Silicon Valley and corporate America are increasingly turning to cheaper, open-source artificial intelligence models built in China.

President Trump touched on what is an increasingly hot topic in Washington: how average Americans can get a piece of the tech industry’s A.I. windfall.

One is allied with Anthropic. The other is tied to OpenAI. They’re both spending millions to influence the midterms, and they’re leaving a trail of fearful candidates and canceled ads in their wake.

Ishmael Reed, provocateur and playwright, has a few words for the billionaires of Silicon Valley.

Greg Brockman, OpenAI’s president, testified in a trial pitting Mr. Musk against his company that the world’s richest man was eager to change how it operated as a nonprofit.

Plus, why nursing homes are hiring M.M.A. fighters.

In the trial’s first day of testimony, Elon Musk said greed led co-founder Sam Altman to pull the A.I. lab away from its nonprofit roots. OpenAI says that’s nonsense.

Mr. Musk’s posts on X have pushed his narrative that OpenAI has lost its way.

Elon Musk, Sam Altman and several other key artificial intelligence industry figures are slated to testify in the trial, which is expected to last several weeks.

Mr. Musk’s lawsuit against Mr. Altman and OpenAI makes the case that all-encompassing greed is Silicon Valley’s defining feature.

Mr. Altman, who has faced criticism over OpenAI’s direction, has culled company projects and is trying to be more disciplined with strategy.

A jury trial that is set to start on Monday could shift the course of the A.I. race, with Mr. Musk seeking billions of dollars in damages from Mr. Altman’s OpenAI.

Nothing artificial about this Hollywood A.I. smackdown.

Negotiations, threats and amended contracts have left plenty of questions. Here are some answers.

A fight over Pentagon contracts shows how the leaders of Silicon Valley’s two most important A.I. start-ups are feuding over the future of the tech industry.

The artificial intelligence start-up has reportedly resumed talks with the Defense Department over use of its tools, with high stakes for both.

The new pact includes additional protections to prevent the use of the company’s technology for mass surveillance of Americans.

The Pentagon and Anthropic were close to agreeing on the use of artificial intelligence. But strong personalities, mutual dislike and a rival company unraveled a deal.

The deal came hours after President Trump had ordered federal agencies to stop using artificial intelligence technology made by Anthropic, an OpenAI rival.

Actions by the president and the Pentagon appeared to drive a wedge between Washington and the tech industry, whose leaders and workers spoke out for the start-up.

The tech heroes turned zeros are leading us to our doom.
