Annotation Interface AiProvider.ModelConfig

Enclosing class:
AiProvider
@Target(TYPE) @Repeatable(ModelConfigs.class) public static @interface AiProvider.ModelConfig
Annotation used to define a configuration for a specific LangChain4j model class. This configuration is used during code generation for creating service bean providers and configuration blueprints.
Configuration example: 

 langchain4j:
   # provider key
   open-ai:
     # model type
     chat-model:
       # properties introspected from
       api-key: api-key
       model-name: model-name

  • Element Details

    • value

      Class<?> value
      LangChain4j model class to be introspected for code-generated service bean providers.
      Returns:
      LangChain4j model class

    • builder

      Class<?> builder
      Specifies the builder class associated with the LangChain4j model, for configuration introspection.
      Returns:
      the builder class, or Void.class if no builder is specified.
      Default:
      java.lang.Void.class

    • skip

      String[] skip
      Specifies property names or configurations to skip in the configuration blueprint.
      Returns:
      an array of property names or configurations to exclude
      Default:
      {}

    • providerKey

      String providerKey
      Specifies a unique configuration key to identify the service provider for the associated LangChain4j model. If not specified, key is derived from the configuration parent class, example: OpenAiConfiguration.java -> open-ai
      Returns:
      the unique provider key, or an empty string if not specified.
      Default:
      ""

    • weight

      double weight
      Defines the weight of the generated model factory bean. A higher weight indicates higher significance.
      Returns:
      the weight value, default is Weighted.DEFAULT_WEIGHT in no constant of the double type is defined and annotated with AiProvider.DefaultWeight in the same class.
