## New Memory Algorithm (April 2026)

| Benchmark | Old | New  | Tokens  | Latency p50  |
| --- | --- | --- | --- | --- |
| **LoCoMo** | 71.4 | **91.6** | 7.0K  | 0.88s  |
| **LongMemEval** | 67.8 | **94.8** | 6.8K  | 1.09s  |
| **BEAM (1M)** | — | **64.1** | 6.7K  | 1.00s  |
| **BEAM (10M)** | — | **48.6** | 6.9K  | 1.05s  |

All benchmarks run on the same production-representative model stack. Single-pass retrieval (one call, no agentic loops).

**What changed:**
- **Single-pass ADD-only extraction** -- one LLM call, no UPDATE/DELETE. Memories accumulate; nothing is overwritten.
- **Agent-generated facts are first-class** -- when an agent confirms an action, that information is now stored with equal weight.
- **Entity linking** -- entities are extracted, embedded, and linked across memories for retrieval boosting.
- **Multi-signal retrieval** -- semantic, BM25 keyword, and entity matching scored in parallel and fused.
- **Temporal Reasoning** -- time-aware retrieval that ranks the right dated instance for queries about current state, past events, and upcoming plans.

See the [migration guide](https://docs.mem0.ai/migration/oss-v2-to-v3) for upgrade instructions. The [evaluation framework](https://github.com/mem0ai/memory-benchmarks) is open-sourced so anyone can reproduce the numbers.

## Research Highlights
- **91.6 on LoCoMo** -- +20 points over the previous algorithm
- **94.8 on LongMemEval** -- +27 points, with +53.6 on assistant memory recall
- **64.1 on BEAM (1M)** -- production-scale memory evaluation at 1M tokens
