SD XL

About

SD XL is a SDXL community image model available on the Sogni Supernet — generate credit-free under fair use, no GPU or setup required. Stable Diffusion XL (SDXL) is a powerful image generation model from Stability AI that produces highly detailed, more photorealistic results than earlier Stable Diffusion models. It works well with shorter prompts, offers stronger composition and face generation, and handles text in images better than previous versions—making it a versatile choice for both realistic and stylized visuals. SDXL also remains one of the most popular models in the open-source community, with a large ecosystem of fine-tunes and variation models built for unique creative styles and capabilities. This gives you a wide selection of high-quality SDXL-based models to choose from, each with its own strengths for different looks and workflows.

It ships in 2 versions (v1.0, v1.0 with Refiner); pick a version below, or use the default.

Variants

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

Pricing

SD XL is included on every Sogni plan — generate credit-free under fair use, alongside 100+ other models, from a flat monthly price.

API

One Sogni API key reaches every model on the Supernet — call SD XL 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: 'coreml-stable-diffusion-xl-base',
  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
