ComfyUI Custom Nodes for Google Vertex AI

This repository contains ComfyUI custom nodes that allow you to leverage the power of Google's Vertex AI models, specifically Veo3 for video generation and Imagen4 for image generation, directly within your ComfyUI workflows.

Features

• Veo3 Node: Generate high-quality videos from text prompts using Google's state-of-the-art Veo3 model.
• Imagen4 Node: Create stunning images from text prompts with Google's powerful Imagen4 model.
