DeltaMemory: A Persistent Memory Layer for AI Agents That Learns Over Time
By
Shreejit Sen
Hard to chew. Probably not worth the jaw work.
Summary
DeltaMemory is a new AI memory layer designed to solve the problem of AI agents forgetting information between sessions. Unlike vector databases or RAG systems, it extracts facts, builds knowledge graphs, and learns over time. The product is built in Rust, claims to be #1 on LoCoMo, 2x faster than alternatives like Mem0, and 97% cheaper at scale.
