Probably for the ease of coding extensions — which strikes me as outdated thinking: if it’s open source and you’re outsourcing the coding to LLMs, why not use a compiled, safe language?

There’s an interesting counter example for DeepSeek called CodeWhale, though:

Also isn't OpenAI's Codex written in Rust?

    I don’t think so. The ChatGPT app was, which is the “Classic” app now. The Codex app that they’re carrying forward is an Electron app and if you forget to quit it before you walk away it’ll make even your M5 Max unresponsive eventually. Sad days.

      Sorry, I meant the Codex CLI harness. I don't understand why OpenAI decided to start using the "Codex" name for everything.

    I don’t think so it’s an npm package iirc

      Reasonix (which has been seemingly the most recommended harness for using DeepSeek, as it is designed around maximizing caching in DeepSeek) is now a Go app, but still installed via npm. Which feels ugly, but I guess everyone has npm already, and it handles binaries, so I guess it's a reasonable choice.
