Overview

What the Grok Image API does

xAI's Grok Imagine image model in two tiers. Generates or edits from up to 3 reference images while keeping the source's details intact. xAI's safety filter applies.

xAI's Grok Imagine image models in two tiers, for generation and edits from reference images: Grok Image 2.0 (`grok-imagine-image-2.0`), the default, and Grok Image (`grok-imagine-image`) for cheap drafts. xAI retired Grok Image Quality (`grok-imagine-image-quality`) on November 2, 2026, and a request that names it is refused. xAI's safety filter applies.

It accepts image, additional_images as inputs.

Quick start

Call the Grok Image API

Set MAGE_API_KEY, submit to /grok_image/generate, and poll status_url until the request completes.

STATUS_URL=$(curl --request POST 'https://api.mage.space/v1/grok_image/generate' \
  --header "Authorization: Bearer $MAGE_API_KEY" \
  --header 'Content-Type: application/json' \
  --data '{
  "prompt": "Editorial portrait in soft daylight, 35mm film look",
  "aspect_ratio": "1:1",
  "model_id": "grok-imagine-image-2.0"
}' | jq -r '.status_url')

# Repeat until status is "completed"; result.url is the file
curl "$STATUS_URL" --header "Authorization: Bearer $MAGE_API_KEY"
TypeScript
// npm install @mage-space/sdk
import Mage from '@mage-space/sdk';

const mage = new Mage(); // reads MAGE_API_KEY

const request = await mage.run('grok_image', {
  prompt: 'Editorial portrait in soft daylight, 35mm film look',
  aspect_ratio: '1:1',
  model_id: 'grok-imagine-image-2.0',
});

console.log(request.result.url);
Python
# pip install mage-space
from mage_space import Mage

mage = Mage()  # reads MAGE_API_KEY
