Cost calculation of sending an image to gpt-4o model

API
1

I have been sending an image to gpt api with gpt-4o as model by enoding the image as base64.

Normally I calculate the cost for a single api call based on the input and output tokens in response[‘usage’].

What about in case of sending image as base64 encoding? will the above cost calculation method still the same or any changes that are need to be done.

path = f'imu/{ticker}'
        base64_image = self.encode_image(f"{path}/page_{content_page}.jpg")
        image_url = f"data:image/jpeg;base64,{base64_image}"
        images_info = []
        images_info.append(
            {
            "type": "text",
            "text": "This is the image that should be taken as context to give the output",
            }
        )
        image_dict = {
            'type': "image_url",
            "image_url": {
                "url": image_url
            },
        }
        images_info.append(image_dict)
        messages.append(
            {
                "role": "user",
                "content": images_info
            }
        )
        prompt = ANNUAL_REPORT_SPLITTER_PROMPT3
        data, messages = self.get_gpt_response(prompt, messages, model="gpt-4o")
