Standard prefix caching keeps historical visual tokens in a persistent KV cache whose capacity grows linearly with the number of interaction rounds, quickly exhausting the limited memory budget.

UnverifiedTraditional KV cache implementations pre-allocate contiguous GPU memory blocks of maximum length, resulting in an average of 60%–80% of pre-allocated memory being wasted.76% similarVerifiedThe cost of persistent KV caching is a significant increase in storage space, along with the engineering challenge of efficiently locating and loading relevant segments from a massive cache.76% similarUnverifiedThe value of a persistent memory system lies in storing important information externally (such as in a vector store or graph database) and re-injecting only the most relevant fragments into the context window when needed, thereby breaking through the window capacity limit and retaining information across sessions.75% similarUnverifiedMemory is a hard constraint on undo implementation in bitmap editors; actual implementations require a capacity-limited structure that clears older minor operations when memory is tight in order to retain recent ones.74% similarUnverifiedLong-term memory and KV cache solve problems at different levels: KV cache is a short-term computational optimization during inference, and the cache becomes invalid once the conversation is reset; long-term memory, by contrast, must decide which information is worth writing to persistent storage, in what structure to organize it, and how to retrieve it and inject it into context in subsequent conversations.74% similar
