OpenAI CEO Sam Altman Welcomes Elon Musk to Upcoming GPT-5.5 Event

ChatGPT maker OpenAI’s CEO, Sam Altman, has no problem if Elon Musk shows up uninvited to the company’s GPT-5.5 private event. Responding to a post on microblogging site X that joked about the world’s richest man “crashing” the event, Altman said that Musk would be welcome at the invite-only gathering.

Altman’s reply comes after an X user named Andrew Curran wrote, “Elon's going to show up uninvited to this GPT-5.5 party like the witch in 'Sleeping Beauty' and deliver a powerful curse.” Altman replied, “He can come if he wants… world needs more love.” The exchange has drawn attention online as discussions around OpenAI and its upcoming GPT-5.5 event continue to gain traction.

These comments come as Musk faces Altman and other OpenAI executives in one of the biggest courtroom fights in Silicon Valley history. The trial is taking place amid Musk's lawsuit against OpenAI and its CEO, Sam Altman, for allegedly betraying the organisation's founding nonprofit mission and becoming a "profit-driven venture" for Microsoft.

The dispute between Sam Altman and Elon Musk dates back to a 2015 email that led to the creation of OpenAI, a nonprofit focused on developing AI for public benefit. Musk was one of the founders who provided funding for the startup and hired talent, yet by 2017, he began to disagree with the company's direction, and in 2018, he left the board.

After that, OpenAI started working on ChatGPT, obtained major investments from Microsoft, and moved towards a cap-profit model. In 2024, Musk filed a lawsuit stating that OpenAI and its executives misled him about remaining a non-profit and had actually switched to a profit model. He demanded that the leadership be changed, that the restructuring be undone, and that he receive compensation from the non-profit, which has now become a ‘for-profit.’

OpenAI claims that Musk knew about their plans to become for-profit and left due to failure to get any power over the company. Throughout the trial, numerous emails and texts have been made public, demonstrating the disagreement and personal conflicts of that time. This lawsuit may affect OpenAI's future IPOs and views on the governance of artificial intelligence. The witnesses testify for both sides and include top executives and other relevant industry players.
