- OpenAI let ChatGPT plan a launch party to celebrate the release of its latest model, 5.5.
- ChatGPT wanted the event to be held on May 5 at 5:55 pm, with its human creators delivering a toast.
- Pics from attendees show an Apple Store-like experience.
OpenAI's invitation to GPT-5.5's launch party said the vibe would be intimate: a "low-key" gathering with CEO Sam Altman, drinks, swag, and a few hundred developers celebrating the company's latest AI model at its San Francisco headquarters.
Instead, it became one of the hottest tickets in tech, with more than 8,000 people scrambling to get into a party that Altman says ChatGPT itself helped plan.
While it remains unclear how many applicants were ultimately offered access to the exclusive event, those who were accepted were quick to tout their status on social media. However, the rejects still got a party favor: OpenAI offered upgraded Codex rate limits to everyone who requested a ticket, granting additional free access to its coding agent.
Inside, photos posted by attendees show the vibe was somewhere between a developer meetup, a Hollywood premiere, and a very expensive social experiment.
OpenAI did not respond to a request for comment from Business Insider.
An invite felt like a golden ticket
