The technology is far from the only existential risk our species faces. But weighing such cosmic fears can become a mind-bending exercise.

A controversy around OpenAI’s latest math proof raises a fear that might become increasingly common: that A.I. tools could take valuable insights from one user and hand them to another.

OpenAI announced today that it had solved the problem, one of seven “Millennium Problems” seen as among the most important in higher mathematics.

A OpenAI afirmou na terça-feira (8) que sua mais nova tecnologia de inteligência artificial havia solucionado um dos chamados Problemas do Milênio, um conjunto de importantes questões matemáticas ainda sem resposta, criado para levar os principais matemáticos do mundo a novos patamares.

A co-founder of xAI is going all in on building open-source artificial intelligence so that “anyone can control and shape A.I. for their own needs.”

Minutes after four top researchers said they were leaving, Google said that Demis Hassabis, the Nobel-winning scientist who led the company’s A.I. lab, was stepping into a new job.

Jeff Dean, who for years was one of Google’s most important executives, is leading the new artificial intelligence company with the backing of Google.

The two companies struck a deal in 2024 to offer A.I. services on Apple devices, but their partnership has soured.

The company said on Friday night that the federal government had ordered limits on its Mythos and Fable 5 A.I. systems, citing national security concerns.

As co-chief executive of the start-up Prometheus, the Amazon founder is using A.I. to improve how devices ranging from computers to jet engines are made.

Called Claude Fable 5, it is twice as expensive as the company’s previous flagship system.

The company hopes to raise billions in a highly anticipated public offering that could unlock a new generation of tech industry wealth.

The LinkedIn co-founder was a key bridge to Microsoft’s relationship with OpenAI, but he also came with some baggage.

A San Francisco start-up called Arena found that people are most likely to use A.I. agents on the job, particularly if they are in the tech industry.

Researchers at the University of Toronto showed how hackers could use artificial intelligence to create a program that could target any known flaw in the world’s computers.

Anthropic raised $65 billion in new fund-raising that put its value at $900 billion, ahead of OpenAI’s last valuation of $730 billion, as the companies duel for A.I. dominance.
