How to Build an AI Assistant with Real Long-Term Memory (MemGPT / Letta Pattern)
Mega-context windows fail to resolve context decay and balloon token expenditures. Implementing computer OS memory hierarchies (Working RAM, Swap, and Archival Disks) guarantees sustained continuity across years of user interaction.
AM LABTiered Memory Topologies: Working, Episodic, Archival
Segregate active user personas, episodic conversation chronologies, and cold dense vector embeddings cleanly.
Autonomous Memory Self-Mutation via Function Calling
Empower language models to explicitly invoke memory mutation APIs upon discovering novel factual invariants.
Background Context Compaction and Eviction
Run asynchronous memory pruning agents to compress conversational history into consolidated episodic digests.
