OpenAI error code 429 - temporary ban/rate limit

Questions
1

I’ve been using the OpenAI API with great success the last several weeks (text and assistant). However as of yesterday tried out the new image model and immediately faced an error code of 429 from the first attempt.

" You are being rate limited
The owner of this website (api.openai) has banned you temporarily from accessing this website"

I thought maybe it was the use of the model so i tried the same with Dalle 2 & 3 with exactly the same issue. I have since used the text models again with no problem. Whats more interesting is i’ve actually tried both dalle models on MAKE, and they executed just fine - which obviously makes it look like its something to do with my N8N setup - or even N8N itself.

My organisation on OpenAI is verified, the account is appropriately funded, and my usage is no where near the limits.

Has anyone else faced this, or get any ideas? I’ve tried various input types including both RAW & JSON. For both Dalle and the new image-1 model i’ve been using an HTTP request but even with the OpenAI node i still get the same problem when trying to create images.

Any input would be greatly appreciated!

OpenAI has different Rate Limits.
One is “Requests per Minute”.

If many items are processed in a workflow without using a loop and then passed to an OpenAI node, all the requests will be sent to OpenAI at the same time. This can quickly cause you to reach your requests per minute limit.

For further assistance, please share your workflow or the specific part that is causing issues. Otherwise, we can only guess what the problem might be.
