Elon Musk sues OpenAI and Sam Altman for "betraying" an initial agreement. "They abandoned the original mission of the society," he said.

Musk left OpenAI in 2018 and is now one of the company's most critical, and also founded his own artificial intelligence company, Xai, in 2023. OpenAI did not make public the code for its latest GPT 4 language model, "breaking the original contract," Musk's lawyers allege in the complaint. Elon Musk demands that G PT 4 be excluded from the license granted by OpenAI to Microsoft.
