OpenAI launches Codex, a coding agent for software development
OpenAI has released Codex, an agentic coding tool available across its paid ChatGPT plans.
OpenAI has launched Codex, a dedicated coding agent designed to assist with software development tasks. The tool is available to subscribers on ChatGPT Plus, Pro, Business, Edu, and Enterprise plans.
The release marks OpenAI's formal entry into the agentic coding space, where tools like GitHub Copilot, Cursor, and Claude Code have already established footholds. By bundling Codex into its existing paid tiers rather than offering it as a separate product, OpenAI is positioning the agent as a core capability of its platform — potentially reaching millions of existing subscribers without requiring a new purchase decision. For development teams already evaluating AI coding assistants, Codex adds another option from a major foundation model provider, intensifying competition in a market that has become one of the fastest-growing segments in enterprise AI tooling.
