UnverifiedEven 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% similarUnverifiedCommon solutions for long-conversation memory management include sliding window truncation, summary compression, and vector memory, used to address the problem of messages exceeding the token limit due to a limited context window71% similarUnverifiedA 262K token context means the model can process approximately 200,000 Chinese characters in a single conversation, at the cost of the KV cache occupying large amounts of VRAM and memory as the context grows.71% similar
