Ultra-photorealistic lifestyle photo of a young woman working late in a modern Shanghai apartment at night. A sleek silver laptop is open on a wooden desk, next to a minimalist white ceramic mug with faint steam rising. Warm orange indoor light mixes with cool blue city lights from a large window behind her, showing a soft-focus skyline and neon signs. Natural skin texture, detailed hair strands, realistic reflections in the laptop screen and on the table, accurate soft shadows, global illumination, shallow depth of field.
Minimal vertical poster with a clean dark background. Big bold Chinese title at the top: “PiAPI 2025 生成式未来高峰论坛”. Small English subtitle below: “GENERATIVE FUTURE SUMMIT 2025”. A single glowing abstract sphere in the center made of blue and purple light trails.

Top-right panel: “SUMMER / 夏天”, bright sun, lush green trees, the couple sharing ice cream, vivid colors.

By Alibaba, Z-Image Turbo is the core image generation model under the Z-Image model. It is designed specifically for generating high-quality images via API. Image editing is supported separately through the Z-Image Editing variant. Start creating with Z Image Turbo API today!
Z-Image Turbo focuses on image generation from prompts, while Z-Image Editing is designed for modifying existing images. Both models are variants of the Z-Image model and serve different use cases.
You can generate images using PiAPI's Z Image API endpoint by sending a text prompt and configuration parameters. Documentation includes full request examples and integration guides.
Z-Image Edit is still in the process of being released. If you require image editing workflows, please explore other PiAPI image APIs such as Qwen Image API or Nano Banana Pro API that support edit operations.
