# Language Understanding (Law) on MMLU Professional Law (test) Source: [Language Understanding (Law) on MMLU Professional Law (test)]() Collection index: [llms.txt]() Data updated: 2026-05-15T08:46:59.042Z Evaluation of Language Understanding performance specifically on the test split of the MMLU Professional Law benchmark. 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 | Language Understanding (Law) | | Dataset (including any stated split) | MMLU Professional Law (test) | | Metric | Accuracy | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 7 of 7 | | 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 - [Accuracy](): Higher is better; unit: PERCENT. ## Recorded results | Method | Accuracy | Result date | Report paper | | --- | --- | --- | --- | | GEPA | 80.78 | Not recorded | 6a06a87ddbc836b87d829f8b | | ProTeGi | 80.66 | Not recorded | 6a06a87ddbc836b87d829f8b | | COPRO | 80.43 | Not recorded | 6a06a87ddbc836b87d829f8b | | MIPRO | 79.94 | Not recorded | 6a06a87ddbc836b87d829f8b | | Baseline | 78.89 | Not recorded | 6a06a87ddbc836b87d829f8b | | PSAO\_LLM | 78.45 | Not recorded | 6a06a87ddbc836b87d829f8b | | PromptAgent | 77.84 | Not recorded | 6a06a87ddbc836b87d829f8b | ### GEPA Accuracy: 80.78.
