# Long Multi-session Question Answering on LoCoMo 1.0 (test) Source: [Long Multi-session Question Answering on LoCoMo 1.0 (test)]() Collection index: [llms.txt]() Data updated: 2026-06-11T10:26:30.377Z Evaluation of Long Multi-session Question Answering performance on the LoCoMo 1.0 test set, reporting F1 scores broken down by Single-hop, Temporal, Adversarial, and Overall categories. A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage. | Scope | Recorded value | | --- | --- | | Task | Long Multi-session Question Answering | | Dataset (including any stated split) | LoCoMo 1.0 (test) | | Metric | Single-hop F1 | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 10 of 10 | | Coverage | All results currently returned for this benchmark | Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol. ## Metrics - [Single-hop F1](): Higher is better; unit: PERCENT. - [Temporal F1](): Higher is better; unit: PERCENT. - [Adversarial F1](): Higher is better; unit: PERCENT. - [Overall F1](): Higher is better; unit: PERCENT. ## Recorded results | Method | Single-hop F1 | Result date | Report paper | | --- | --- | --- | --- | | No limit | 37.5 | Not recorded | 6a2a4136d33dfb23e783943b | | HORMA | 32.3 | Not recorded | 6a2a4136d33dfb23e783943b | | Embedding Retrieval | 26.5 | Not recorded | 6a2a4136d33dfb23e783943b | | Mem0 | 25.6 | Not recorded | 6a2a4136d33dfb23e783943b | | Acon | 23.2 | Not recorded | 6a2a4136d33dfb23e783943b | | A-MEM | 23 | Not recorded | 6a2a4136d33dfb23e783943b | | Truncation | 20.5 | Not recorded | 6a2a4136d33dfb23e783943b | | Embedding | 20.2 | Not recorded | 6a2a4136d33dfb23e783943b | | Slide Window | 15.5 | Not recorded | 6a2a4136d33dfb23e783943b | | ReSum | 11.7 | Not recorded | 6a2a4136d33dfb23e783943b | ### No limit Single-hop F1: 37.5.
