Musk’s Grok 4 launches one day after chatbot generated Hitler praise on X

On Wednesday night, Elon Musk unveiled xAI's latest flagship models Grok 4 and Grok 4 Heavy via livestream, just one day after the company's Grok chatbot began generating outputs that featured blatantly antisemitic tropes in responses to users on X. Among the two models, xAI calls Grok 4 Heavy its "multi-agent version." According to Musk, Grok 4 Heavy "spawns multiple agents in parallel" that "compare notes and yield an answer," simulating a study group approach. The company describes this as t

How passkeys work: Your passwordless journey begins here

CollinsChin/Getty Images Over the last few decades, compromised usernames and passwords have typically been at the root of some of the most sensational, damaging, and costly data breaches. An incessant drumbeat of advice about how to choose and use strong passwords and how not to fall prey to social engineering attacks has done little to keep threat actors at bay. Additional factors of authentication, such as the transmission of one-time passwords or passcodes (OTPs) over SMS or email, are wid

Measuring the Impact of AI on Experienced Open-Source Developer Productivity

We conduct a randomized controlled trial (RCT) to understand how early-2025 AI tools affect the productivity of experienced open-source developers working on their own repositories. Surprisingly, we find that when developers use AI tools, they take 19% longer than without—AI makes them slower. We view this result as a snapshot of early-2025 AI capabilities in one relevant setting; as these systems continue to rapidly evolve, we plan on continuing to use this methodology to help estimate AI accel

Ars Live recap: Climate science in a rapidly changing world

The conversation then moved to the record we have of the Earth's surface temperatures and the role of Berkeley Earth in providing an alternate method of calculating those.

Lately, those temperatures have been unusually high, crossing 1.5° C above pre-industrial conditions for t

Could a Paper Plane Thrown from the ISS Survive the Flight?

Sometimes there are profound questions in life that must be answered, like "What is the meaning of existence?", "Are we alone in the universe?" or "What happens if you throw a paper airplane from the International Space Station?" Luckily, that third one has finally been answered, because of course someone would eventually. A new paper from Maximilien Berthet and Kojiro Suzuki from the University of Tokyo looks at "the dynamics of an origami space plane during Earth atmospheric reentry" – in ot

US appeals court blocks FTC’s ‘click-to-cancel’ rule for subscriptions

In Brief A U.S. appeals court has blocked the Federal Trade Commission’s “click-to-cancel” rule that would have required companies to make it as easy to cancel a subscription as it was to sign up. The rule was set to take effect on July 14. Reuters reports that the 8th U.S. Circuit Court of Appeals in St. Louis said on Wednesday that the FTC, which passed the rule under former Democratic Chair Lina Khan, had failed to conduct a preliminary analysis of the costs and benefits of the rule.
