Quick answer
OpenAI released Codex CLI 0.153.0 on September 3. The stable update adds commands for listing, installing, and removing plugins from remote marketplaces; Vim undo and redo in the composer; an option to disable automatic recaps; richer terminal history; and earlier usage warnings for Plus and Team users. It also reconnects TUI sessions after an app-server interruption, preserves Guardian review history, scopes remembered MCP approvals to the selected app account, and introduces an off-by-default experimental context-management mode. This is a Codex tooling release, not a new AI model or a Chat AI availability update.
Codex CLI 0.153 expands plugin and terminal workflows
The stable 0.153.0 release lets the plugin CLI list, install, and remove plugins from remote marketplaces. The terminal interface also gains Vim-style undo with u and redo with Ctrl+R, preserves pasted content and attachments in draft history, and shows complete patches, background-terminal input, and individual completed commands in its history. These are client and workflow changes rather than a model upgrade.

Interrupted TUI sessions can reconnect without silently sending queued work
OpenAI says Codex now reconnects a terminal session when its external app-server connection drops. Drafts and transcripts are preserved, while submissions whose state is uncertain or that remain queued stay paused for review. That distinction matters after a network or process interruption: users can inspect the recovered session before deciding whether to resend or continue.

Remembered MCP approvals are now tied to the selected app account
The release scopes remembered MCP tool approvals to the app account selected for that connection. This reduces the chance that an approval remembered for one linked account is treated as applicable to another account. OpenAI also fixed startup of MCP servers that use relative executable paths on macOS. Teams with multiple accounts or locally configured servers should verify both account selection and server startup after upgrading.

Guardian review behavior now follows the active approval mode more closely
In Full Access mode, confirmation-only actions no longer run a separate Guardian review. In User approval mode, background Guardian scoring and prewarming are skipped. The release notes say sensitive-action checks and requests for user input keep their existing handling, so these changes should not be read as removing those boundaries. Guardian review history also survives compaction, restarts, and user-created forks while respecting rollback and subagent isolation boundaries.

Recaps, usage warnings, and history get practical controls
Users can set tui.auto_recap to false to stop automatic recaps while retaining the manual /recap command. Plus and Team users also receive an earlier warning when less than half of their allowance remains in an approximately five-hour usage window. The warning describes remaining allowance; it does not change the plan limit. Teams that depend on automatic summaries should check their configuration before turning recaps off.

Experimental context management remains disabled by default
Version 0.153 adds features.context_management.experimental_mode. When explicitly enabled for eligible ChatGPT Plus, Pro, or Pro Lite sessions using the Codex backend, it activates token-budget context, history notes, and the new_context tool. API-key sessions, custom providers, and temporary structured threads are excluded. Because the setting is experimental and off by default, users should not assume those behaviors are active after a routine upgrade.

Upgrade with a short plugin, reconnect, and permission check
After installing the release, list configured plugin marketplaces and confirm that a test plugin can be installed and removed from the intended source. Then interrupt a non-critical TUI session to confirm its draft and transcript return without an uncertain request being sent automatically. If you use multiple linked MCP accounts, verify that approvals stay with the selected account. Finally, confirm recap and usage-warning behavior matches your configuration. These are practical checks derived from the release notes, not an OpenAI certification procedure.

Codex CLI 0.153 is not a new model in Chat AI
Codex CLI 0.153.0 updates OpenAI's coding-agent client and related app-server behavior. It does not announce a new OpenAI model or add a model to Chat AI. Chat AI availability is therefore marked not applicable for this article.
