Codex can now build, test & debug on autopilot

Powered by GPT-5.5, Codex 3.0 by OpenAI has advanced to become a sophisticated cross-application coding agent, capable of seamlessly navigating web browsers, interacting dynamically with various web applications, generating comprehensive documentation within Microsoft Office and Google Drive, and rigorously testing complex workflows just like a human user. This intelligent agent autonomously observes, clicks, debugs, and iterates, providing developers with an unprecedented level of automation that leads to more reliable, end-to-end automated software builds and deployments.
