Last Friday, OpenAI introduced a new coding system called Codex, designed to perform complex programming tasks from natural language commands. Codex moves OpenAI into a new cohort of agentic coding tools that is just beginning to take shape.

OpenAI has officially released Codex, its most advanced AI coding assistant so far. The new codex-1 model that powers Codex is fine-tuned on software engineering tasks. This innovative technology will completely change the way that developers think about and work with code.

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.
