# samplingStrategy

The strategy for selecting existing samples as examples in the prompt.

## Declaration

```swift
var samplingStrategy: SampleGenerator<SampleType>.SamplingStrategy?
```

## Discussion

Discussion When nil, the generator shows no examples and doesn’t retry on repetition. When set, the strategy also controls retry behavior when the model repeats itself.
