Sam Altman invites Elon Musk to OpenAI’s GPT-5.5 private event amid ongoing legal dispute

Sam Altman on Friday publicly said Elon Musk could attend OpenAI’s upcoming GPT-5.5 private event. He was responding to a viral post on social media platform X that joked about Musk “crashing” the invite-only gathering.

“He can come if he wants… world needs more love,” Altman wrote in reply to a post by user Andrew Curran, who had referenced Musk appearing uninvited “like the witch in Sleeping Beauty.”



The exchange has drawn significant engagement online, with Altman’s reply garnering thousands of interactions within hours.

The comments come against the backdrop of an escalating legal dispute between Musk and OpenAI. Musk, a cofounder of OpenAI in 2015, has filed a lawsuit alleging the company has deviated from its original non-profit mission. OpenAI has previously disputed these claims.

The GPT-5.5 launch event is expected to take place in San Francisco on May 5, although the company has not formally announced event details.

OpenAI rolled out GPT 5.5 on April 24. The company described it as a “new class of intelligence for real work and powering agents.” It highlighted improvements in areas such as agentic coding, computer-based tasks, knowledge work, and early-stage scientific research.

Altman’s return to frequent posting on X also marks a shift back to a more public-facing communication style reminiscent of earlier “Twitter-era” engagement, as he referenced in a separate post earlier the same day.

“It’s good to be back on Twitter. There is comfort in the skills of a wasted youth,” Altman wrote.


On the sidelines, Elon Musk has spent more than seven hours on the witness stand in a trial that is expected to last a month in federal court in Oakland, California.

Musk argued that the shift of OpenAI from a non-profit to a for-profit company violated the organisation’s founding principles. He is seeking up to $150 billion in damages, though he says any payout would go to OpenAI’s charitable arm.
