Codex CLI 0.148.0 is the substantive release of the period. It adds /export to send a full TUI conversation to Markdown or the clipboard, codex exec fork plus archive and restore from the resume picker, estimated thread credits and cost in /status, Amazon Bedrock Runtime as a built-in provider with GPT-5.6 routing, and asynchronous hooks that can call MCP tools. Sandbox restrictions now fail closed for denied or unreadable paths on Linux and Windows. Off the CLI, Codex crossed 15 million users, the desktop app reached Linux for Ubuntu, Debian and Fedora, and an import path now pulls projects, chats, skills and plugins in from other agents. On pricing, paid usage resets are in testing at roughly $5 to $8 on Plus and up to $80 on the $200 Pro plan. Check /status for your own credit position this week.
Codex CLI
OpenAI Codex CLI v0.148.0 adds /export to Markdown, codex exec fork, and cost in /status
- August 18: v0.148.0 exports complete TUI conversations to Markdown via /export, adds codex exec fork with archive and restore from the resume picker, shows estimated thread credits or cost in /status and terminal titles, adds Amazon Bedrock Runtime as a built-in provider with AWS profile, region and GPT-5.6 routing, and lets hooks run asynchronously and invoke MCP tools.
- Sandbox restrictions now fail closed for denied or unreadable paths across Linux and Windows.
Editor’s read: The fail-closed sandbox change is the one to read carefully. If your workflow depended on a denied path silently passing through, it will now stop.
