OpenAI's new Codex agent is essentially a vibe-coding environment based on a ChatGPT-like comment interface. As much as the vibe-coding idea seems like a meme for wannabe cool-kid coders, the new Codex agent is impressive as heck.

You interact with Codex through the ChatGPT interface.; Codex can read and edit files, run commands like test harnesses and linters, and give logs and test outputs.

OpenAI has launched an AI agent in ChatGPT, Codex, that can handle multiple software engineering tasks on behalf of users simultaneously.
