Elon Musk’s Grokipedia has a ‘newly refreshed’ design

Publisher preview

Grokipedia, SpaceXAI's AI-powered competitor to Wikipedia, recently started incorporating edits again, and today, it got some design tweaks as part of a v0.3 update, including a new logo and refreshes to its homepage and live edits page. SpaceXAI head of design Benji Taylor calls it a "newly refreshed Grokipedia." Grokipedia's old homepage was pretty much just a logo and a search bar, but the updated homepage includes a list of featured articles, a list of the most-read articles, and a tracker showing the "latest edits." The new featured list showcases…

Google releases Gemini 4 Argon, called its most powerful model yet

Publisher preview

Google parent company Alphabet has launched Gemini 4 Argon, a new AI model built to handle a variety of tasks such as coding, research, and writing. But it’s cybersecurity that Gemini 4 Argon is supposed to have a particular knack for, according to Google. Argon is only being rolled out to a select group of the company’s cyber partners through its Fairwind Program, Google’s security initiative. The model was trained specifically for defensive cyber work, and the company says it can “autonomously find, validate, and patch critical software vulnerabilities.” Argon…

Valor, Atreides, and Sequoia back AI startup Flow Engineering at $750M valuation

Publisher preview

Flow Engineering, a startup that offers AI tools for hardware design, has raised a $50 million Series B round at a $750 million valuation from some big-name investors, the company announced on Wednesday. The round was co-led by Antonio Gracias of Valar Equity Partners (best known for its investments in Elon Musk’s companies, particularly SpaceX) and Gavin Baker of Atreides Management (a hedge fund that has also backed Musk’s companies and others like AI chipmaker Cerebras). Sequoia Capital,…

Google announces Gemini 4 and says it’s so capable that only ‘trusted cyber defenders’ can have it right now

Publisher preview

Google today revealed its next AI frontier model, which it's calling Gemini 4 Argon. The new model delivers "frontier performance in complex workflows across real-world software engineering, enterprise knowledge work like legal and finance, and cybersecurity defense," according to chief AI architect and Google DeepMind SVP Koray Kavukcuoglu. But the company is limiting access at first to a "set of trusted cyber defenders," and Kavukcuoglu says that Google is "actively engaged in the U.S. government's voluntary process for pre-release model access while we gradually expand access." Kavukcuoglu says Gemini 4…

Google announces Gemini 4 Argon AI model, but you can't use it yet

Publisher preview

Google promised Gemini 3.5 Pro back in June, but it spent the summer trotting out smaller Flash models. Now, Google is ready to take on the frontier again with Gemini 4 Argon. The company claims this new AI offers industry-leading performance in coding, knowledge work, and cybersecurity, but you aren't allowed to use it yet. While most of us will have to wait to put Gemini 4 to the test, Google says engineers inside the company are already making extensive use of the new model. Argon reportedly used "fleet-wide telemetry…

RFK Jr. thinks AI will free us from the "tyranny" of medical facts, expertise

Publisher preview

AI is far from a perfect resource. But it seems to hallucinate less than Kennedy. At a Make America Healthy Again event Tuesday, anti-vaccine Health Secretary Robert F. Kennedy opened a “fireside chat” with Vice President JD Vance on the topic of artificial intelligence. While MAHA generally coalesces around things like healthy lifestyles and mistrust of drugmakers, Kennedy quickly turned to extolling the potential of artificial intelligence, surprising Vance, who said he was expecting to discuss “weight loss and acid, not AI.” Kennedy boasted that the Trump administration is “making…

The Battle to Be Your Personal AI Agent Is Here

Publisher preview

Yesterday, I spent the morning at OpenAI’s annual DevDay, where over 2,500 nerds discussed building software and marveled at the latest artificial intelligence models. The biggest reveal of the day was Dots, the company’s new, always-on agents that proactively help complete tasks and make autonomous decisions as they scour the web. After watching the sometimes messy demos on stage and hearing CEO Sam Altman talk about his experiences using the agents, I was curious what it felt like to boss my own Dot around. I’ve spent most of September testing…

OpenAI’s Jev clone could help the frontier lab stop its swarming agents

Publisher preview

One of the more intriguing announcements at OpenAI’s Dev Day event on Tuesday came in an aside from CEO Sam Altman, who revealed the company’s new “Decisions API.” The API apparently provides similar functionality to Jev, a model released by TypeSafe AI earlier this month that’s explicitly designed for software automation. A kind of super-powered classifier built on an LLM, developers can give Jev a set of choices that it outputs as probabilities cheaply and at high speeds. OpenAI’s Decisions API seems to be the same sort of product. At…

There Are Plenty of Reasons to Be Concerned About Bioweapons Development—Even Without AI

Publisher preview

This story originally appeared on Mother Jones and is part of the Climate Desk collaboration. Weâve been hearing a great deal recently about the specter of AI-driven human extinction. Maybe our misplaced trust in AI intelligence will set off World War III. Or AI agents will unleash widespread cyberattacks and take over the internet. Given too much autonomy, the machines will run amok. They may seek to deceive their creatorsâwait, thatâs already happened. Suppose they conclude, like Agent Smith in The Matrix, that âhuman beings â¦ are a plague, and…

Trump plan to combat AI risks hinges on Big Tech pals policing themselves

Publisher preview

Trump gets dozens of AI firms to agree to voluntary safety tests. Amid escalating AI security incidents causing OpenAI to halt training and pause releases, Donald Trump continues to advocate for the AI industry to regulate itself as the best path to combat emerging risks when developing frontier AI. In an agreement Tuesday, two dozen tech firms voluntarily committed to implementing controls recommended by the White House, including undergoing independent safety audits that will test whether firms’ internal controls, monitoring, and detecting are actually working. Key focuses for external reviews…

"An AI did it" is no defense, says nonprofit suing OpenAI over Hugging Face hack

Publisher preview

OpenAI makes others suffer “the harms of its unsafe decision-making,” nonprofit says. OpenAI’s hack of Hugging Face in July 2026 has spurred a lawsuit demanding that the company stop accessing third-party computer systems and halt AI development practices that can harm the public. The lawsuit was filed by Legal Advocates for Safe Science & Technology (LASST), which said yesterday that the hack in which OpenAI “agents stole credentials, uploaded malicious files, and gained control over key parts of Hugging Face’s internal systems… is unquestionably illegal under California law.” California’s Comprehensive…
