什么是 Codex？

Virgin Atlantic used Codex to launch its new mobile app before the high-risk Christmas rush, achieving zero P1 defects and near-full test coverage, while accelerating legacy refactoring by up to 80% and enabling non-engineers to build data apps in hours.

OpenAI built a sandbox for Codex on Windows using dual local users and restricted tokens, solving the lack of native process isolation and enabling secure default execution.

OpenAI has been recognized as a Leader in the Gartner® Magic Quadrant™ for Enterprise AI Coding Agents, driven by Codex’s support for 4M+ weekly users, GPT-5.5 integration, enhanced tool use, and enterprise-grade governance capabilities.

Since GPT-5.5's launch, Codex has gained traction among engineers due to generous limits and strong performance, while Anthropic’s new policy ties API credits to subscription value, sparking debate over rising costs for programmatic use.

Frontier enterprises are compounding their AI advantage through deeper, broader adoption—especially in agentic workflows and complex task execution—outpacing peers significantly.
