Feature Request: Make custom instructions modifiable mid-conversation

Allowing custom instructions to be modified mid-conversation would give so much flexibility, enabling controlled persistent changes in the way the assistant interacts while still retaining previous messages.

Share the chat and copy the link. Change your custom instruction. Follow the share link. Choose “continue conversation”. You get the previous responses but free of the custom instructions that made them.

A shared chat doesn’t share the custom instructions (which would be useful for sharing new “modes” with others).


This is very helpful thank you. I still think it would be a useful feature, for instance if we want to do this in private mode with history disabled and the chat can’t be shared. I like the idea of including custom instructions in shared chat too.
