## What it is

Codex is OpenAI's coding agent — it runs tasks in the cloud or your terminal, works through issues, writes PRs, and can operate autonomously on a repo.

## Why it's good for vibe coding

Strong at running longer autonomous tasks and turning issues into working pull requests while you do something else.
