State/ history RAG Memory Prompt engineering Structured outputs User preferences

strategies Periodically condense old turns into brief summaries ✅Retains longer-range knowledge within context limits 👎Relies on summary quality – additional compute Sequential (naive) From simple to smart Keep only the last N messages; drop the rest ✅Constant cost & latency 👎Forgets earlier details Feed entire chat history to the model every turn ✅Zero engineering effort 👎Context explosions → slow/expensive Sliding Window Summarization Extract & index memories. Fetch relevant pieces when possible. ✅Scales to unlimited history; adaptive recall 👎Relies on extraction quality Retrieval-based -

Memory Server RESTful API server for managing short term and long term memory automatically Short-term memory • Automatic summarization • Configurable window sizes for recent messages Long-term memory • Search for relevant memories • Extract topic & named entity recognition • Namespace support for proper isolation Agent Memory Server User input AI app Short-term memory management Long-term memory management LLMs https://github.com/redis-developer/agent-memory-server -

& Decay Strategies • Recency scoring: [ranking] ◦ Soft decay: freshness & novelty • Forgetting: [hard delete] ◦ age based ◦ Inactivity ◦ Budget • Summarization [Condensation] -

Memory Server feature comparison Redis Agent Memory Server Google Vertex MemoryBank AWS AgentCore Memory Auto-generate memories Yes, with choice of LLM and support for scopes, topics Yes, uses Gemini Yes, uses Bedrock models- Claude, Llama etc. Advanced retrieval Yes, Combine similarity, with recency, freshness, metadata etc. Limited, Similarity Search only (reference) Limited, Similarity Search only (reference) Decay and Freshness Yes, Configuring “forgetting” rules based on age, recency, budget etc. at namespace/userid level. Limited, TTL only Limited, TTL only Working memory mgmt Yes, incl. automatic expiration, tiering to/from long-term memory, No. Requires separate “Session” store and triggering generation Yes, includes automatic short-term (session-scoped) and long-term memory Cloud choice Yes, Redis available on all 3 clouds and on-prem. Memory Server is Open source today (w/ service coming) No, GCP only No, AWS only
