OpenAI Doubles Codex Limits and Merges Interfaces After Protests

In response to user backlash over reduced benefits, OpenAI has reversed its plan to cut Pro tier limits, instead doubling the usage quotas for ChatGPT Pro and Business Premium users across Work and Codex features. These changes take effect immediately for existing subscribers.

Architecturally, OpenAI is merging interfaces and billing models. Starting in December, Plus, Pro, and Business plans will share a unified token quota pool between ChatGPT and Codex, replacing separate message-based limits. The 'Chat' and 'Work' interfaces are also being consolidated, with agent capabilities integrated into the main experience. While instant chat remains free of quota consumption, high-speed modes like Fast (2.5x cost) and Ultrafast (8x cost) significantly impact remaining balances.

This shift signals a move toward precise token-based metering to balance computational constraints with developer needs. Although OpenAI claims minimal impact for most users, heavy Codex developers must adapt their workflows to account for shared token pools and varying model consumption rates.
