Introducing the token-efficient memory algorithm. Mem0’s new algorithm hits 91.6 on LoCoMo, 93.4 on LongMemEval, and 64.1/48.6 on BEAM (1M/10M) while averaging < 7,000 tokens per retrieval call, at 3-4x lower token cost. Full-context approaches on these benchmarks run at 25,000+ tokens. What it means for developers: You can now run agent memory that is cost-efficient at production scale without sacrificing quality. What’s changed: - Single-pass ADD-only extraction The previous system used two LLM passes: identify candidates, then reconcile with ADD/UPDATE/DELETE. That reconciliation destroyed context. The new algorithm: one pass, only adds. When information changes, both facts survive. The system reasons about how things evolved, not just where they landed. ~50% faster extraction. - Agent-generated facts are first-class Users and agents both produce facts during a conversation. Now both are stored with equal weight. This change increased the single-session (assistant) score from 46.4 to 100.0 on LongMemEval. - Entity linking Every memory is analyzed for entities, people, places, concepts. These are embedded and stored in a separate lookup layer, linking memories about the same person, place, or concept across sessions and months. - Multi-signal retrieval Retrieval stack now runs three scoring passes in parallel and fuses the results: semantic similarity, keyword matching, and entity matching. The combined score outperforms individual signal scores on every benchmark. - Keyword normalization, Queries like “what meetings did I attend?” now match memories containing “attending a meeting.” Small change, measurable impact. Available today on platform + open-source SDK. Full eval framework open-sourced. Full writeup and benchmarks in thread 🧵👇
