Using Image URLs

from openai import OpenAI

client = OpenAI(
    api_key="sk-samurai-YOUR_KEY",
    base_url="https://api.samuraiapi.in/v1"
)

response = client.chat.completions.create(
    model="gpt-4o",
    messages=[
        {
            "role": "user",
            "content": [
                {
                    "type": "image_url",
                    "image_url": {"url": "https://upload.wikimedia.org/wikipedia/commons/thumb/3/3a/Cat03.jpg/1200px-Cat03.jpg"}
                },
                {
                    "type": "text",
                    "text": "What is in this image? Describe it in detail."
                }
            ]
        }
    ]
)

print(response.choices[0].message.content)

​
Using Base64 Images

import base64

with open("screenshot.png", "rb") as f:
    image_data = base64.b64encode(f.read()).decode("utf-8")

response = client.chat.completions.create(
    model="gpt-4o",
    messages=[
        {
            "role": "user",
            "content": [
                {
                    "type": "image_url",
                    "image_url": {
                        "url": f"data:image/png;base64,{image_data}"
                    }
                },
                {"type": "text", "text": "Extract all text from this screenshot."}
            ]
        }
    ]
)

​
Multiple Images

response = client.chat.completions.create(
    model="gpt-4o",
    messages=[
        {
            "role": "user",
            "content": [
                {"type": "image_url", "image_url": {"url": "https://example.com/before.jpg"}},
                {"type": "image_url", "image_url": {"url": "https://example.com/after.jpg"}},
                {"type": "text", "text": "What changed between these two images?"}
