Z Image Turbo – Sub-Second AI Image Generation
Tongyi's 6 billion parameter text-to-image model that generates photorealistic images in sub-second time. Optimized for speed without sacrificing quality.
Frequently asked questions
What is Z Image Turbo?
A 6B parameter text-to-image model from Tongyi-MAI, optimized using compression, caching, and quantization. It generates photorealistic images in sub-second time with accurate bilingual text rendering.
Why is it so fast?
The model uses Decoupled-DMD (Distribution Matching Distillation) to compress a larger model into a faster one, with caching, compilation, and quantization optimizations—8 steps is all it needs.
How good is the text rendering?
One of its standout features. It renders text accurately in both English and Chinese—great for posters, signage, book covers, labels, UI mockups, and diagrams.
What makes this model different?
Speed plus quality. Most fast models sacrifice detail, but Z Image uses a Single-Stream Diffusion Transformer that processes text and image together efficiently.
When should I use Z Image?
Quick iterations: Perfect for rapid prototyping and exploring ideas.
Text in images: Clear Chinese or English text rendering.
Photorealistic results: Natural lighting and realistic textures.
Cost-effective: Generate lots of quality images fast.
How do I write good prompts?
Be specific: Describe subject, style, lighting, and mood in detail.
Include style keywords: 'photorealistic', 'cinematic', 'golden hour', 'studio lighting'.
For text rendering: State exact wording and where it should appear.
Optimal settings: Best results at 1024x1024 resolution.
What aspect ratios are supported?
1:1, 16:9, 9:16, 4:3, 3:4, 3:2, and 2:3. The model auto-calculates dimensions based on your choice (minimum: 64px, maximum: 2048px).
What are Z Image's key features?
Photorealistic quality: Natural lighting, realistic textures, believable scenes.
Bilingual text rendering: Accurate English and Chinese for posters, labels, mockups.
Fast generation: Sub-second results with just 8 steps.
Efficient architecture: Single-Stream Diffusion Transformer.
