Show HN: DeltaMemory – Persistent cognitive memory for production AI agents
bikidev Thursday, February 26, 2026Most 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.
