# Open-ended tasks on MT-Bench (test) Source: [Open-ended tasks on MT-Bench (test)]() Collection index: [llms.txt]() Data updated: 2026-05-12T13:14:56.599Z Evaluation of model performance on the test split of MT-Bench specifically for open-ended tasks, reporting Win Rate and associated Cost. 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 | Open-ended tasks | | Dataset (including any stated split) | MT-Bench (test) | | Metric | Win Rate | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 2 of 2 | | 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 - [Win Rate](): Higher is better; unit: PERCENT. - [Cost](): Lower is better; unit: SCALAR. ## Recorded results | Method | Win Rate | Result date | Report paper | | --- | --- | --- | --- | | COPE | 44.8 | Not recorded | 68fa7ba31e209131cea89850 | | Large | 42.5 | Not recorded | 68fa7ba31e209131cea89850 | ### COPE Win Rate: 44.8. Result ID: 6a0327ce47f34ce924e7937e. [Reporting paper]() [Method origin paper]() Recorded evaluation configuration: {"Small Model":"EXAONE-3.5-2.4B-Instruct","Large Model":"GPT-4o-mini","Judge Model":"GPT-4o"}. This record does not assert independent reproduction. ### Large Win Rate: 42.5. Result ID: 6a0327ce47f34ce924e7937d. [Reporting paper]() Recorded evaluation configuration: {"Model":"GPT-4o-mini"}. This record does not assert independent reproduction. Page 1 of 1. This is an index page, not the full collection.
