OpenAI Codex

OpenAI Codex is a cloud-based coding agent that autonomously handles entire software development tasks. It can write new features, fix bugs, and open pull requests, all within isolated parallel sandboxes. The agent integrates directly with GitHub for seamless code review and collaboration, and includes a CLI companion for command-line workflows. Codex is designed for developers and teams who want to delegate coding tasks to an AI that works in the cloud, accelerating development cycles and reducing manual effort.
