It would help if there was a node for:
Extending the OpenAI Image node to fully support the new gpt-image-1 model parameters.
My use case:
I’m using the OpenAI Image node in n8n to generate icons with the gpt-image-1 model. While the node already supports selecting this model, several gpt-image-1–specific options are missing in the UI. This makes it impossible to generate transparent-background icons or fine-tune outputs with compression/format.
Missing parameters:
-
background(auto, transparent, opaque) -
moderation(auto, low) -
output_format(png, jpeg, webp) -
output_compression(0–100) -
partial_images(0–3) -
stream(boolean)
Parameters like quality, size, and response_format already work correctly with conditional visibility, so this request is focused only on adding the above missing options.
With these added, n8n users could make full use of gpt-image-1, especially for workflows needing transparent icons, custom formats, or optimized outputs.
Any resources to support this?

Are you willing to work on this?
Yes, happy to help test and provide feedback, but would need support from the n8n team or contributors for the TypeScript implementation.
