Codex IDE
https://developers.openai.com/codex/ide
OpenAI has once again changed what is called Codex. It is now not only the old model and a new agent in CLI and ChatGPT, it is also an IDE extension (VSCode, Cursor, and Windsurf).

From it, you can both modify code locally and send tasks to the cloud. It works on Mac and Linux. Windows support is still experimental.

A response to fixed pricing plans in Claude Code. The main thing is that Codex supports paid ChatGPT plans (except Enterprise or Edu, but that's for now), which many people have.
Plus offers 30-150 messages per 5 hours, Pro offers 300-1500.
