Make it possible to split chat threads in order to boost RAM effectiveness

Hi OpenAI team!

I’d love to suggest a “Split Chat” feature — the ability to fork a conversation into a new thread from a chosen point, optionally carrying over relevant context as a summary. This would make long coding and research sessions easier to manage and reduce lag as threads grow. Bonus points if you can title or link back to the original chat!

Thanks for building such a great tool — this would make it even better.
