Cursor chats can fill their context even after a restart
In Cursor, a long-running chat can reach 85% . Starting a new chat does not always create much more room if the model is immediately asked to scan the project and read .
After that setup, the new chat can already reach 75% within a few minutes. The real question is not only whether the chat is old or new, but whether the model has a clean set of information for the task.
If the is similar, a new chat is not automatically safer or less likely to make wrong guesses. Still, a new chat may help if the old one contains outdated decisions, failed attempts, or extra discussion that no longer matters.
