This ComfyUI workflow leverages the OpenAI GPT-Image-1 model to transform input images into new, AI-generated images. By utilizing the OpenAIGPTImage1 node, this workflow connects directly to the OpenAI API, allowing for seamless image-to-image generation. The process begins with the LoadImage node, which imports the initial image that you want to transform. Once the image is loaded, the OpenAIGPTImage1 node processes it using the powerful capabilities of the GPT-Image-1 model. Finally, the SaveImage node captures the output, storing the newly generated image for further use or analysis.
The workflow is particularly useful for creative professionals and developers who need to generate variations of existing images or explore creative concepts through AI. The integration with OpenAI's API ensures high-quality outputs, while the MarkdownNote node provides a convenient way to document the process or add annotations. This workflow is ideal for environments where secure network access is available, as it requires API connectivity through `127.0.0.1` or `localhost`.

Run it from Python or TypeScript with the Comfy SDK. The same code targets Comfy Cloud or a ComfyUI you host yourself — only the base URL changes.
# Install (beta)
pip install comfy-sdk # Python
