Openai Codex: Revolution in programming with Rust instead of TypeScript!

In the technology sector, a lot is happening and one of the most exciting innovations comes from Openai. The company switched its Codex Cli to Rust from the use of the popular programming languages ​​React and TypeScript. As reports [Security Boulevard] (https://securityboulevard.com/2025/06/openai codex-transitions-t-enhancing-efficiecy-and-power/), this is a strategic step that is primarily intended to improve the safety and performance of the software.

The team behind Codex announced the changeover in a blog post to Github entitled "Codex Cli is going native". Martin Fouad, the responsible developer, led the most important motives for this change. An important point is the liberation of dependencies, since the installation of Node V22+ was previously necessary, which was a hurdle for many users. Rust also opens up new possibilities for native safety bonds that optimize Linux sandboxing while efficiency is increased, since Rust avoids the runtime garrecade collection that often leads to high memory consumption.

advantages of switching to Rust

The advantages of switching to Rust are diverse. The new Codex Cli enables developers to expand their skills in various programming languages, including TypeScript and Python. The performance also speaks for itself: Rust proves to be more efficient than JavaScript on the V8 Engine by Node.js. The implementation is still in development, but the typecript version will continue to be waited until the functionality of the Rust version is comparable. Developers can easily test the new version with the command NPM I -G @Openaai/Codex @native .

Another plus for the Openai Codex Cli is the possibility that it will work locally without code being transferred to the cloud. All Openai models can be called up by the Response API, with the O4-Mini model being used by default. In addition, interesting commands are available, such as Codex “Explain This Codebase to Me” or Codex-APPROVAL-MODE FULL-Auto “Create The Fanciest todo-List App” .

industry trends and outlook

The changeover to Rust is not just an isolated case. More and more companies, including Microsoft, are align their critical applications on Rust. This shows that the trend in the industry is increasingly tends to this programming language. Even the TypeScript compilers and Vite have already switched parts of their systems to Rust. An outlook on the future should not be missing: On November 10, 2025, the online conference Bettercode () Rust will take place, which deals with Rust industrial applications. The program announcement follows in mid -July, and the tickets are available up to this point at a special price.

Finally, it can be said that the changeover of the Openai Codex Cli on Rust sends a strong signal for the future of the software development landscape. With this change, Openai not only shows innovation spirit, but also a good knack in dealing with modern technologies.
