Parameters

Parameter	Required	Description
prompt	Yes	Text description of the image you want to generate.
size	No	Custom dimensions with separate width and height controls.
width	No	Output width in pixels (e.g., 1328).
height	No	Output height in pixels (e.g., 1328).
seed	No	Random seed for reproducibility. Use -1 for random.
enable_prompt_expansion	No	API only: Waits for image generation and returns it directly in the response.

How to Use

Write your prompt — describe your image with details about subject, style, lighting, and atmosphere.
Use Prompt Enhancer (optional) — click to automatically enrich your description.
Set dimensions — adjust width and height sliders to your desired resolution and aspect ratio.
Set seed (optional) — use -1 for random, or a specific number to reproduce results.
Run — click the button to generate.
Download — preview and save your image.

Pricing

Flat rate per image generation.

Example Prompts

“A painter working in a sunlit studio, large canvas filled with abstract colors, brushes and paint tubes scattered on the floor, creative atmosphere”
“Cozy coffee shop corner with vintage furniture, morning light streaming through large windows, steam rising from a ceramic cup”
“Futuristic city rooftop garden at golden hour, glass skyscrapers in background, lush green plants contrasting with urban architecture”
“Portrait of a jazz musician mid-performance, dramatic stage lighting, saxophone gleaming, smoky club atmosphere”
“Serene Japanese zen garden with raked sand patterns, moss-covered stones, soft morning mist, minimalist aesthetic”

Pro Tips for Best Results

Include atmosphere and mood — “creative atmosphere”, “warm lighting”, “dramatic shadows”.
Describe environmental details — objects, textures, and spatial relationships.
Use the Prompt Enhancer to add professional details to simple ideas.
Square dimensions (1328×1328) work well for balanced compositions.
Adjust dimensions to match your platform: tall for Stories, wide for headers, square for feeds.
Keep the seed constant when testing prompt variations to isolate changes.

Notes

The enable_prompt_expansion option is only available through the API.
Generation time may vary based on resolution and current queue load.
Higher resolutions produce more detailed results but may take slightly longer.

Request Parameters

Parameter	Type	Required	Default	Range	Description
prompt	string	Yes		-	The positive prompt for the generation.
size	string	No	1328*1328	512 ~ 2048 per dimension	The size of the generated media in pixels (width*height).
seed	integer	No	-1	-1 ~ 2147483647	The random seed to use for the generation. -1 means a random seed will be used.
enable_prompt_expansion	boolean	No	true	-	If set to true, the function will wait for the image to be generated and uploaded before returning the response. It allows you to get the image directly in the response. This property is only available through the API.
enable_base64_output	boolean	No	false	-	If enabled, the output will be encoded into a BASE64 string instead of a URL. This property is only available through the API.
enable_sync_mode	boolean	No	false	-	If set to true, the function will wait for the result to be generated and uploaded before returning the response. It allows you to get the result directly in the response. This property is only available through the API.
