Hybrid Memory: Vector + Graph + KV
Hybrid memory runs three stores in parallel — vector for semantic similarity, KV for fast fact lookup, graph for entity-relationship reasoning — with a scoring layer that fuses them on retrieval. This is a widely used production pattern for external memory; Mem0 (Chhikara et al., 2025) is one reference implementation.
Visual edition planned
This lesson isn’t interactive yet.
It is part of the curriculum and will get the same treatment as Phase 1 — a visual cover, hands-on labs, derivations with numeric checks and a quiz. Until then, the original lesson is the best place to read it:
Part of Phase 14 — Agent Engineering. Use the previous / next cards below to keep browsing the phase.
