OpenAI ChatGPT Update Version June 11, 2026

Codex updates add Browser use Developer mode, rate-limit reset banking for eligible Plus and Pro users, and new workflow tools like `/init` for AGENTS.md scaffolding. The release also improves macOS and chat navigation plus usage-limit messaging.

• Clearer usage-limit errors with plan, workspace, and reset-timing guidance.
• Improved browser troubleshooting through Developer mode access to DevTools data such as console output, network traffic, DOM state, and applied styles.

• Developer mode for Browser use in Chrome and the Codex in-app browser, with controlled Chrome DevTools Protocol access for profiling and live issue diagnosis.
• Rate-limit reset banking for eligible Plus and Pro users, including one free reset at launch and banked resets from referral invitations.
• The /init command for generating an AGENTS.md project-instructions scaffold.
• Customizable macOS Dock icons.
• An Unread chats section in the command menu.

• Developer mode is off by default and must be enabled from Codex app settings.
• Banked rate-limit resets are usable for 30 days after they are granted.
• Eligible recipients who send their first Codex message trigger a banked reset for both people.
