UnverifiedThe three most common strategies for persisting conversation history are Window Buffer Memory, Summary Memory, and Vector Store Memory.69% similarUnverifiedTwo default practices for long-term memory: extraction should be placed asynchronously outside the reply path (because the facts of this conversation are already in this session's history); take a snapshot of memory at the start of each conversation (the memory block is placed before the history, and updating it midway would break the cache).67% similarUnverifiedCommon strategies for handling extremely long conversation history include a sliding window that retains the most recent several turns, generating summaries of earlier history and putting them back into the context, and scoring information to keep only the important parts.67% similarUnverifiedIn Agent systems, long-term memory is typically implemented by storing historical conversations or external knowledge into a vector database and retrieving relevant snippets to inject into the context when needed — this is the foundational logic of RAG (Retrieval-Augmented Generation) technology.67% similarUnverifiedConversational recall benchmarks such as LoCoMo and LongMemEval measure question-answering ability over conversation history, rather than whether memory has changed the actual behavior of tool-using agents.66% similar
