Overview

At DevDay on September 29, 2026, OpenAI refreshed Codex CLI with voice-driven task control: a /voice command starts a spoken session so developers can kick off or steer work and hear audio responses. A new /agents view lists concurrent tasks, shows progress, and lets users switch between them without separate terminal windows. OpenAI also introduced persistent, reusable cloud development environments accessible from any device, giving teams a shared workspace with approved settings and permissions instead of a fresh sandbox per task, plus improved prompt editing, session resumption, and git worktree support. A companion code review feature integrates Codex into the ChatGPT desktop app, letting developers examine change summaries and run automatic reviews while away, with feedback shareable to GitHub or GitLab. The refreshed CLI is available across all ChatGPT plans.
