Rakuten doubles issue-fix speed using Codex

AI Impact Summary

Rakuten is reportedly doubling the speed of issue resolution by using Codex to assist coding and debugging tasks. This suggests Codex is integrated into their development workflow (likely via IDE or CI/PR tooling) to generate patches, tests, and debugging scripts. For technical teams, expect higher patch throughput and faster triage, but maintain code review and governance to prevent AI-generated defects from skewing quality metrics.
