Trying myself with GPT 4 Vision (directly using the API), I get response:

"The image shows a total of four coins."

For the exact same image with a prompt "how many coins do I have?"

I keep getting the same thing every time.

If I ask "what is the value shown on the image?"

I get the following:

"The image shows four coins, and from what I can discern, three of the coins have the number "1" on them, which likely indicates that they are one-unit coins in their respective currency. The fourth coin, which is a different color and appears to be bi-metallic, has the number "2" on it, suggesting it is a two-unit coin. The total value shown by the coins, therefore, appears to be 5 units of their currency. However, without knowing the specific currency, I cannot determine the exact monetary value in any other terms."

So to me it's obvious gpt4-vision model can handle this question.

Edit: I also get for regular ChatGPT "You have a total of four coins in the image."

Now I tried to ask GPT4 Vision to find the Dog, and it said:

"The dog is located approximately at 0.29, 0.36, 0.70, 0.90." - Just eyeing it, it may seem decently accurate, but not 100%.

My difference is that I took a screenshot from your pictures rather than providing the original though, so that could also probably affect answers.

Prompt for the dog was: "Find the dog. Return its location in the format x_min, y_min, x_max, y_max. Respond with 0-1 as percentages."
