size
Exact pixel dimensions
"1920x1080"
aspect_ratio
Shape only, default scale
"16:9"
resolution
Scale tier, preserves shape
"1K"
size is most specific and always wins. aspect_ratio and resolution control shape and scale independently.
7:1 on a model with
4:1 and 8:1,
you get 8:1.
0.5K 1K 2K 4K)
or megapixel tiers (0.25 1).
If the exact tier isn't available, you get the nearest one.
These work the same regardless of which provider runs your request
response_format
url or
b64_json.
If you ask for a URL but the provider returns base64, we store it temporarily and hand you a link valid for 60 minutes.
output_format
Pick from png
jpeg
gif
webp
avif.
We convert if the provider generates a different format.
output_compression
Quality level from 1 to
100 for lossy formats (jpeg, webp, avif).
Higher means better quality, larger file.
n
Request multiple images in one call. If the provider caps at 1, we run parallel requests behind the scenes and return them together.
Not every provider speaks the same language. When you send a parameter, we handle it in one of four ways depending on what the model supports:
| Mode | What happens | Example |
|---|---|---|
passthrough |
Sent as-is to the provider | style, quality |
renamed |
Same value, mapped to the field name the provider expects | prompt |
converted |
Transformed to the provider's native format | size |
emulated |
Works even if the provider has no concept of it | n, response_format |
Parameters we don't recognize pass straight through to the upstream API, so provider-specific options still work.

Z-Image Turbo excels in commercial applications, ranking 5th in product and branding with a 55.6% win rate and 7th in portrait generation with a 62.5% win rate. It demonstrates moderate performance in bilingual text rendering but faces significant challenges in specialized photorealism and portrait-specific arena categories.
Z-Image Turbo starts at $0.005 per image through Lumenfall. Pricing varies by provider. Lumenfall does not add any markup to provider pricing.
You can use Z-Image Turbo through Lumenfall's OpenAI-compatible API. Send requests to the unified endpoint with model ID "z-image-turbo". Code examples are available in Python, JavaScript, and cURL.
Z-Image Turbo is available through fal.ai, Alibaba Cloud, and Replicate on Lumenfall. Lumenfall automatically routes requests to the best available provider.
Z-Image Turbo supports images up to 2048x2048 resolution.
Z-Image Turbo is a 6-billion parameter text-to-image model developed by Alibaba’s Tongyi-MAI team. It distinguishes itself by utilizing distillation techniques to enable high-quality image synthesis in eight steps or fewer, making it significantly faster than standard diffusion models. The model is specifically optimized for bilingual text rendering, supporting both Chinese and English characters within generated imagery.
Z-Image Turbo is part of the Z-Image model family and utilizes a distilled architecture derived from a larger latent diffusion framework. To achieve its speed, the developers employed a consistency-based distillation approach that maps the probability flow of the original model into a single or few-step inference trajectory. The integration of a specialized text encoder allows the model to handle bilingual tokens more effectively than models trained solely on English datasets.
This model is ideal for interactive applications such as live drawing assistants, rapid prototyping for UI/UX design, and social media content creation where speed is prioritized over granular control. It is also a leading choice for projects requiring accurate Chinese typography within images. Z-Image Turbo is available for integration and testing through Lumenfall’s unified API and interactive playground.
