1. Computer Use: Beyond the Terminal, Into Desktop Apps
Codex now breaks free from terminal limitations—it can interact with your entire desktop. Authorize it, and it gains the ability to view your screen, click UI elements, and type with its own cursor.
Practical Example: Figma to Tailwind Workflow
Suppose you need to extract color values from a Figma design and add them to your Tailwind config. Codex handles this end-to-end:
Task: Extract color values from the Figma file "UI Kit.fig" and write them into tailwind.config.js.Codex will open Figma, locate the design file, screenshot the color palette section, identify hex codes via OCR, and generate the Tailwind config.
2. In-Browser Comment Commands: Talk to Web Pages Directly
Codex introduces a browser-based comment system to manipulate web DOM—no API knowledge needed. Select any element, add a comment describing the change, and Codex automatically updates the element's CSS. This works like Google Docs comments but for web UIs.
3. Automations: Long-Term Task Management
Codex's Automations let you set up scheduled, recurring tasks that run across days or weeks. For example, set up a daily check for new performance-related issues in a GitHub repo. Codex will run daily, fetch new issues, and generate a structured report with problem summaries, reproduction steps, and fix suggestions.
4. Pets: Interactive Status Indicators
Codex's Pets are virtual companions that float on your screen, showing real-time task status. Summon a pet with /slash pet (choose from 8 built-in options or create custom ones with /slash hatch). The pet's animations indicate what Codex is doing.
5. Mobile Remote Control (ChatGPT App Integration)
Codex now integrates with the ChatGPT mobile app, letting you remote-control tasks on your Mac from anywhere. Start a long-running task on your Mac, leave your desk, and check progress, approve intermediate steps, or view diffs from your phone.
6. 90+ New Plugins: One-Click Integrations
Codex now supports 90+ plugins for tools including Atlassian Rovo (Jira management), CircleCI (CI/CD pipelines), CodeRabbit (code review automation), and Microsoft Suite (Excel, Word, PowerPoint).
7. GPT-5.5: Faster, Cheaper, and More Powerful
Under the hood, Codex now runs on GPT-5.5, which is faster (optimized for NVIDIA GB200/GB300 NVL72 hardware), cheaper (uses fewer tokens for the same tasks compared to previous models), and more capable at long-term tasks and complex logic.
8. Skill Synergy: Codex + Claude Code
Many developers now use Codex and Claude Code together: Codex for fast daily coding (keystrokes, UI tweaks, long tasks) and Claude Code for high-stakes work (critical commits, code reviews, complex refactoring).
Example Workflow: Use Codex to draft a new feature's UI components quickly. Switch to Claude Code to refactor for performance and add unit tests. Use Codex's Automations to monitor the feature's GitHub issues post-deployment.
Conclusion: Codex as Your Digital Coworker
Codex has evolved into a full-fledged digital coworker—one that interacts with your desktop, manages long-term tasks, and even keeps you company with virtual pets. Whether you're automating workflows, tweaking UIs, or collaborating remotely, Codex's new features make it an indispensable tool for modern developers.

Frequently Asked Questions
Is Codex's Computer Use feature safe?
Codex's Computer Use requires explicit authorization and you must grant it permission to view your screen and control your desktop. It operates with full transparency—you can see every action it takes. Use it with caution, especially on sensitive data, and only grant access to trusted instances.
What is the cost of GPT-5.5 compared to GPT-4?
GPT-5.5 is significantly more cost-efficient than GPT-4. For a task that used 1,000 tokens with GPT-4, GPT-5.5 might use only 700 tokens, reducing costs by approximately 30%. Additionally, it's faster and better optimized for modern NVIDIA hardware.
Can I use Codex without an internet connection?
Codex requires an internet connection for most features, including GPT-5.5 model access, plugin integrations, and remote control via the ChatGPT app. Some local automation features may work with limited functionality offline, but the core AI capabilities depend on cloud connectivity.
