+
+> Juggernaut XL Lightning is the **speed-optimized** member of the Juggernaut family — built on **SDXL Lightning** distillation, it produces photo-grade Juggernaut output in just **5–7 inference steps** instead of the usual 30–40. Same aesthetic, ~5× faster, ideal for batch generation, real-time iteration, and live demos.
+
+## When to Use It
+
+- ⚡ **Batch generation** — render hundreds of variations in the time you'd usually generate a few.
+- 🔁 **Real-time iteration** — preview prompt changes in seconds, not minutes.
+- 💻 **Lower-end hardware** — fewer steps means lower VRAM pressure during inference.
+- 🎤 **Live demos and showcases** — instant turnaround when latency is the bottleneck.
+
+If you need the very best per-image quality and don't mind the wait, use [**Juggernaut XL v9**](https://huggingface.co/RunDiffusion/Juggernaut-XL-v9) instead — full-step inference holds slightly more detail.

+
+<h3>⚡ Want speed without setup? Run Lightning on RunDiffusion.</h3>
+
+<p>Pre-loaded with the right scheduler, sampler, and CFG. <b>No installs. No GPU rental.</b></p>
+
+<a href="https://app.rundiffusion.com/login?utm_source=huggingface&utm_medium=model_card&utm_campaign=juggernaut_xl_lightning&utm_content=midpage_cta"><img alt="Launch on RunDiffusion" src="https://img.shields.io/badge/%E2%96%B6%20Launch%20on%20RunDiffusion-7C3AED?style=for-the-badge&labelColor=7C3AED"></a>
+
+<p><i>Pre-loaded into ComfyUI · Forge · Automatic1111 · Fooocus · InvokeAI · SwarmUI</i></p>
+
+</div>
+
+---
+
+## Recommended Settings
+
+> **These are different from standard Juggernaut.** Lightning needs fewer steps and lower CFG.
+
+| Parameter | Value |
+| --- | --- |
+| Sampler | `DPM++ SDE` or `DPM++ SDE Karras` |
+| Steps | `5 – 7` |
+| CFG scale | `1.5 – 2.0` |
+| Resolution | `≥ 1024 × 1024` (use SDXL-native sizes) |
+| VAE | **Already baked in** — no external VAE required |
+
+Standard Juggernaut prompts work as-is. Don't adjust your prompt for Lightning — just adjust the sampler, steps, and CFG.
+
+📖 **Want to go deeper on prompting?** See the [**RunDiffusion prompting library**](https://www.rundiffusion.com/prompting?utm_source=huggingface&utm_medium=model_card&utm_campaign=juggernaut_xl_lightning&utm_content=prompting_inline). Free to read, no signup.
+
+## Two Ways to Run Juggernaut XL Lightning
+
+### 🚀 Easiest — Run it on RunDiffusion (recommended)
+
+One-click access inside ComfyUI, Forge, Automatic1111, Fooocus, InvokeAI, or SwarmUI. **Free trial included**, plus access to every other Juggernaut model on the same account.
+
+<div align="center">
+  <a href="https://app.rundiffusion.com/login?utm_source=huggingface&utm_medium=model_card&utm_campaign=juggernaut_xl_lightning&utm_content=quickstart_try"><img alt="Get Started Free" src="https://img.shields.io/badge/Get%20Started%20Free%20%E2%86%92-7C3AED?style=for-the-badge&labelColor=7C3AED"></a>
+</div>
+
+### 💻 Or run it locally — Diffusers
+
+```python
+import torch
+from diffusers import DiffusionPipeline, DPMSolverSinglestepScheduler
+
+pipe = DiffusionPipeline.from_pretrained(
+    "RunDiffusion/Juggernaut-XL-Lightning",
+    torch_dtype=torch.float16,
+    use_safetensors=True,
+).to("cuda")
+
+# DPM++ SDE Karras
+pipe.scheduler = DPMSolverSinglestepScheduler.from_config(
+    pipe.scheduler.config, use_karras_sigmas=True
+)
+
+prompt = "Cinematic mid shot photo of an astronaut walking through a neon-lit Tokyo alley at night, hyperdetailed photography, skin details, shallow depth of field"
+
+image = pipe(prompt, width=1024, height=1024, num_inference_steps=6, guidance_scale=1.8).images[0]
+image.save("juggernaut_xl_lightning.png")
+```
+
+For ComfyUI / Forge / InvokeAI / SwarmUI: download the single-file checkpoint and drop it into your `models/checkpoints/` directory.
