Lawyers for Elon Musk on Tuesday moved to dismiss the billionaire’s lawsuit against OpenAI and CEO Sam Altman, ending a months-long legal battle between co-founders of the artificial intelligence startup.

Musk — who co-founded OpenAI in 2015 — sued the company in March, accusing the ChatGPT maker of abandoning its original, nonprofit mission by reserving some of its most advanced AI technology for private customers. The lawsuit had sought a jury trial and for the company, Altman and co-founder and president Greg Brockman to pay back any profit they received from the business.
