 _Repetitions_ run an experiment multiple times to account for LLM output variability. Since LLM outputs are non-deterministic, multiple repetitions provide a more accurate performance estimate.
 
-Configure repetitions by passing the `num_repetitions` argument to `evaluate` / `aevaluate` ([Python](https://docs.smith.langchain.com/reference/python/evaluation/langsmith.evaluation._runner.evaluate), [TypeScript](https://docs.smith.langchain.com/reference/js/interfaces/evaluation.EvaluateOptions#numrepetitions)).
