Input

prompt *

Create a horizontal 3:2 botanical art poster photographed directly from above. On a rich cobalt-blue matte surface, arrange fresh flowers into the exact readable phrase "Kie AI". The letters themselves are physical floral sculptures, not printed text and not typography placed over an image.

Build the letterforms from densely arranged coral-orange ranunculus, pale peach carnations, and small cream chrysanthemums. Use flower heads of different sizes to create deliberate thick and thin strokes while preserving clean, recognizable letter shapes. Preserve the exact capitalization: uppercase K, lowercase i and e, followed by a clear space, then uppercase A and I. Keep the counters and gaps open so the phrase reads immediately.

Make the floral lettering the dominant central subject, occupying roughly two-thirds of the image width. Allow a few short stems and delicate leaves to extend naturally beyond the letter edges, with just three or four loose petals nearby. Maintain generous untouched blue space around the arrangement.

Use directional morning sunlight from the upper left to reveal translucent petal edges, tightly layered blooms, and crisp but delicate shadows cast onto the blue surface. Combine the precision of a contemporary exhibition poster with the tactile beauty of real floral craftsmanship. Bold color contrast, elegant spacing, finely resolved botanical details.

Describe the image you want to generate. Any language is supported, up to 5000 characters.1391/5000

aspect_ratio

Output aspect ratio. The actual pixel size also depends on the resolution tier.

resolution

Output resolution tier. Only 1K and 2K are supported. 2K takes noticeably longer to generate.

background

Background type. transparent outputs a PNG or WebP with a real alpha channel and cannot be used with JPEG. When using transparent, describe only the subject — prompts that mention a background, scene, surface, etc. may produce a non-transparent result.

output_format

Output image format. JPEG has no alpha channel, so it cannot be combined with a transparent background.

enhance_prompt

Rewrites the prompt into a fuller scene description before generating, which noticeably improves quality. Enabled by default (also when the parameter is omitted); pass false to turn it off.

seed

The same seed with the same prompt and parameters reproduces the same image on the same model version. The seed actually used is returned with the result.

nsfw_checker

A configurable parameter. Defaults to true in the Playground.
