Inquiry Topic

I am looking for a way to bypass the image limit mentioned in the documentation (https://learn.microsoft.com/en-us/azure/ai-foundry/openai/quotas-limits?tabs=REST#quotas-and-limits-reference) under the section titled "GPT-4o and GPT-4.1 maximum images per request (number of images in the messages array or conversation history)," as I am running into this restriction.

Details

I am currently inputting 10 images and a PDF into the Azure OpenAI API, all encoded in Base64. Since the PDF has 49 pages, it seems to be hitting the image count limit.

I would like to know how to structure my request to avoid this restriction.

Below is the original text in Japanese.

Hi 85795786

100 pages, 32 MB max file limit is for Text based pdfs.

10 pages is max page limit for image-based pdf. You can put 10 pages in 1 pdf.

Please chunk larger pdfs to smaller pdf if it is crossing the page limit

Please chain the API calls separately to parse the text-based content pdf and image-based content pdfs to avoid page limit.

All generated insights can be appended to a Summary list before generating a final summary.

Product group already acknowledged the gap and working to increase the image limit in pdfs.
