Sample output from Chroma

About

Chroma is an ~8.9-billion-parameter, fully uncensored text-to-image model derived from Black Forest Labs' FLUX.1-schnell and released under the permissive Apache-2.0 license. It's open-weights and community-trained by Lodestone Rock — no content filters, no corporate moderation layer, and free to use, modify, and build on.

Chroma ships in two calibrations: v.46 [flash] runs a fast ten-step schedule for exploration, and v.48 [detail] runs a detail-calibrated twenty-six-step schedule for texture-rich, print-ready output. Both share the same uncensored base and strong anatomy, hands, and prompt adherence.

Use flash to explore, detail for the keeper.

Variants

Chroma ships in 2 builds — same family, different speed/quality trade-offs. Pick the variant that fits, or start with the default.

Variant Steps From

API

One Sogni API key reaches every model on the Supernet — call Chroma 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: 'chroma-v48-detail-svd_fp8',
  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" \
  -H "Authorization: Bearer $SOGNI_API_KEY" \

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.

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

FAQ

Chroma on Sogni

Is Chroma uncensored?

Yes. Chroma ships with no built-in content filters and no corporate moderation layer — it is an open-weights model suited to mature, artistic, and experimental work. You are still responsible for following Sogni’s Terms of Service and applicable law when you generate.

What is Chroma based on?

Chroma is derived from Black Forest Labs' FLUX.1-schnell and released under the permissive Apache-2.0 license, which allows commercial use. It is community-trained by Lodestone Rock and distributed as open weights at roughly 8.9 billion parameters.

What's the difference between Chroma flash and detail?

Both are the same Chroma model at different step schedules. v.46 [flash] runs about ten steps for fast exploration; v.48 [detail] runs about twenty-six steps for texture-rich, print-ready final renders. Use flash to explore, detail for the keeper.

Is it really unlimited on Sogni?

Yes — covered jobs are credit-free under fair use. There are no per-image credits to buy, though 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.

Can I use Chroma commercially?

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