Abstract
A chat history between a user and a machine learning model is preserved despite the context window size constraint of the machine learning model to ensure an enduring understanding of the chat or conversation history. When the token constraint of the context window size is reached, a summary of the chat history is generated to replace the chat history. The original content of the summarized chat history is stored in a lookup table and indexed by keywords. Instructions are provided to the model that allow the model to ask for the original content of the chat history summary which is obtained from the lookup table and provided to the model.
