 ** modelId **   <a name="bedrockagentcorecontrol-Type-OpenResponsesEvaluatorModelConfig-modelId"></a>
 The identifier of the model to use for evaluation.   
Type: String  
Required: Yes

 ** maxOutputTokens **   <a name="bedrockagentcorecontrol-Type-OpenResponsesEvaluatorModelConfig-maxOutputTokens"></a>
 The maximum number of tokens to generate in the model response, including visible output and reasoning tokens.   
Type: Integer  
Valid Range: Minimum value of 1.  
Required: No

 ** reasoning **   <a name="bedrockagentcorecontrol-Type-OpenResponsesEvaluatorModelConfig-reasoning"></a>
 The reasoning configuration for reasoning models. Non-reasoning models ignore this configuration.   
Type: [ReasoningConfiguration](API_ReasoningConfiguration.md) object  
Required: No

 ** temperature **   <a name="bedrockagentcorecontrol-Type-OpenResponsesEvaluatorModelConfig-temperature"></a>
 The temperature value that controls randomness in the model's responses. Lower values produce more deterministic outputs.   
Type: Float  
Valid Range: Minimum value of 0. Maximum value of 2.  
Required: No

 ** topP **   <a name="bedrockagentcorecontrol-Type-OpenResponsesEvaluatorModelConfig-topP"></a>
 The top-p sampling parameter that controls the diversity of the model's responses by limiting the cumulative probability of token choices.   
Type: Float  
Valid Range: Minimum value of 0. Maximum value of 1.  
Required: No
