Overview

Z-Image Turbo LoRA API Overview

Z-Image Turbo LoRA delivers ultra-fast text-to-image generation using a 6B-parameter model, enhanced with LoRA adapter support for custom styles. This inference endpoint excels in sub-second photorealistic outputs via optimized 8-step sampling.

Technical Specifications

  • Model Size: 6 billion parameters
  • Sampling Steps: Fixed at 8 for minimal latency
  • LoRA Capacity: Up to 3 adapters simultaneously
  • Prompt Languages: English, Chinese
  • VRAM Requirement: 16 GB (with LoRAs active)
  • Output Quality: High-fidelity photorealism

Performance Benchmarks

  • Generates images in sub-second latency, outperforming multi-step models in interactive scenarios.
  • Handles LoRA stacking without VRAM spikes beyond 16 GB.
  • Excels in bulk processing for thumbnails or feeds.

Key Features

  • Bilingual prompt handling in English and Chinese, with on-image multilingual text rendering for global applications.​
  • LoRA integration for injecting custom styles, characters, or brands while maintaining base speed.​
  • Ultra-low latency via 8-step sampler, ideal for real-time tools like chatbots or design previews.​
  • Photorealistic fidelity suited for product visuals, UI elements, and hero images with vibrant, high-saturation outputs.​
  • Scalable for bulk tasks like catalogs or thumbnails, with safety checker and flexible aspect ratios.

Use Cases

  • E-commerce Visuals: Rapid product mockups with branded LoRAs for catalogs and ads.
  • UI/UX Design: Instant hero banners or app screenshots with custom styles.
  • Interactive Apps: Real-time image gen in chatbots, configurators, or creative dashboards.
  • Marketing Assets: Multilingual campaign graphics blending photorealism and personalization.
  • Content Pipelines: Bulk thumbnails or previews for social media and video thumbnails.

Code Sample

Model Comparisons

vs. Stable Diffusion LoRA: Excels in 8-step speed for sub-second outputs versus Stable Diffusion's 20-50 steps, enabling real-time use cases. LoRA support matches but adds bilingual prompts and lower VRAM needs (16GB viable).

vs. Flux.2: Turbo's 6B efficiency trumps Flux.2's heavier footprint for edge deployments, with comparable photorealism but superior latency. LoRA customization provides style flexibility without full fine-tuning overhead.

vs. DALL·E 3: DALL·E 3 has superior prompt understanding and safety filtering. Z-Image Turbo provides open fine-tuning (via LoRA), lower latency, and transparent commercial terms, ideal for embedded AI products.

Use cases

Z-Image Turbo LoRA is documented for custom style application, including using LoRA weights to steer the visual style without retraining the base model. It is also documented for brand-consistent generation, supporting outputs that match a brand look.

It is documented for character consistency workflows, where specific characters can be kept consistent across generated images. It is also documented for rapid design iteration, supporting fast experimentation with visual concepts and variations.

How to use Z-Image Turbo LoRA API

Install any OpenAI-compatible SDK, point it at api.aimlapi.com/v1, and set the model to z-image/turbo/lora.
import requests

r = requests.post(
    "https://api.aimlapi.com/v1/images/generations",
    headers={"Authorization": "Bearer " + AIMLAPI_KEY},
    json={
      "model": "z-image/turbo/lora",
      "prompt": "A cat holding a sign that says hello"
    },
)
print(r.json())
const r = await fetch("https://api.aimlapi.com/v1/images/generations", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${process.env.AIMLAPI_KEY}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    "model": "z-image/turbo/lora",
    "prompt": "A cat holding a sign that says hello"
  }),
});
console.log(await r.json());
curl -X POST https://api.aimlapi.com/v1/images/generations \
  -H "Authorization: Bearer $AIMLAPI_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"z-image/turbo/lora","prompt":"A cat holding a sign that says hello"}'

OpenAI-compatible — swap the base URL and it works with your existing SDK.
