# Long-context Question Answering on LoCoMo Temporal 2024 Source: [Long-context Question Answering on LoCoMo Temporal 2024]() Collection index: [llms.txt]() Data updated: 2026-04-23T09:19:20.348Z Evaluation of Long-context Question Answering performance on the LoCoMo Temporal 2024 dataset, measured using F1 score, BLEU-1, and LLM-as-a-Judge metrics. 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-context Question Answering | | Dataset (including any stated split) | LoCoMo Temporal 2024 | | Metric | F1 Score | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 12 of 12 | | 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 - [F1 Score](): Higher is better; unit: PERCENT. - [BLEU-1](): Higher is better; unit: PERCENT. - [LLM-as-a-Judge Score](): Higher is better; unit: PERCENT. ## Recorded results | Method | F1 Score | Result date | Report paper | | --- | --- | --- | --- | | Lyzr Cognis | 62.68 | Not recorded | 69e9a76255a3c32af89f6ea4 | | Mem0g | 51.55 | Not recorded | 69e9a76255a3c32af89f6ea4 | | Mem0 | 48.93 | Not recorded | 69e9a76255a3c32af89f6ea4 | | A-Mem | 45.85 | Not recorded | 69e9a76255a3c32af89f6ea4 | | Zep | 42 | Not recorded | 69e9a76255a3c32af89f6ea4 | | A-Mem\* | 35.4 | Not recorded | 69e9a76255a3c32af89f6ea4 | | LangMem | 30.75 | Not recorded | 69e9a76255a3c32af89f6ea4 | | MemGPT | 25.52 | Not recorded | 69e9a76255a3c32af89f6ea4 | | LoCoMo | 18.41 | Not recorded | 69e9a76255a3c32af89f6ea4 | | OpenAI | 14.04 | Not recorded | 69e9a76255a3c32af89f6ea4 | | ReadAgent | 12.6 | Not recorded | 69e9a76255a3c32af89f6ea4 | | MemoryBank | 9.68 | Not recorded | 69e9a76255a3c32af89f6ea4 | ### Lyzr Cognis F1 Score: 62.68.
