Agent Memory Becomes Its Own Product Category

Four new frameworks in one day — each with 6K-12K stars — signal that agent memory has graduated from "feature" to "product category":

• memU (12.3K stars) — Memory for always-on proactive agents with filesystem-like hierarchy and proactive intent prediction. PostgreSQL + pgvector backend. GitHub
• Memori (12.3K stars) — SQL-native memory layer with three hierarchical levels (Entity/Process/Session). Zero-config, framework-agnostic, zero-latency background augmentation. GitHub
• MemOS (6.1K stars) — Memory Operating System with graph-structured inspectable memory (Neo4j + Qdrant). 72% lower token usage claim. "Skill memory" for cross-task reuse. GitHub
• Zep Graphiti — Temporal knowledge graphs outperforming MemGPT on Deep Memory Retrieval (94.8% vs 93.4%), 90% latency reduction. Accepts JSON business data, not just chat. arXiv
