Here's a basic example of how to use the GPT-4 Vision API:

import base64
import requests

# Replace with your API key
api_key = "your_api_key_here"

# Image file to analyze
image_path = "path_to_your_image.jpg"

# Read the image file
with open(image_path, "rb") as image_file:
    image_[data](/posts/best-ai-tools-for-data-analysis-2026) = base64.b64encode(image_file.read()).decode("utf-8")

# API endpoint and headers
endpoint = "https://api.openai.com/v1/chat/completions"
headers = {
    "Authorization": f"Bearer {api_key}",
    "Content-Type": "application/json"
}

# API request payload
payload = {
    "model": "gpt-4-vision-preview",
    "messages": [
        {
            "role": "user",
            "content": [
                {
                    "type": "text",
                    "text": "Describe this image."
                },
                {
                    "type": "image_url",
                    "image_url": {
                        "url": f"data:image/jpeg;base64,{image_data}"
                    }
                }
            ]
        }
    ],
    "max_tokens": 2048
}

# Make the API request
[response](/posts/how-to-use-ai-for-cold-email-outreach-2026) = requests.post(endpoint, headers=headers, json=payload)

# Print the response
print(response.json())
