Patna: OpenAI has launched a new desktop application called Codex, created to make coding simpler and faster for developers. The app is designed especially for macOS users and brings powerful AI tools directly onto the computer screen. Instead of moving between different websites, code editors and terminals, programmers can now do everything in one place. With this launch, OpenAI hopes to change the way people write software by letting artificial intelligence handle many tasks at the same time.
What makes Codex special is that it uses multiple AI agents. Each agent works in its own thread, meaning several tasks can run together without confusion. For example, one AI can write new code, another can fix errors, and a third can review changes — all at once. Earlier AI tools could only handle one job at a time, which slowed developers down. Codex removes this limit and allows work to move much faster.
The app is powered by OpenAI’s cloud-based Codex system, which was introduced in April 2025. It is trained on large amounts of programming data and understands instructions written in simple English. Developers can ask it to write code, test programs, fix bugs, or add new features. It supports popular languages such as Python, JavaScript and Go, making it useful for many kinds of software projects.
Codex also includes tools that help developers stay organised. Its thread system keeps tasks separate so that changes do not clash with each other. The app also offers diff review, which lets users clearly see what has been changed in the code, and edit it if needed. Another feature, called Skills, allows developers to save templates for common tasks, so the AI can repeat them quickly in the future.
At present, the Codex app is available for macOS devices with Apple Silicon. Users can log in using their ChatGPT account or the OpenAI API. The company has announced that versions for Windows and Linux are coming soon. Many developers believe Codex could greatly change how software is built, turning a single programmer into a small team powered by artificial intelligence.
