As of June 26, per Releasebot, OpenAI removed GPT-4.5 from ChatGPT, migrating existing conversations to GPT-5.5, and rolled Codex Remote to general availability on all plans. You can now start or resume coding work on a connected Mac or Windows host directly from the mobile app. Kicking off a refactor from your phone and reviewing it later is a genuinely different workflow. The GPT-4.5 retirement is a reminder to never hardcode a model name you don't control.
