Background Mode for image generation - gpt-image-1 model

Is the newly introduced background mode supposed to work for image generation or is it only available for O3 thinking and deep search? I have been trying to use it for image generation but I could not make it work.

It works using the responses API.

I am also using the responses API. I tried both background and streaming together and also just background. I get back a responseId and when I poll, I keep getting “in-progress” forever. Also tried sequence numbers with the streaming, and again no stream events arrive during polling. Am I doing something wrong?

It is normal, gpt-image-1 takes a little longer to complete.

When the status change to complete it will have a complete response.
