GPT-5.5 Planned Its Own Party: Elon Musk Also Invited

GPT-5.5 Planned Its Own Party: Elon Musk Also Invited

OpenAI CEO Sam Altman shared a striking anecdote about the company's newest artificial intelligence model, GPT-5.5. Speaking during a conversation with Stripe CEO Patrick Collison at the Stripe Sessions event, Altman said he asked the model how it would like to host its own launch event and that they would implement the resulting plan. Altman also invited Elon Musk.

GPT-5.5 Planned Its Own Party

According to Altman, GPT-5.5 proposed a highly detailed organizational flow for its launch event. The model requested the event to be held on May 5th, with speeches kept short, and specifically asked for the engineers who developed the model to speak on stage. Even more interestingly, GPT-5.5 suggested a speech be given on its behalf at the event but refused to speak itself.

The launch event was planned to be by invitation only. Scheduled for May 5th at 17:55 (03:55 TSİ, the next day) at OpenAI's headquarters in San Francisco, the event is also employing an unconventional method for guest selection. Altman shared an application form via the social media platform X, collecting applications, and announced that OpenAI's coding agent, Codex, would play a role in selecting participants from these applications.

The company also offered to cover flight and accommodation expenses for participants selected from outside the San Francisco Bay Area. However, due to intense interest, the registration process closed quickly. Altman stated that they received far more applications than expected and would plan larger events for future launches.

Elon Musk Also Invited

The event garnered attention not only for its organizational structure but also for a notable invitation from Altman. Despite their ongoing legal disputes, Altman extended an open invitation to Elon Musk, stating, "He can come if he wants... the world needs more love."

Altman's statement came immediately after a warning from the judge presiding over their case. U.S. District Judge Yvonne Gonzalez Rogers, who is overseeing the ongoing lawsuit, had urged both parties to refrain from using social media in a way that escalates tensions outside of court proceedings.

What Does GPT-5.5 Offer?

Introduced on April 23rd, GPT-5.5 is positioned as OpenAI's latest flagship model and is available to paid ChatGPT and Codex subscribers. According to the company's statement, the model can perform multi-step and complex tasks more effectively with less user guidance compared to previous versions.

OpenAI co-founder Greg Brockman describes GPT-5.5 as a structure that will form the foundation of computer-based work in the future. The model achieved an 82.7% success rate in the Terminal-Bench 2.0 test, which measures software development performance. Furthermore, with a context window exceeding 1 million tokens, it can work with much longer and more complex datasets.
