Class InferenceConfiguration

java.lang.Object
software.amazon.awssdk.services.bedrockruntime.model.InferenceConfiguration
All Implemented Interfaces:
Serializable, SdkPojo, ToCopyableBuilder<InferenceConfiguration.Builder,InferenceConfiguration>
@Generated("software.amazon.awssdk:codegen") public final class InferenceConfiguration extends Object implements SdkPojo, Serializable, ToCopyableBuilder<InferenceConfiguration.Builder,InferenceConfiguration>

Base inference parameters to pass to a model in a call to Converse or ConverseStream. For more information, see Inference parameters for foundation models.

If you need to pass additional parameters that the model supports, use the additionalModelRequestFields request field in the call to Converse or ConverseStream. For more information, see Model parameters.

  • Method Details

    • maxTokens

      public final Integer maxTokens()

      The maximum number of tokens to allow in the generated response. The default value is the maximum allowed value for the model that you are using. For more information, see Inference parameters for foundation models.

      Returns:
      The maximum number of tokens to allow in the generated response. The default value is the maximum allowed value for the model that you are using. For more information, see Inference parameters for foundation models.

    • temperature

      public final Float temperature()

      The likelihood of the model selecting higher-probability options while generating a response. A lower value makes the model more likely to choose higher-probability options, while a higher value makes the model more likely to choose lower-probability options.

      The default value is the default value for the model that you are using. For more information, see Inference parameters for foundation models.

      Returns:
      The likelihood of the model selecting higher-probability options while generating a response. A lower value makes the model more likely to choose higher-probability options, while a higher value makes the model more likely to choose lower-probability options.

      The default value is the default value for the model that you are using. For more information, see Inference parameters for foundation models.

    • topP

      public final Float topP()

      The percentage of most-likely candidates that the model considers for the next token. For example, if you choose a value of 0.8 for topP, the model selects from the top 80% of the probability distribution of tokens that could be next in the sequence.

      The default value is the default value for the model that you are using. For more information, see Inference parameters for foundation models.

      Returns:
      The percentage of most-likely candidates that the model considers for the next token. For example, if you choose a value of 0.8 for topP, the model selects from the top 80% of the probability distribution of tokens that could be next in the sequence.

      The default value is the default value for the model that you are using. For more information, see Inference parameters for foundation models.

    • hasStopSequences

      public final boolean hasStopSequences()
      For responses, this returns true if the service returned a value for the StopSequences property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • stopSequences

      public final List<String> stopSequences()

      A list of stop sequences. A stop sequence is a sequence of characters that causes the model to stop generating the response.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasStopSequences() method.

      Returns:
      A list of stop sequences. A stop sequence is a sequence of characters that causes the model to stop generating the response.

    • toBuilder

      public InferenceConfiguration.Builder toBuilder()
      Description copied from interface: ToCopyableBuilder
      Take this object and create a builder that contains all of the current property values of this object.
      Specified by:
      toBuilder in interface ToCopyableBuilder<InferenceConfiguration.Builder,InferenceConfiguration>
      Returns:
      a builder for type T

    • builder

      public static InferenceConfiguration.Builder builder()

    • serializableBuilderClass

      public static Class<? extends InferenceConfiguration.Builder> serializableBuilderClass()

    • hashCode

      public final int hashCode()
      Overrides:
      hashCode in class Object

    • equals

      public final boolean equals(Object obj)
      Overrides:
      equals in class Object

    • equalsBySdkFields

      public final boolean equalsBySdkFields(Object obj)
      Description copied from interface: SdkPojo
      Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

      If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

      Specified by:
      equalsBySdkFields in interface SdkPojo
      Parameters:
      obj - the object to be compared with
      Returns:
      true if the other object equals to this object by sdk fields, false otherwise.

    • toString

      public final String toString()
      Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
      Overrides:
      toString in class Object

    • getValueForField

      public final <T> Optional<T> getValueForField(String fieldName, Class<T> clazz)

    • sdkFields

      public final List<SdkField<?>> sdkFields()
      Specified by:
      sdkFields in interface SdkPojo
      Returns:
      List of SdkField in this POJO. May be empty list but should never be null.
