    Gemini 3 custom nodes

    Two lightweight ComfyUI nodes for Gemini 3 preview models:

    • Gemini 3 Pro (Text) – calls gemini-3-pro-preview, accepts optional images and media resolution.
    • Gemini 3 Pro Image – calls gemini-3-pro-image-preview, lets you pick aspect ratio and resolution.

    Usage notes:

    • Supply an API key in the node or set GEMINI_API_KEY in the environment.
    • Image tensors are auto-converted to PNG for requests and returned as standard ComfyUI IMAGE.
    • Image node returns both the generated image and any model text output (captions or system notes).
