z_image_bf16 The full-step sibling of Turbo — same model line, maximum detail.
No GPU. No setup. Cancel anytime.
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.
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.

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

Real generations from Sogni. Hit Use prompt to open the app with Z-Image selected and the full prompt preloaded.
Use a flat monthly plan for credit-free fair-use generation, or buy Spark packs when pay-as-you-go fits better. Both run on the same creator-owned GPU network.
One flat price in the app. Generate under fair use without a per-image meter.
Image, video, music, and language models in one workspace and one API key.

Runs on a decentralized GPU network where workers share subscription revenue.
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.
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.
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.
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.
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.
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.
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.
Create in the app, or build with the API. Your call.
