OpenAI describes how Nextdoor engineers are incorporating Codex with GPT-5.5 into their development workflow. The tool is being used to track down hard-to-reproduce defects, which can otherwise consume significant engineering time.
According to the source, Nextdoor also applies Codex to build across multiple platforms. This lets engineers shift attention toward product outcomes rather than getting caught up in routine, low-level implementation details.
