CueMap

About

CueMap is an open source memory engine designed for AI agents and developed in Rust. It merges precise lexical and structural retrieval with an integrated local MiniLM reranker, eliminating the need for external model queries. With one million memories, typical read operations average 2.63 milliseconds for lexical access and 8.36 milliseconds for hybrid retrieval. Performance metrics show a raw Hit@20 of 96.2% on LongMemEval, 96.1% on LoCoMo, 80.3% on BEAM 1M, and 67.0% on BEAM 10M. The system is accessible via MCP, Python and TypeScript SDKs, Docker, or a command line interface, providing source verified outcomes and fully traceable operations.
