# AWS::Personalize::Solution AutoMLConfig
<a name="aws-properties-personalize-solution-automlconfig"></a>

When the solution performs AutoML (`performAutoML` is true in [CreateSolution](https://docs.aws.amazon.com/personalize/latest/dg/API_CreateSolution.html)), Amazon Personalize determines which recipe, from the specified list, optimizes the given metric. Amazon Personalize then uses that recipe for the solution.
