OpenAI Codex (AI agent)

Codex is an AI coding agent developed by OpenAI and integrated with ChatGPT. Launched as a research preview in May 2025, it is designed to handle software engineering tasks – such as writing features, fixing bugs, and reviewing codebases – autonomously in a cloud environment before returning results for human review. The agent is available through multiple interfaces, including ChatGPT's web app, a command-line interface, a macOS desktop app, and integrations with IDEs such as VS Code, JetBrains, and Xcode. In March 2026, OpenAI introduced Codex Security, an application-security agent designed to identify and propose fixes for software vulnerabilities.

Press coverage described Codex as OpenAI's entry into an increasingly competitive market for AI coding tools, where it competes with products such as Anthropic's similar Claude Code and Cursor. By March 2026, OpenAI reported that Codex had grown to more than 1.6 million weekly active users and was positioning it as a broader enterprise agent platform that could eventually be used for tasks beyond software development.
