OpenAI Resets Codex Rate Limits to Boost GPT-5.5 Development

Apr 28, 2026

OpenAI performed a manual reset of Codex rate limits for all paid plans, including the recently launched ChatGPT Pro $100 tier. This update clears usage quotas for agentic coding (AI that autonomously writes and iterates on code), allowing developers to build with GPT-5.5 without waiting for standard refresh cycles.

This tactical reset follows a pattern of celebratory usage boosts, mirroring the previous limit refresh when the platform reached three million users. By removing infrastructure bottlenecks, OpenAI is incentivizing engagement with its upgraded GPT-5.5 agent as it competes for developer mindshare against increasingly capable proprietary coding assistants.

If you are on a Plus, Pro, or Enterprise plan, your usage limits have already been restored. This allows for immediate, high-volume testing of workflows like UI automation or complex repository edits. The team confirmed another reset is planned shortly to mark the five million user milestone.

Don't just reset Codex rate limits for fun, it costs money. Don't just reset Codex rate limits for fun, it costs money. ... but the vibes are good ... I have reset Codex rate limits for ALL paid plans to celebrate a good week and allow everyone to build more with GPT-5.5. Enjoy

Still wondering? A few quick answers below.

The rate limit reset applies to all users on OpenAI's paid subscription plans. This includes subscribers on the Plus, Pro, and Enterprise tiers. Users on these plans saw their usage quotas for the Codex agentic coding platform immediately restored to full capacity, allowing them to continue development tasks without waiting for their standard refresh period.

The current version of Codex is powered by the GPT-5.5 model. This model enables agentic coding capabilities, allowing the system to autonomously navigate codebases, perform multi-step edits, and use computer interfaces. The recent rate limit reset was specifically designed to allow developers to build more extensively with this latest model iteration across their engineering workflows.

OpenAI performed the manual reset to celebrate a successful week of growth and to encourage developers to build more with the GPT-5.5 model. These celebratory resets are used as a tactical incentive for the developer community, clearing infrastructure bottlenecks and maintaining momentum as the platform scales toward its next major user milestone.

OpenAI has confirmed that another manual reset of Codex rate limits will occur shortly to celebrate reaching five million users. While the exact date depends on user growth, the company uses these milestones as triggers to provide additional compute capacity to its paid user base, following a pattern established during previous growth markers.

Codex is available through several paid tiers, including the standard Plus plan and a specialized 100 dollar per month Pro tier designed for heavy usage. The Pro tier currently offers five times the allowance of the Plus plan. Enterprise and Education users have different scaling limits where usage typically grows based on allocated credits rather than fixed weekly caps.
