Sample output from Z-Image

About

Z-Image is the quality tier of the Z-Image line: the same architecture as Turbo, run at full step counts for sharper detail, cleaner texture, and better adherence on dense prompts.

It sits at the same price point as FLUX.2 [dev] and Qwen Image 2512 — pick between them by aesthetic preference; all three are strong general-purpose flagships.

Pricing

Use pay-as-you-go Spark packs for each render (1 Spark = $0.005), or choose a flat-rate Sogni plan for credit-free fair-use generation in the app.

API

One Sogni API key reaches every model on the Supernet — call Z-Image with the exact model id.

import { SogniClient } from '@sogni-ai/sogni-client';

const client = await SogniClient.createInstance({
  appId: crypto.randomUUID(),
  apiKey: process.env.SOGNI_API_KEY,
  network: 'fast',
});

const project = await client.projects.create({
  type: 'image',
  modelId: 'z_image_bf16',
  positivePrompt: 'a slothicorn surfing a wave of liquid paint, studio lighting',
  numberOfMedia: 1,
});

const [url] = await project.waitForCompletion();
console.log(url); // result link — download within 24h
curl https://api.sogni.ai/v1/creative-agent/workflows \

FAQ

Z-Image on Sogni

What is Z-Image?

Z-Image is the full-capacity, undistilled open-source text-to-image model from Alibaba's Tongyi-MAI lab — the foundation of the Z-Image family. The standard variant favors maximum fidelity, taking more sampling steps than Z-Image Turbo for the highest-quality, most detailed photorealistic output, and it renders legible text (including English and Chinese) inside images. It's released under the permissive Apache-2.0 license.

How is Z-Image different from Z-Image Turbo?

Same family, different trade-off. Z-Image Turbo is distilled for speed — photorealistic images in roughly eight steps. Standard Z-Image is the undistilled, full-capacity model: it takes more sampling steps to favor maximum fidelity and the most detailed output. Both are on Sogni and both are credit-free fair-use, so you can pick the right one per job.

Is it really unlimited?

Yes — covered jobs are credit-free under fair-use. There are no per-image credits to buy, but active-job concurrency, generate queue limits, and fair-use controls apply. Covered jobs run on Sogni's shared GPU network and may queue during peak demand; heavy-usage based throttles reset each UTC day.

How much does it cost?

Sogni offers both subscription plans and Pay-As-You-Go Spark packs. Sogni Unlimited is $20/month (or $199/year), Unlimited Pro is $50/month (or $498/year), and Spark packs let you pay per eligible render without a subscription. Every plan starts with a 3-day free trial and you can cancel anytime.

Can I use long, detailed prompts?

Absolutely — Z-Image follows long, structured prompts faithfully. The examples above show complete, unedited prompts (some several hundred words) and the exact image each produced. Hit "Use prompt" to load the full prompt into the app and reproduce or remix it.

Can I use the images commercially?

Z-Image is Apache-2.0 licensed, which permits commercial use of what you create. Always review the current model and Sogni terms for the specifics of your use case.

How private is my use of this model on Sogni?

Sogni is built with privacy and creative freedom in mind. Your work remains your own, and inference runs through the Sogni Supernet, a decentralized network of creator GPUs, instead of requiring local hardware or a separate model host. Use is still governed by Sogni's Privacy Policy and Terms of Use.
