AgentKeeper – cognitive persistence layer for AI agents
Cross-provider agent memory is clever, but LLM context windows keep growing and RAG is already standard.

DeltaMemory – Persistent cognitive memory for production AI agents

AI Analysis
●MidSolve My Problem
Knowledge graph compression (3,714x token ratio) is impressive, but 'persistent agent memory' is crowded territory.
Strengths
- •Token compression ratio (26M → 7K tokens) with 97% cost reduction is concrete and measurable—knowledge graph extraction is real infra work
- •89% LoCoMo benchmark result shows rigor—SOC 2/HIPAA readiness + VPC deployment matters for enterprise
- •Framework integrations (LangChain, CrewAI, n8n) show pragmatic design—50ms p50 latency is production-grade
Weaknesses
- •Managed SaaS + early access only—no open-source reference, no self-hosted story, hard to evaluate claims independently
- •Persistent agent memory is solved by vector DBs (Pinecone, Weaviate) + RAG frameworks—the 'fact extraction' angle is incremental, not novel

Post Description
Most AI agents forget everything between sessions. We built DeltaMemory to fix that.
It's a cognitive memory layer that gives agents persistent recall, automatic fact extraction, and temporal reasoning — via a single SDK call.
Key numbers: - 89% accuracy on LoCoMo long-term conversation benchmark - 50ms p50 retrieval latency - 97% cost reduction vs raw token re-processing
Open source SDKs, works with any LLM stack. Currently in early access.
Happy to answer questions about the architecture, benchmark methodology, or how we handle knowledge graphs.
