VerifiedAn agent's memory includes short-term memory (conversational context window, typically 4K–128K tokens), long-term memory (vector database), and procedural memory (intermediate state cache for tool calls).82% similarUnverifiedWhen processing a long document of 8000 tokens, the KV cache may consume several additional GB of memory.79% similarUnverifiedEven if the context window expands to millions of tokens, cross-session memory remains an engineering challenge, usually requiring an external vector database or a structured memory layer to achieve.77% similarUnverifiedThe conversational memory mechanism is essentially concatenating historical messages into the context window, so context length limits (e.g., 4K, 8K, 128K tokens) become a key constraint.76% similarUnverifiedMemGAS在LongMemEval-S上构建记忆处理约52.9M input tokens，Summary和Keyword带来的额外内存约27MB，约为原始记忆的10%76% similar
