OpenAI Codex

Overview

OpenAI Codex is a cloud-based AI coding agent developed by OpenAI that can autonomously complete software engineering tasks such as writing code, fixing bugs, running tests, and navigating codebases. It operates in isolated, sandboxed cloud environments and can handle multiple tasks in parallel, making it suitable for teams looking to accelerate development workflows. Codex is designed for professional developers and engineering teams who want to delegate complex, multi-step coding tasks to an AI agent.
