According to Beating, OpenAI sent emails to over 8,000 developers who signed up for the GPT-5.5 offline event in San Francisco, granting them a 10x increase in Codex rate limits effective immediately through June 5. All applicants receive the reward regardless of whether they received an event invitation.
The event, scheduled for May 5 at 5:55 p.m. PT in San Francisco, filled to capacity within 24 hours of opening registrations. The one-month high-usage window allows developers to significantly increase their frequency of using GPT-5.5 for prototyping, debugging, and deployment.
