Codex 0.154.0
Codex 0.154.0 adds GPT-6-Astra support, experimental worktree sessions, inline question answering, and a shared Windows background server.
Codex 0.154.0 adds GPT-6-Astra to the model picker and Amazon Bedrock catalogs, alongside changes to how sessions are managed and edited. Full details are in the release notes.
- GPT-6-Astra is now available in the model picker and in Amazon Bedrock catalogs.
- Experimental worktree support lets you create isolated checkouts for new or forked sessions using --worktree or /worktree, then browse and resume them.
- You can answer questions inline while Codex keeps working, using suggested choices or custom text, without losing your main draft.
- Windows sessions can now share a background Codex server, with daemon lifecycle commands and managed updates.
- Vim editing gains an R replace mode with undo and dot-repeat, plus more reliable Escape handling in legacy terminals.
- Copying responses now preserves formatting in rich-text apps, and /copy can copy status output or individual session fields.
The release also fixes several issues: existing sessions now pick up newly installed plugin tools and refresh skills and hooks after external plugin upgrades, MCP connections coordinate OAuth token refreshes instead of replaying rejected tool calls, and remote resume and fork operations preserve saved permissions. The deprecated codex mcp-server entry point has been removed.
