Flux Kontext image generation and editing model
Choose flux-kontext-pro (Pro) or flux-kontext-max (Max, higher quality) via the model parameter
Supports text-to-image and image editing modes
With reference image = image editing; without = text-to-image
Fixed billing per request
Async task mode, returns task_id for querying results

Important Change: For better performance and cost control, we no longer support passing base64 image data directly in image_urls. Please use the Upload 이미지 API first to upload images and get URLs, then call this endpoint.

Text description for image generation

string

Image aspect ratioDefault:

With reference image: match_input_image (match input image)
Without reference image: 16:9

Supported aspect ratios:

Value	설명
`match_input_image`	Match input image ratio (image editing only)
`1:1`	Square
`4:3` / `3:4`	Traditional display ratio
`16:9` / `9:16`	Widescreen/portrait
`3:2` / `2:3`	Standard photo
`21:9` / `9:21`	Ultrawide/ultra-narrow

string[]

Reference image URL array for image editing⚠️ URL format only (base64 not supported)

Publicly accessible image URL (http:// or https://)

  "model": "flux-kontext-pro",
  "prompt": "Cyberpunk city at night, neon lights flickering",
  "size": "16:9",
  "metadata": {
    "response_format": "png",
    "safety_tolerance": 2
  }
}

Case 2: Image Editing

{
  "model": "flux-kontext-max",
  "prompt": "Transform this photo into watercolor style",
  "size": "match_input_image",
  "image_urls": ["https://example.com/photo.jpg"],
  "metadata": {
    "response_format": "jpg",
    "prompt_upsampling": true
  }
}

Case 3: High-Quality Text-to-Image (Max 모델)

  "size": "1:1",
  "metadata": {
    "response_format": "png",
    "safety_tolerance": 3
  }
}

Query Task ResultsImage generation is an async task. After submission, a task ID is returned. Use the Get Image Task 상태 endpoint to query generation progress and results.
