GenerationOptionsRepresentable

public protocol GenerationOptionsRepresentable : Sendable

A type that represents options for controlling model response generation.

For Gemini models, this may be a GenerationConfig value. For the SystemLanguageModel provided by the Apple Foundation Models framework, this may be a GenerationOptions or a Foundation Models GenerationOptions value. For hybrid (on-device and cloud) configurations, use hybrid(gemini:foundationModels:)-(_,FirebaseAI.GenerationOptions) to specify options for each model.
