AI models use the context in a conversation to understand each new message. As a chat grows, later requests may require the model to process more previous content, which can increase credit usage.
A short conversation gives the model less context to process. A long conversation may include many earlier messages, even when they are no longer relevant to the current task.
If you switch to an unrelated topic inside a long chat, you may pay for context that does not help the answer. Starting a new chat gives Nora a clean context for the new task and can reduce unnecessary usage.
Start a new conversation when:
Keep using the same conversation when the earlier context is important, such as when refining a document, debugging the same issue, or continuing a multi-step analysis.
If Nora needs the earlier messages to answer well, continue the chat. If it does not, start a new one. This habit keeps conversations easier to manage and helps your credits go further.
