OpenAI Boosts Codex Access for Thousands After GPT-5.5 Event Overwhelmed by Demand
OpenAI has granted a 10x increase in Codex usage limits to more than 8,000 developers who applied to its invite-only GPT-5.5 launch event, the company confirmed Monday. The boost, effective immediately through June 5, applies to all applicants — regardless of whether they received an invitation, were waitlisted, or were rejected. The move comes after the company received far more interest than it could accommodate for the physical party.
“We had over 8,000 people express interest in just 24 hours, and while we wish our office was big enough to welcome everyone, we weren’t able to make space for every person who applied,” OpenAI wrote in an email obtained by VentureBeat. “As a small token of appreciation, we’ve 10x’ed your Codex rate limits until June 5th on your personal ChatGPT account.”
CEO Sam Altman previewed the gesture on X shortly before the emails went out. “We are gonna do something nice for everyone who applied for the GPT-5.5 party and that we didn’t have space for,” he wrote. “Hope you enjoy!” The post racked up more than 521,000 views within hours.
Background
The GPT-5.5 event, originally planned as an intimate gathering, was inundated with applicants within 24 hours of its announcement. OpenAI had expected to host only a fraction of the 8,000-plus developers who signed up. The party was designed to showcase the new model, which reportedly matches GPT-5.4’s per-token latency while delivering higher intelligence and requiring significantly fewer tokens for tasks.
Codex, OpenAI’s AI-powered coding agent, is tightly integrated with GPT-5.5. Its daily usage caps vary by subscription tier, and a ten fold expansion now gives developers dramatically more room to prototype, debug, and ship code.
What This Means for Developers
The 31-day window is generous enough to reshape habits. By flooding thousands of developers with expanded access during a critical adoption period, OpenAI is effectively subsidizing deep, sustained usage — turning a curious trial into a daily dependency. “I’m literally not taking my Codex hat off for the month,” one developer declared on X.
Others expressed regret for not applying. “That’s the last time I don’t sign up just because I’m not in SF,” another wrote. The community buzz suggests OpenAI’s bet is working: once developers experience Codex at full throttle, many will likely upgrade their subscriptions to preserve the workflow after June 5.
However, a key question remains unanswered: does the boost stack with the $200 Pro tier’s 20x multiplier? One user reported that OpenAI support said no — users get whichever limit is higher, not a combined total. “The key question isn’t whether the 10x boost is only for party applicants. It’s whether it stacks with Pro,” they wrote. OpenAI has not publicly addressed the stacking issue.
