AI memory, context window, and RAG: clarifying key distinctions

The terms 'memory,' 'context window,' and 'retrieval-augmented generation' (RAG) are often confused, leading to architectural errors in AI systems. The context window is the temporary, immediate workspace for an AI model, akin to its short-term working memory. RAG is a technique used to fetch relevant information into this context window, typically from external documents or, in the case of AI agents, from their own persistent memory. True memory in AI refers to the long-term, persistent state that outlives individual sessions, encompassing not just retrieval but also storage, consolidation, and forgetting mechanisms. AI
