Elon Musk surprisingly dropped the complaint against OpenAI.

Elon Musk has suddenly requested that a California court discontinue a legal case against OpenAI and its CEO Sam Altman, accusing them of forsaking the company's basic objective of developing artificial intelligence (AI) for humanity's benefit.

The multibillionaire's lawyers filed a motion to dismiss the months-old case, but provided no explanation for the decision. 

It came only a day before the court was scheduled to hear the ChatGPT developer's request to have the case dismissed. 

BBC News has contacted Mr Musk's lawyer and OpenAI for a comment.

 The most recent motion requested that the case be dismissed "without prejudice," which means that Mr Musk might restart it later.

 The Tesla CEO launched the complaint against OpenAI at the end of February this year, claiming that the business he helped start in 2015 had strayed from its philanthropic intentions in favor of making money.

OpenAI argued that Mr Musk had previously supported the notion of a for-profit structure, even proposing a combination with his electric vehicle company Tesla.

 The feud heated up earlier this week when Apple announced a partnership with OpenAI to improve its Siri voice assistant and operating systems using OpenAI's ChatGPT chatbot. 

Following the news, Mr Musk took to his social media network X, formerly known as Twitter, to criticize the partnership.

One of the posts concluded with the phrase "Apple has no idea what's going on once they hand over your data to OpenAI." "They are selling you down the river.

However, investors appeared to be pleased with the news, as Apple's stock market value soared to a record high of more than $3 trillion.

 In July 2023, Mr Musk founded his own AI company, xAI, with the goal of "understanding reality". 

In November of same year, xAI developed Grok, a chatbot with "a little humour" to compete with ChatGPT.
