Mem0 Says Its Algorithm Scores 92.5 on LoCoMo, 94.4 on LongMemEval
Summary
Mem0 says its new memory algorithm, released in April 2026, scores 92.5 on LoCoMo, up from 71.4, and 94.4 on LongMemEval. The algorithm uses single-pass ADD-only extraction, one LLM call with no UPDATE or DELETE. Mem0 notes the scores come from its managed platform, and open-source users should expect similar but not identical gains.
Key Points
- Mem0 reports 64.1 on BEAM at 1M tokens, a production-scale memory evaluation.
- Mem0 says the algorithm reaches 98.2 on assistant memory recall within LongMemEval.
- Mem0 opens its evaluation framework so anyone can reproduce the benchmark numbers.
