constructor

new GeminiImageGenerationCapabilityImpl(
provider: BaseProvider,
client: GoogleGenAI,
): GeminiImageGenerationCapabilityImpl
Creates a new Gemini image generation capability.
Parameters
- provider: BaseProvider
  Parent provider instance
- client: GoogleGenAI
  Initialized Gemini / Imagen SDK client
Returns GeminiImageGenerationCapabilityImpl
- Defined in src/providers/gemini/capabilities/GeminiImageGenerationCapabilityImpl.ts:63

Methods

generateImage

generateImage(
    request: AIRequest<ClientImageGenerationRequest>,
    _executionContext?: MultiModalExecutionContext,
    signal?: AbortSignal,
): Promise<AIResponse<NormalizedImage[]>>
Generates images using Gemini / Imagen 4 API.

Responsibilities:
- Resolves reference images to bytes
- Adjusts prompt for reference IDs
- Calls Imagen 4 generateImages endpoint
- Normalizes output into NormalizedImage[]
Parameters
- request: AIRequest<ClientImageGenerationRequest>
  Unified client image generation request
- Optional_executionContext: MultiModalExecutionContext
  Optional execution context
- Optionalsignal: AbortSignal
  AbortSignal for request cancellation
Returns Promise<AIResponse<NormalizedImage[]>>

generateImageStream

generateImageStream(
    request: AIRequest<ClientImageGenerationRequest>,
    _executionContext?: MultiModalExecutionContext,
    signal?: AbortSignal,
): AsyncGenerator<AIResponseChunk<NormalizedImage[]>>
Streaming image generation for Gemini / Imagen 4.

Emits exactly one chunk when the images are ready, similar to OpenAI streaming.
Parameters
- request: AIRequest<ClientImageGenerationRequest>
- Optional_executionContext: MultiModalExecutionContext
- Optionalsignal: AbortSignal
Returns AsyncGenerator<AIResponseChunk<NormalizedImage[]>>
