Image Generation - gemini-nano-banana/gemini-nano-banana

Skill: gemini-nano-banana

generate_image_gemini

Description: Generates an image using the Gemini Image API. Supported Models (aliases are internal): The model parameter allows selection between available image generation models. - “gemini-2.5-flash-image” (recommended default for stable, fast response). - “gemini-3-pro-image-preview”. - “gemini-3-flash”

        Aliases for these models are 'nano-banana 2.5' and 'nano-banana 3 Pro' respectively.
        Please use 'gemini-2.5-flash-image' unless the user specifically requests the Gemini 3 model.

    Args:
        model: The image generation model to use (see supported models above). Defaults to "gemini-2.5-flash-image". Supports: 'gemini-3-flash', 'gemini-3-pro-image-preview', 'gemini-2.5-flash-image'
        prompt: A detailed text description for the image to be generated.
        image_name: The filename for the output image, can be a relative path. Defaults to "gemini_output_images.png".
        output_folder: The optional folder path where the image will be saved (use the user's personal directory). If None, uses a server default.
        aspect_ratio: The aspect ratio of the generated image (e.g., '16:9', '1:1', '4:3'). Defaults to '16:9'.
        image_size: The size/resolution of the generated image (e.g., '1K', '2K', '4K'). Defaults to '1K'.

    Return:
        Dict: Result dictionary containing image path, message, and success status.
        output_result["image_path"]: str
        output_result["image_url"]: str
        output_result["message"]: str
        output_result["success"]: bool

Parameters

  • model: string (default: gemini-2.5-flash-image)

  • prompt: string (default: A detailed, cinematic image of a futuristic city.)

  • image_name: string (default: gemini_output_images.png)

  • output_folder: string/null
