Elon Musk’s rocket company said its artificial intelligence spending had soared, but revenue more than doubled from its Starlink internet satellite service and A.I. products.

The Philadelphia Police Department said the agents had also sent in a false homicide tip. The incidents led the White House to call for better disclosure of rogue A.I. behavior.

Reviews by the Canadian Center for Child Protection and The New York Times found that explicit images of children remain on the social media site owned by Elon Musk.

Their warnings echo concerns that other artificial intelligence experts have voiced in recent months, as calls increase for a slowdown in the pace of development.

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.

The voluntary review process will cover closed-source artificial intelligence models, but exclude those that publish the underlying code.

The disclosure followed OpenAI’s report last week that its own artificial intelligence had hacked into the network of an online library.

Anthropic and OpenAI are clashing with the rest of the tech industry over whether “open-source” models from China should be freely available or restricted.

Google’s parent company, which has spent heavily on artificial intelligence, also showed growth across its businesses, particularly in cloud computing.

Elon Musk’s rocket company said Google would pay it $920 million a month, as it prepared for its initial public offering.
