> Juggernaut XI Lightning is the **speed-optimized** variant of [**Juggernaut XI v11**](https://huggingface.co/RunDiffusion/Juggernaut-XI-v11) — distilled with **SDXL Lightning** for 5–7-step inference. All of XI's improvements (sharper hands, faces, better prompt adherence, native text rendering) at ~5× the speed of standard XI.

## Inherited from XI v11

- 🎨 Massively improved aesthetics over X / earlier versions
- 🖐️ Better hands, eyes, faces, and overall human anatomy
- 🎯 Stronger prompt adherence
- 🔤 Native text rendering for signage, labels, short phrases
- 💬 Two prompting styles: Natural language *or* Tagging
- 🖼️ RunDiffusion Photo refinement

## What Lightning Adds

- ⚡ **5–7-step inference** — generate in a fraction of standard SDXL inference time
- 🔁 **Real-time iteration** — preview prompt changes in seconds
- 💻 **Lower VRAM pressure** during inference

If you need the very best per-image quality, use the [**standard XI v11**](https://huggingface.co/RunDiffusion/Juggernaut-XI-v11) instead.

## Recommended Settings

> Lightning needs different settings from standard XI. Steps low, CFG very low.

| 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 XI prompts work as-is. Just adjust the sampler, steps, and CFG.
