Python SDK

import xai_sdk

client = xai_sdk.Client()
response = client.image.sample(
    prompt="A futuristic city skyline",
    model="grok-imagine-image-quality",

print(response.url)

OpenAI SDK Compatible

from openai import OpenAI

client = OpenAI(
    base_url="https://api.x.ai/v1",
    api_key="YOUR_XAI_API_KEY",

Tips

• URLs are temporary — download promptly
• Use b64_json for embedding
• Use n parameter for batch variations
• Use async for concurrent different prompts
• Check respect_moderation for content filtering
