OpenAI is suing Elon Musk for unfair competition and interfering with its business relationships with investors and customers, escalating a legal battle between the ChatGPT maker and the billionaire who helped bankroll the artificial intelligence startup a decade ago.

The allegations against Musk were filed  in a federal court in California as a counterclaim to the Tesla CEO’s lawsuit against OpenAI, which is heading to a jury trial next year.

Musk, an early OpenAI investor who now runs his own AI firm, xAI, along with Tesla, SpaceX, social media platform X and President Donald Trump’s Department of Government Efficiency, began a legal offensive against OpenAI and its CEO Sam Altman more than a year ago.

He first sued for breach of contract over what he said was the betrayal of its founding aims as a nonprofit research laboratory, and later expanded his claims.

Cabot Creamery butter recalled

A Vermont firm has recalled more than 1,700 pounds of butter because it may be contaminated with coliform, a type of bacteria found in fecal matter.

Agri-Mark Inc., of Waitsfield, Vermont, recalled 189 cases of Cabot Creamery 8-ounce premium butter made with sea salt, according to a notice from the U.S. Food and Drug Administration.

The butter was distributed in Arkansas, Connecticut, Maine, New Hampshire, New York, Pennsylvania and Vermont.

The recall was issued on March 26 and is ongoing, according to the FDA. It is classified as the lowest level of recall, Class III, which means it’s not likely to cause health problems in people.

Consumers should not eat or use the recalled butter, which has a best-by date of Sept. 9. It is identified as lot 090925-055, item 2038.
