Sample output from Z-Image Turbo

About

Z-Image Turbo is the workhorse of the Supernet: a turbo-distilled checkpoint that turns a prompt into a 1024-pixel image in four steps, typically inside ten seconds. At 0.8 Spark per render it is the cheapest way to iterate on an idea — and the model every new account can run on free monthly Spark.

Quality holds up well beyond its price class. Use it for drafts, batch exploration, and anything where iteration speed beats final-grade polish; graduate to Z-Image or FLUX.2 [dev] when you need maximum fidelity.

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 Turbo and 100+ other models credit-free under fair use.

Configuration Spark USD
1024 × 1024 · 4 steps 0.80 Spark $0.004
2048 × 2048 · 4 steps (scales with pixels) 3.20 Spark $0.016

API

One Sogni API key reaches every model on the Supernet — call Z-Image Turbo 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_turbo_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 Turbo by id and pay in Spark.

FAQ

Z-Image Turbo on Sogni

What is Z-Image Turbo?

Z-Image Turbo is a fast, open-source text-to-image model from Alibaba's Tongyi-MAI lab. It produces photorealistic images in roughly eight steps, ranks at the top of open text-to-image leaderboards, and renders legible text (including English and Chinese) inside images. It's released under the permissive Apache-2.0 license.

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 Turbo 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 Turbo 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.

Do I need a GPU or ComfyUI?

No. Z-Image Turbo runs on Sogni's decentralized GPU network and generates right in your browser or the Sogni app — no local install, no nodes, no graphics card required.
