platforms earnings report, your regular Briefing columnist, Martin Peers, declared: “If Meta can stay on investors’ good sides, an equity offering seems in the cards.” Martin nailed it on both accounts. On Wednesday afternoon, Meta CEO Mark Zuckerberg delivered a bunch of (mostly) good news that had investors in the company purring like kittens. Meta also announced the creation of a new category of common stock that will allow it to raise capital to fund its hefty AI inves
