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.
If enabled, the output will be encoded into a BASE64 string instead of a URL. This property is only available through the API.

Idle

Wong Kar-wai film style, a lonely man smoking a cigarette in a narrow Hong Kong hallway, 1990s. Greenish fluorescent lighting, heavy shadows, moody atmosphere. Slight motion blur to create a dreamlike quality. Film grain, vignetting, emotional, cinematic composition, dutch angle shot.

Your request will cost $0.005 per run.

For $1 you can run this model approximately 200 times.

Cinematic wide shot of a battle-worn viking warrior standing in a blizzard. Wearing intricate silver armor with fur cloak. Face covered in mud and war paint. Snowflakes landing on eyelashes. Intense gaze, screaming. Epic mountain background, overcast sky, desaturated colors, gritty texture, highly detailed armor, 8k, Arri Alexa camera.
Retro 90s shojo manga style. Close-up of a girl with sparkling watery eyes and windblown hair. A clean white speech bubble next to her face. The text inside the bubble explicitly reads "I LOVE WaveSpeedAI". Soft dreamy atmosphere, starry background, delicate linework, vintage anime aesthetic.

Z-Image-Turbo — 6B-parameter, ultra-fast text-to-image

Z-Image-Turbo is a 6B-parameter text-to-image model from Tongyi-MAI, engineered for production workloads where latency and throughput really matter. It uses only 8 sampling steps to render a full image, achieving sub-second latency on data-center GPUs and running comfortably on many 16 GB VRAM consumer cards.

Ultra-fast generation with production-ready quality

Where many diffusion models need dozens of steps, Z-Image-Turbo is aggressively optimised around an 8-step sampler. That keeps inference extremely fast while still delivering photorealistic images and reliable on-image text, making it a strong fit for interactive products, dashboards, and large-scale backends—not just offline batch jobs.

Why it looks so good?

• Photorealistic output at speed Generates high-fidelity, realistic images that work for product photos, hero banners, and UI visuals without multi-second waits.

• Bilingual prompts and text Understands prompts in English and Chinese, and can render multilingual text directly in the image—helpful for cross-market campaigns, posters, and screenshots.

• Low-latency, low-step design Only 8 function evaluations per image deliver extremely low latency, ideal for chatbots, configuration tools, design assistants, and any “click → image” experience.

• Friendly VRAM footprint Runs well in 16 GB VRAM environments, reducing hardware costs and making local or edge deployments more realistic.

• Scales for bulk generation Its efficiency makes large jobs—catalogues, continuous feed images, or auto-generated thumbnails—practical without blowing up compute budgets.

• Reproducible generations A controllable seed parameter lets you recreate a previous image or generate small, controlled variations for brand safety and experimentation.

How to use

  • prompt – natural-language description of the scene, style, and any on-image text (English or Chinese).
  • size (width / height) – choose the output resolution; supports square and rectangular images up to high resolutions (for example, 1536 × 1536).
  • seed – set to -1 for random results, or use a fixed integer to make outputs reproducible.
