The Japanese e-commerce giant Rakuten has deployed OpenAI's Codex to accelerate its software delivery pipeline, cutting the time needed to identify and resolve critical issues by half.
The AI-powered coding agent automates key bottlenecks in Rakuten's development workflow. By handling routine code reviews during the continuous integration and deployment phase, Codex eliminates manual inspection delays that typically bog down teams. The result: issues that once took twice as long to fix now move through the system faster.
Speed isn't the only gain. Rakuten's engineers report improved safety across deployments. Codex catches potential problems in the build process that might otherwise slip through, adding a layer of automated quality control without requiring additional headcount.
The efficiency boost extends to full-stack development cycles. Projects that previously stretched across months now ship in a matter of weeks, freeing engineers to focus on architecture and feature work rather than repetitive debugging and code verification.
Rakuten's adoption signals growing confidence in AI agents for production environments. Unlike chatbots confined to simple Q&A, Codex integrates directly into the development toolchain, making real decisions about code quality and system health. The company's case demonstrates that for organizations willing to integrate AI into core workflows, the productivity multiplier can be substantial.
The move reflects a broader industry trend: companies are moving past AI as a novelty tool and embedding it into the technical infrastructure where it matters most.
