When should I start a new chat instead of continuing one?
Signs the thread has run its course
Replies may start ignoring recent instructions, or they may bring back details from much earlier. Long threads can also make the model mix up names, numbers or versions. If you notice either problem, it is usually time to reset.
Watch for answers that cite claims you never made or mix up two projects. Those are strong signs that the thread has become too tangled to trust.
Carrying context into a fresh chat
Write a short summary of the decisions, facts and goals so far. Paste that summary at the top of the new chat along with your next request. A clean summary often beats dragging the whole history forward.
Keeping related work together
If you are still on the same project, stay in the thread so the model keeps track of early choices. Use a separate chat for unrelated tasks, such as a recipe question after a coding session. Naming your chats also helps you find a useful thread later.
If you switch projects often, consider starting a fresh chat each time instead of mixing topics in one long thread. Keep the summary under a few hundred words so it stays easy to read.
Common mistakes
- Carrying an unrelated question into a long project thread.
- Starting over without saving the facts you already worked out.
