Why is my GPT-4 Vision Preview API call hitting token rate limits with a 600x300 .jpg?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

Hi - I’m getting an error when sending a 600x300 .jpg image along with a short prompt. The response is as follows:

Rate limit reached for gpt-4-vision-preview in organization org-[MY-ORGANIZATION] on tokens per min. Limit: 10000 / min. Please try again in 6ms. Visit OpenAI Platform to learn more.

I’ve also tried using the API from my personal account with the same result. Here’s the code I’m using to call the API:

PYTHON
def get_image_analysis(api_key, prompt_text, image_path=None):  
    client = OpenAI(api_key=api_key)  
    headers = {  
        "Content-Type": "application/json",  
        "Authorization": f"Bearer {api_key}"  
    }  
    image_data = encode_image_to_base64(image_path)

    payload = {
        "model": "gpt-4-vision-preview",
        "messages": [
            {
                "role": "user",
                "content": prompt_text 
            },
            {
                "role": "user",
                "content": f"data:image/jpeg;base64,{image_data}"
            }
        ],
        "max_tokens": 300
    }
    response = requests.post("https://api.openai.com/v1/chat/completions", headers=headers, json=payload)
    return response.json()

Any ideas on why this rate limit error might be occurring?

The error message indicates that the API thinks you’re sending too many tokens in a given minute for the model you're using. This “tokens per minute” limit counts all tokens in your API call—including those generated from converting your image to a base64 string.

There are two potential issues to check:

  1. Size of the Base64 Image Data
    When you encode an image as a base64 string, the resulting text can be very large. Even if your image is 600×300 pixels, the file size (especially after base64 conversion) could be significant. Since every character in that string is tokenized, you might inadvertently be sending thousands of tokens, causing you to exceed the 10,000 tokens per minute limit.

  2. Repeated API Calls or Unexpected Looping
    Even if a single call is within limits, if your application is sending many requests (or if there’s an unintended loop), you might hit the limit. Also, note that switching between different accounts or keys may not bypass the limit if the requests are still attributed to the same organization.

Recommendations

  • Reduce Image Size or Quality:
    Consider further compressing or resizing your image if possible. Smaller images produce shorter base64 strings, lowering the token count.

  • Avoid Embedding the Entire Base64 String as a Message:
    If the API supports it in a different way, try sending the image as a file or binary upload rather than embedding it directly into a message. This avoids having the image content counted as tokens.

  • Monitor Your Request Frequency:
    Ensure your application isn’t sending requests in quick succession that cumulatively exceed the token rate limit.

  • Check the Documentation:
    Since you’re using a preview API endpoint (gpt-4-vision-preview), review any specific guidelines. There might be recommendations on the maximum image size or best practices for including image data.

By addressing these points, you should be able to reduce the token usage per minute and avoid the rate limit error.
