Eligible Plus and Pro users gain rate-limit reset banking, including a launch reset and referral rewards for new users.

Changed

  • Codex updates
  • We’ve made several Codex updates, including:
  • Eligible Plus and Pro users now have rate-limit reset banking, including one free reset at launch and the ability to send referral invitations form within the Codex app. When an eligible recipient sends their first Codex message, both people receive a banked rate-limit reset. Banked resets are usable for 30 days after they are granted. Learn more in Invite friends and coworkers and review the current terms.
  • This release also adds Developer mode for Browser use in Chrome and the Codex in-app browser. Developer mode gives Codex controlled Chrome DevTools Protocol access so it can profile JavaScript, inspect console output and network traffic, review page state such as the DOM and applied styles, and diagnose live browser issues. The feature is off by default - users can toggle the feature from Codex app settings.
  • Other changes in this release include the /init command for generating an AGENTS.md project-instructions scaffold, customizable macOS Dock icons, an Unread chats section in the command menu, and clearer usage-limit errors with plan and workspace guidance, including reset timing when available.
