It looks like the vision costs the same for GPT-4o vs mini.
Both start with 150x150px and if you click the (i) it says mini uses way more base tokens and way more tile tokens, it still costs the same...

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"
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.
Since the base token counts increase proportionally (which makes even less sense) I have a hunch there's a JavaScript bug instead.
