# Z-Image-Turbo LoRA — Atlas Cloud API

> Z-Image Turbo text-to-image generation with user-supplied LoRA weights, custom sizes, and reproducible output.

This is the machine-readable API reference for **Z-Image-Turbo LoRA** on Atlas Cloud,
a unified API platform for 400+ AI models across text, image, video, audio and 3D.

- **Model ID**: `z-image/turbo-lora`
- **Built by**: Atlas Cloud
- **Modality**: Image
- **Model page**: https://www.atlascloud.ai/models/z-image/turbo-lora
- **API key**: https://www.atlascloud.ai/console/api-keys
- **Docs**: https://www.atlascloud.ai/docs

## Pricing on Atlas Cloud

- $0.01 per image
- Pay-as-you-go. No minimum spend, no subscription required.

> **These are the authoritative Atlas Cloud rates for this model.** Any price that
> appears in the vendor description further down refers to a different platform or
> a different model variant and does not apply here.

## Use this model from an AI agent

Atlas Cloud ships three first-party integration surfaces. All three authenticate
with the same API key via the `ATLASCLOUD_API_KEY` environment variable.

### MCP server

The official MCP server (`atlascloud-mcp`) exposes this model to any
MCP-compatible host — Claude Code, OpenAI Codex, Cursor, Gemini CLI, Goose,
Claude Desktop. One-line install:

```bash
# Claude Code
claude mcp add atlascloud -- npx -y atlascloud-mcp

# OpenAI Codex CLI
codex mcp add atlascloud -- npx -y atlascloud-mcp

# Gemini CLI
gemini mcp add atlascloud -- npx -y atlascloud-mcp

export ATLASCLOUD_API_KEY="your-api-key"
```

Then ask in plain English; the agent calls `atlas_generate_image` with `model: "z-image/turbo-lora"`.
The server fetches each model's schema and validates parameters before submitting,
so invalid requests fail fast without spending credits.

### Agent Skills

`atlas-cloud-skills` is a portable skill package (API reference, code templates in
Python / Node.js / cURL, model IDs with pricing) for Claude Code, Cursor, Codex and
12+ other agents:

```bash
npx skills add AtlasCloudAI/atlas-cloud-skills
export ATLASCLOUD_API_KEY="your-api-key"
```

Skills docs: https://www.atlascloud.ai/docs/skills

### CLI

The `atlas` binary runs Atlas Cloud from a terminal or CI script. Async media jobs
are polled and downloaded automatically (use `--no-download` when a script only
needs the output URLs):

```bash
# Install (Homebrew, npm, or shell installer)
brew install AtlasCloudAI/tap/atlascloud
# npm install -g atlascloud-cli
# curl -fsSL https://raw.githubusercontent.com/AtlasCloudAI/cli/main/install.sh | sh

atlas auth login
atlas generate image z-image/turbo-lora -p "Your prompt here"
```

  - Default: `false`



**Required Parameters Example**:

```json
{
  "model": "z-image/turbo-lora",
  "prompt": ""
}
```


**Full Example**:

```json

## About this model

_Vendor-supplied description. Any pricing or endpoint mentioned below refers to_
_other platforms — use the Atlas Cloud values above._

#### Z-Image-Turbo LoRA — 6B-parameter, ultra-fast text-to-image with custom styles

**Z-Image-Turbo LoRA** is a personalised version of Tongyi-MAI’s 6B-parameter **Z-Image-Turbo** model. It keeps the same **8-step, ultra-fast sampler** and low VRAM footprint, while letting you plug in up to **three LoRA adapters** to inject your own styles, characters, or brand identity into each generation.

#### Ultra-fast generation with LoRA personalisation

Where many diffusion models need dozens of steps, **Z-Image-Turbo LoRA** stays aggressively optimised around 8 sampling steps. On top of that, it adds LoRA hooks so you can steer the visual style without retraining the base model—perfect for interactive products, dashboards, and large-scale backends that still need a branded look.

##### Why it looks so good

**• Photorealistic output at speed** Generates high-fidelity, realistic images suitable for product photos, hero banners, and UI visuals—now with your own LoRA styles layered on top.

**• Bilingual prompts and text** Understands prompts in **English and Chinese**, and can render multilingual on-image text, ideal for cross-market campaigns and UI screenshots.

**• LoRA-powered customisation** Attach up to **3 LoRAs per request** to add a specific art style, character look, or brand aesthetics without touching the base weights.

**• Low-latency, low-step design** Only **8 function evaluations** per image deliver extremely low latency, ideal for chatbots, configuration tools, design assistants, and any “type → image” workflow.

**• Friendly VRAM footprint** Runs well in **16 GB VRAM** environments, reducing hardware costs and making local or edge deployments more realistic—even with LoRAs enabled.

**• Scales for bulk generation** The efficient sampler keeps large jobs—catalogues, continuous feeds, or mass thumbnail generation—practical, even when every image uses one or more LoRAs.
