Generate Custom AI Images with OpenAI GPT-Image-1 Model
Last edited 9 days ago
How it works
- Trigger the workflow manually via the n8n UI.
- Define key parameters like the image prompt, number of images, size, quality, and model.
- Send a POST request to OpenAI’s image generation API using those inputs.
- Split the API response to handle multiple images.
- Convert the base64 image data into downloadable binary files.
Set up steps
Initial setup takes around 5–10 minutes. You’ll need an OpenAI API key, a configured HTTP Request node with credentials, and to customize the prompt/parameter fields in the “Set Variables” node. No advanced config or external services needed.
Important Note You have to make sure to complete OpenAI's new verification requirements to use their new image API: https://help.openai.com/en/articles/10910291-api-organization-verification
It only takes a few minutes and does not cost any money.
