Flux 2.0 image generation model
Choose flux-2-flex (faster, for quick iteration) or flux-2-pro (higher quality, better details) via the model parameter
Supports text-to-image and image-to-image, up to 8 reference images
Billed by resolution (1K/2K)
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

기본값:"1:1"

Image aspect ratioSupported aspect ratios:

1:1 - Square (default)
4:3 / 3:4 - Traditional display ratio
16:9 / 9:16 - Widescreen/portrait
3:2 / 2:3 - Standard photo

string[]

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

Metadata parameters for additional configuration options

표시 Supported metadata fields

string

기본값:"1K"

Output image resolutionOptions:

1K - Standard resolution (default)
2K - High resolution

Resolution vs. aspect ratio pixel dimensions:

Aspect Ratio	1K Size	2K Size
1:1	1024×1024	2048×2048
4:3	1365×1024	2730×2048
3:4	1024×1365	2048×2730
16:9	1820×1024	3640×2048
9:16	1024×1820	2048×3640
3:2	1536×1024	3072×2048
2:3	1024×1536	2048×3072

Note: Different resolutions have different billing; 2K costs more than 1K.
