LLM calls.
Ever.

Every other memory product pipes your data through a language model and bills you for it — on write, and again on read. LongMemory is pure math. Nothing to prompt. Nothing to leak.

03Accuracy, without the LLM

79% judged
on LoCoMo.

Raw transcripts in, zero extraction — then Claude Sonnet 5 graded whether the retrieved context answered the question. Same LLM-as-judge method the systems below report, run against memory that never called a model. We publish the script; run it yourself.

* Self-reported across the full benchmark in the mem0 paper (arXiv:2504.19413), each using its own judge. Ours is LoCoMo story 1 (149 questions) graded by Claude Sonnet 5; zero-LLM retrieval alone scores 71% recall@10 across all 1,531.
