FAQs About Custom Instructions
🔸 What’s the benefit? It helps ChatGPT align more closely with how you communicate or the kind of help you need—whether it’s writing, coding, planning, or just chatting.
🔸 Can I change my instructions later? Absolutely! Just update them anytime. However, changes will only apply to future chats—not ones already in progress.
🔸 Is there a character limit? Yes, each field allows up to 1500 characters. That’s plenty of space to get detailed without overwhelming the system.
🔸 Are my instructions private? Yes. Your instructions are part of your account and aren’t visible to others—even if you share a conversation link.

If you delete your OpenAI account, these instructions are automatically deleted as well within 30 days.
