OpenAI just rolled out a small but really helpful change.
Until now, if you updated your ChatGPT personality or custom instructions, those changes only applied to new conversations.
Starting today, your updates are applied immediately across all chats — even existing ones! 🎉
That means your tone, preferences, and custom setup stay consistent everywhere… no need to start a new thread just to make it work.
👉 Have you tested this yet?
Do you use custom instructions to make ChatGPT sound more like you?
