In the trial’s first day of testimony, Elon Musk said greed led co-founder Sam Altman to pull the A。 lab away from its nonprofit roots。 OpenAI says that’s nonsense
Elon Musk was cross-examined on the third day of the trial over his lawsuit against Sam Altman and OpenAI
One of Elon Musk’s abiding fears is that A。 could one day threaten humans。 But the jurors deciding his suit against OpenAI probably won’t hear about it
编辑：桃子 【新智元导读】大型翻车现场。起诉OpenAI「背叛使命」的马斯克，竟亲口承认自家Grok模型蒸馏了ChatGPT。 对薄公堂第四天，马斯克爆出了大瓜
ChatGPT’s new privacy policy states how the company uses cookies for tracking, to turn free users into paying subscribers
Will the rising tide of A。 adoption lift all boats
For the first time, scientists have watched a subduction zone literally fall apart beneath the ocean floor。 Using advanced seismic imaging, they found the Juan de Fuca plate splitting into fragments as it sinks beneath North America。 Rather than collapsing all at once, the plate is tearing piece by piece, like a train slowly derailing

The AI firm said that unlike previous model bugs, the issue "crept in subtly"
Scientists have created a powerful new way to control quantum systems, achieving the first-ever demonstration of quadsqueezing—an elusive fourth-order quantum effect。 By combining simple forces in a clever way, they made previously hidden quantum behaviors visible and usable, opening new frontiers for quantum technology
A light-sensitive crystal is opening the door to a new era of “light-written” technology。 Arsenic trisulfide can be reshaped and permanently altered using simple light, creating ultra-fine optical patterns without expensive manufacturing tools。 Scientists even etched a nanoscale portrait of Einstein and high-density patterns that could act as secur
Scientists have pulled off a first: teleporting a photon’s state between two separate quantum dots。 This was done over a 270-meter open-air link, proving quantum information can travel between independent devices。 The achievement marks a key step toward building quantum networks for ultra-secure communication
A major discovery is reshaping how scientists think about catalysts。 Researchers have, for the first time, captured oxygen atoms moving through the interior of a catalyst—not just along its surface。 This reveals that the bulk material can actively participate in reactions, opening a new frontier in catalyst design
The case over OpenAI's history and public commitments could have major implications for the future of AI
Build American AI, a nonprofit linked to a super PAC bankrolled by executives at OpenAI and Andreessen Horowitz, is funding a campaign to spread pro-AI messaging and stoke fears about China
Physicists are rethinking one of quantum mechanics’ biggest puzzles: how fuzzy possibilities become definite reality。 New research suggests that spontaneous “collapse” processes—possibly linked to gravity—could subtly blur time itself。 This wouldn’t affect clocks we use today, but it reveals a hidden limit to how precise time can ever be
