In a significant legal and public relations battle, OpenAI has responded to a lawsuit filed by Elon Musk, its co-founder, over the use of GPT-4 for profit maximization rather than for the benefit of humanity. OpenAI has countered these claims by releasing a series of emails dating back to 2015-16, which they argue demonstrate Musk's support for the company's transition to a for-profit entity. Furthermore, OpenAI alleges that in 2017, Musk sought absolute control over the company, including a merger with Tesla, majority equity, initial board control, and the CEO position by 2018. OpenAI expressed regret over the dispute, emphasizing their admiration for Musk and his initial inspiration for the company's mission. They also intend to dismiss all of Musk's claims in the lawsuit, defending their progress towards their mission without him. OpenAI highlighted that Musk only ever contributed $45 million to the company.
