Hello everyone! 🤩 We’ve been excitedly following developments in the world of AI and software for a long time. On February 2, 2026, news came from OpenAI that will shake up developers (in a good way, of course! 😉). Introducing: The OpenAI Codex App!

The era of assistants that only complete code is ending; next up is the era of agentic coding. OpenAI announced the native Codex app for macOS to support this vision. Let’s take a closer look together at what this new app offers and how it might change our development habits. 👇🏻

Codex: Not Just Writing Code, Getting Work Done 🤖

You might remember Codex from its initial release in April 2025. A lot of water has flowed under the bridge since then. Models are no longer just completing functions; they can manage complex, long-running tasks from end to end.

The new Codex app answers exactly this need. OpenAI defines it as a "command center for agents." So we are no longer stuck in a single chat window; we are getting an interface where we can work with multiple agents simultaneously on different projects.

Parallel Agentic Coding with OpenAI Codex With the Codex app, multiple agents can work in parallel in different threads. While you develop the main project on one side, another agent can handle a different task in the background! 🚀

Go Beyond Limits with "Skills" 🛠️

One of Codex’s biggest innovations is the Skills system. Codex is no longer limited to just producing code; it transforms into an agent that can "get work done" on your computer using code.

Thanks to Skills, Codex can:

• Gather and synthesize information,
• Solve problems,
• Read and write documents.

For example, in an internal OpenAI demo, Codex was asked to make a racing game. Codex used its image generation skill to prepare the game’s graphics and its web game development skill to write the code. It even took on the role of "QA tester" and tested the game! 🤯 Working independently by spending 7 million tokens with a single prompt is truly impressive.

Automations: Heroes of the Background ⚙️

Who among us isn’t tired of boring, repetitive tasks every day? Scanning bug reports, preparing release notes, checking CI errors... The Automations feature in the Codex app allows you to schedule these tasks and run them in the background.

When the job is done, the results fall into a "review queue." So when you grab your morning coffee and sit at the computer, you can see that those boring reports are ready. I think it’s a great time saver! ☕️

Choose Your Personality: Serious or Friendly? 🎭

Every developer’s working style is different. Some want "short and concise" answers, while others like working with a more talkative assistant. Codex now leaves this choice to us:

• Pragmatic Style: Short, clear, and result-oriented.
• Empathetic Style: More talkative and interactive.

You can easily change this with the /personality command. I’ll probably change it according to my mood, how about you? 😄

Security and Models 🔒

I can almost hear you saying, "What about security?" OpenAI designed the Codex app with security first. The app runs in a sandbox, just like the CLI version. By default, it can only access files in the folder it is working in, and it asks for your permission for sensitive operations (like network access).

On the model side, the GPT-5.2-Codex model is used. This model is specially optimized for long-running engineering tasks. OpenAI states that they will take the model’s capabilities even further as developer usage increases.

Codex AGENTS.md: Define Project Standards and Rules By adding an AGENTS.md file to your project root, you can teach Codex project-specific rules. This file ensures Codex remembers your code style, test standards, and architectural preferences every time. It’s like giving an "Onboarding" document to a new developer joining the team! 📄

Access and Pricing 💸

Let’s get to the most important issue: How will we access this beauty?

• Compatibility: The Codex app has currently only been released for macOS users. Windows users will have to wait a bit longer, but it is stated that work is ongoing. Windows users continue with the CLI or IDE extension for now!
• Price: Included in ChatGPT Plus, Pro, Business, Enterprise, and Edu subscriptions! Plus, Codex rate limits have been doubled for users on these plans! 🚀
• Good News: For a limited time, ChatGPT Free and Go users will also be able to experience Codex! 🎉

Frequently Asked Questions (FAQ) ❓

Here are answers to the most trending questions about Codex.

Is OpenAI Codex App Available for Windows?

Currently, the OpenAI Codex App is only available for macOS. However, Windows users can still access Codex capabilities via the Codex CLI or the VS Code extension. Work on the Windows desktop app is ongoing.

Is Codex App Free?

Yes, for a limited time, ChatGPT Free and Go users can also experience the Codex app without extra cost. It is included in Plus, Pro, Business, and Edu subscriptions.

What Does "Build Faster with Codex" Mean?

"Build Faster with Codex" highlights how the agentic nature of Codex accelerates software development. By using multi-agent workflows, automations, and skills, developers can ship code faster than traditional methods allowed.

Future Outlook

The Codex app seems to be an important step carrying the coding experience with AI from "copilot" to "application management system." Especially multi-agent support and automation capabilities have the potential to save time in large projects.
