OpenAI to retire older models including Codex variants July 23

By PulseAugur Editorial · [1 sources] ·

Developers using these models, such as GPT-5.2 Codex, must migrate their production configurations and CI scripts to newer models like GPT-5.5. This transition requires more than a simple find-and-replace, as the replacement models have different performance, pricing, and potentially architectural characteristics, necessitating thorough testing and cost analysis.
