Technology | ChatGPT ChatGPT 5.5 Planned Its Own Launch Party It's happening 5/5 at 5:55pm By Kate Seamons withNewser.AI Posted May 4, 2026 8:20 AM CDT Copied Sam Altman is seen through a window during a recess in the trial between Elon Musk and OpenAI held at Dellums Federal Building in Oakland, Calif., on Tuesday, April 28, 2026. (Jessica Christian/San Francisco Chronicle via AP) OpenAI's "smartest model yet" is also a decent party planner. At Stripe's developer conference, OpenAI CEO Sam Altman recounted asking GPT-5.5 how it wanted to celebrate its launch. The model reportedly requested a May 5 event at 5:55pm with a toast delivered by its human creators and a dedicated area where guests could submit ideas for GPT-5.6—feedback it suggested should be fed back into the system. "We're going to do it," Altman said, calling the exchange "a strange thing," per Business Insider. On Friday, AI writer Andrew Curran quipped on X that "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 responded with an invite of sorts: "he can come if he wants. world needs more love." The two are currently ensnared in a court battle, with Musk accusing Altman of reneging on the original plan to keep OpenAI as a nonprofit research lab. Both were founding co-chairs of the entity about a decade ago, and Musk is seeking about $150 billion in damages, with the money to go back to OpenAI's nonprofit.
