GPT-Image + n8n

Questions
1

Hello everyone,

Every day I have dozens of image prompts to send to gpt.

But I’m tired of waiting for one image to be created only to have to recreate another.

Is it possible to automate this with n8n? Is it chargeable with the gpt API?

Thanks

Absolutely you can actually automate bulk image generation in n8n. You can follow this guide.

  • n8n for workflow automation
  • Gemini API for prompt optimization and variation
  • Nano Banana for fast and cost-effective image generation

This stack works well because:

  • Gemini enhances and varies prompts automatically
  • Nano Banana is cheaper and faster than OpenAI DALL-E, making it ideal for bulk operations
  • n8n handles batch processing for multiple images efficiently

By using this setup, you can save hours daily and potentially see a return on investment within the first week.
