UnverifiedThe context window is the upper limit of text a large language model can see at one time, usually measured in tokens, and anything beyond it is truncated or discarded.79% similarUnverifiedSummarization middleware is commonly used to compress long conversation histories or large documents in order to fit content within a model's limited context window.77% similarUnverifiedContext is the upper limit of information the model can "see" in each response, measured in tokens, with roughly one Chinese character corresponding to one to two tokens; when the conversation grows longer or files grow larger, earlier information is pushed out of the window, causing the model to forget.77% similarUnverifiedThe technical basis of long-document processing capability is the context window size; the larger the context window, the more content the model can remember in a single conversation; but even if the window is large enough, the model's recall of information in the middle of long text may still be weaker than for the beginning and the end.74% similarUnverifiedThe full chat history displayed in a chat application's interface is not necessarily consistent with the input the model actually receives at that moment; the application may summarize earlier conversation, omit content, or retrieve historical information on demand.74% similar
