OpenAI has begun emailing over 8,000 developers who applied for its invite-only GPT-5.5 party with a surprise gift: a tenfold increase in Codex rate limits on their personal ChatGPT accounts. This boost, which will last until June 5, is not limited to those who received invitations to the party, but is available to all who applied, regardless of whether they were accepted, waitlisted, or turned away.
Increased Access to Codex
The increase in Codex rate limits has significant implications for developers. Codex, OpenAI's AI-powered coding agent, operates under daily usage caps that vary by subscription tier. With a tenfold increase in these caps, developers will have more room to prototype, debug, and ship code using GPT-5.5, which OpenAI claims matches GPT-5.4's per-token latency while performing at a higher level of intelligence and using significantly fewer tokens to complete tasks.
The 31-day window of expanded access is generous enough to reshape habits and turn a curious trial into a daily dependency. By flooding thousands of developers with expanded access during a critical adoption period, OpenAI is effectively subsidizing the kind of deep, sustained usage that turns Codex into a daily workflow. It is a bet that once developers experience Codex at full throttle, they won't want to go back, and that when the limits reset on June 5, a meaningful number will upgrade their subscriptions to preserve the workflow they've built.
Developer Community Response
The developer community has responded with a mix of glee and regret to the news of the Codex rate limit boost. Some developers have expressed their excitement and gratitude, while others have kicked themselves for not signing up for the GPT-5.5 party. Several users have raised a question about whether the boost stacks with the existing Pro $200 tier's 20x multiplier, with one user reporting that OpenAI support said no, and that users get whichever limit is higher, not a combined total.
The GPT-5.5 Party
The rate limit gift is a sidecar to the main event: the invite-only GPT-5.5 party, which is running on May 5 from 5:55 p.m. to 8:55 p.m. PDT at an undisclosed San Francisco venue. OpenAI has billed the evening as a low-key meetup with Sam Altman and the team behind GPT-5.5, promising food, drinks, community, giveaways, and swag. In a detail that doubles as a product demo, Altman revealed that GPT-5.5 itself planned the party, proposing the date, suggesting that human developers give the toasts, and recommending setting up a suggestion box for the next-generation model.
As the month of supercharged Codex access comes to a close, it will be interesting to see how developers respond to the increased limits and whether they will choose to upgrade their subscriptions to preserve their workflow. With the AI landscape evolving rapidly, OpenAI's move to subsidize deep, sustained usage of Codex is a strategic bet on the future of AI-powered coding agents.
AI summary
OpenAI, GPT-5.5 partisine katılan geliştiricilere Codex rate limitlerini 10 katına çıkararak 5 Haziran'a kadar yararlanmalarını sağladı. Geliştiriciler, bu yeni olanaklardan yararlanarak projelerini daha hızlı şekilde tamamlayabilirler.
