It almost sounds shady... "it's 30x cheaper per token but you now need 30x more tokens per image"?

Has anyone already validated this based on billed cost? running a batch myself to check

EDIT:

Ok so I captioned 500 images in "low resolution" mode with GPT-4o-mini

Each one took approximately: "completion_tokens=84, prompt_tokens=2989, total_tokens=3073"

Reported GPT-4o-mini cost is $0.25

Using GPT-4o this would cost me $1.33 (also in "low resolution" mode), with this breakdown:

"completion_tokens=98, prompt_tokens=239, total_tokens=337"

Ok I now understand better what happened:

The price for using images as part of your prompt has indeed not changed between GPT-4o-mini and GPT-4o

Yet overall, captioning 500 images now costs me 5x less. This is because when I'm captioning an image, I'm providing both an image and a text prompt. The cost of using the image in the prompt stays the same, but the cost of the text dramatically dropped.
