Investing.com -- A U.S. jury on Monday found OpenAI not liable in a lawsuit filed by Elon Musk, who claimed the artificial intelligence company had abandoned its original mission to benefit humanity.

The highly publicized trial started on April 28 and lasted 11 days. Musk alleged that OpenAI wrongfully sought to enrich investors and insiders at the expense of its nonprofit structure and failed to prioritize AI safety. He also claimed that Microsoft was aware OpenAI prioritized financial gain over altruistic goals.

OpenAI argued that Musk pursued the lawsuit for financial reasons and waited too long to claim the company breached its founding agreement to develop safe artificial intelligence for humanity's benefit.

During closing arguments, Musk's lawyer Steven Molo told jurors that multiple witnesses questioned the credibility of OpenAI CEO Sam Altman or called him a liar. Molo noted that Musk himself did not give an unqualified yes when asked during the trial if he was completely trustworthy.

The trial centered on questions about how artificial intelligence should be used and who should benefit from it financially. The technology is currently used for education, facial recognition, financial advice, journalism, legal research, and medical diagnoses.
