Meet the New Codex CLI
5/10TL;DR
Codex CLI has added a full-screen terminal interface, voice-triggered multitasking, remote control from a phone, worktree forking, and in-terminal rendering for Mermaid and LaTeX to streamline software work without leaving the command line.
KEY POINTS
Full-screen terminal interface
The updated Codex CLI now includes a full-screen interface designed for terminal-based workflows. It keeps the input footer visible while users scroll through earlier outputs, making it easier to review work and continue issuing commands without losing context.
Voice mode can launch multiple jobs
A new voice mode allows users to start work conversationally inside the CLI. In one demonstration, three tasks were launched at once across two burrito-themed projects: updating a website background, expanding CLI test coverage for price changes and order confirmation, and generating a Mermaid diagram for the order flow.
Multi-agent task management
The interface includes an agent view showing active tasks in one place. Users can filter, group by status, search, and jump directly into a specific task, avoiding the need to manually track file paths or open multiple terminal windows.
Follow-ups and branching with worktrees
Running tasks can receive follow-up instructions, allowing work to continue iteratively. Users can also fork a conversation into a new worktree, preserving the same context while creating a separate checkout for exploring a different implementation path.
Remote access from a phone
Remote control support lets users reconnect to the same machine and task list from a phone after enabling access on a laptop. That makes it possible to check progress, respond to questions, and monitor ongoing work while away from the keyboard, then return later to see what completed and what still needs input.
Results surface directly in the terminal
Completed changes and test results are surfaced inside the CLI, reducing context switching. In the example shown, the web changes and testing outcomes were available immediately, alongside a preview of the updated demo.
Built-in rendering for diagrams and math
The CLI now renders Mermaid diagrams directly in the terminal, expanding its usefulness for documenting workflows and systems design. LaTeX rendering is also supported, allowing mathematical notation and proofs to display natively in the same environment.
Usage analytics and workflow visibility
New usage analytics provide a view into activity patterns, including top chats, plugins, and skills being used. That adds a measurement layer for users who want to understand how they are interacting with the tool and which features are most active in day-to-day work.
CONCLUSION
The update pushes Codex CLI further toward an all-in-one terminal workspace, combining task orchestration, remote access, and rich rendering without leaving the command line. The broader aim is to make development faster and less disruptive for users who prefer to build entirely inside the terminal.
