Codex 3.0 by OpenAI

Codex can now build, test & debug on autopilot

Empowered by the advanced GPT-5.5 architecture, Codex 3.0 by OpenAI has transformed into a sophisticated, true cross-application coding agent. This innovative system is capable of autonomously navigating web browsers, intelligently interacting with complex web applications, generating comprehensive documentation within popular platforms like Microsoft Office and Google Drive, and rigorously testing entire workflows, mimicking the actions of an actual user. Codex intelligently perceives, executes clicks, performs debugging, and iterates on code autonomously, thereby significantly accelerating development cycles and bringing engineers closer to achieving truly reliable, end-to-end automated software builds and deployments.
