Rakuten doubles issue resolution speed with Codex integration

AI Impact Summary

Rakuten has integrated Codex to accelerate issue diagnosis and patching, effectively doubling the speed of fixes. Codex-assisted workflows support faster code search, repro, and patch generation, reducing triage and remediation cycles for developers. The resulting faster turnaround can translate into shorter service downtime and quicker delivery of mitigations, but governance and quality checks should be kept to avoid regression or code drift.
