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

On the Sogni API you pay per render in Spark (1 Spark = $0.005). Prefer a flat rate? The Sogni app runs Z-Image and 100+ other models credit-free under fair use.

API

One Sogni API key reaches every model on the Supernet — call Z-Image by 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 \
  -H "Content-Type: application/json" \

Why run it on Sogni

Unlimited, not metered

Most platforms ration credits or rent a cloud GPU by the hour. Sogni gives you a flat monthly price for credit-free fair-use generation, powered by a creator-owned GPU network — or per-render Spark pricing if you'd rather pay as you go via the API.

No credits, ever

One flat price in the app. Generate under fair use without a per-image meter.

🧩

100+ models

Image, video, music, and language models in one workspace and one API key.

Per-render API

Prefer pay-as-you-go? Call Z-Image by id and pay in Spark.

Runs on a decentralized GPU network where workers share subscription revenue.

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 Unlimited is $20/month (or $199/year). Unlimited Pro is $50/month (or $498/year) and adds higher throughput, higher queue priority, and larger supported outputs where available. 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.
