Wrong "The image data you provided does not represent a valid image" Error when sending only JPG image links

API Bugs

I’m seeing an occasional error from the chatGPT API returning that “The image data you provided does not represent a valid image. Please check your input and try again with one of the supported image formats: [‘image/jpeg’, ‘image/png’, ‘image/gif’, ‘image/webp’].” However I’m only sending image links to jpeg files. The images are small in size mostly below 100KB and we only send up to 5 images total in the request. This error message seems to be incorrect.

Something I did notice is we only seem to get this error when sending multiple image links, where at least 2 of them are duplicates (same link exists in 2 different image_input objects). See example request below(links 1 & 3 are the same). Is this expected behavior or is this a bug?

Think it’s a bug. I’ve also had the same error accessing o4-mini via a unified API and submitting only one image. Waited a few minutes and it worked.

Had this issue persisting again for longer. FYI, got it working by reformatting the image using Pillow in Python:

from PIL import Image
img = Image.open(“old.jpg”).convert(“RGB”)
img.save(“new.jpg”, “JPEG”, quality=95)
