Juggernaut X Hyper is the Hyper-SD speed variant of Juggernaut X v10. Same ground-up retrain, same GPT-4V-captioned dataset, same RunDiffusion Photo refinement — but distilled for few-step inference. Ideal for batch generation, real-time iteration, and live demos where latency matters more than the last 1% of detail.
Inherited from X v10
- 🧠 Trained from the ground up — not a fine-tune of v9 or earlier
- 👁️ GPT-4 Vision captioning for sharper prompt adherence
- 🔤 Native text rendering for signage, labels, and short phrases
- 📸 Cleaner Full Body / Mid Shot / Portrait shot-type classification
- 💬 Two prompting styles: Natural language or Tagging
What Hyper Adds
- ⚡ Few-step inference — generate in a fraction of standard SDXL inference time
- 💻 Lower VRAM pressure during inference
- 🔁 Real-time iteration — preview prompt changes in seconds
If you need the very best per-image quality and don't mind the wait, use the standard X v10 instead.
Recommended Settings
Hyper-SD distillation needs different settings from standard Juggernaut. Steps low, CFG very low.
| Parameter | Value |
|---|---|
| Sampler | DPM++ SDE or TCD |
| Steps | 4 – 8 (start with 6) |
| CFG scale | 1.0 – 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 Hyper — just adjust the sampler, steps, and CFG.

Two Ways to Run Juggernaut X Hyper
🚀 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.
💻 Or run it locally
For ComfyUI / Forge / InvokeAI / SwarmUI: download the single-file checkpoint and drop it into your models/checkpoints/ directory. Set sampler to DPM++ SDE, steps to 6, and CFG to ~1.5.
The Rest of the Family
| Model | Best for |
|---|---|
| Juggernaut XL v9 | The flagship SDXL — 6M+ downloads |
| Juggernaut X v10 | Standard X — full-step inference, maximum detail |
| Juggernaut XL Lightning | v9-base speed variant (5–7 steps) |
| Juggernaut Z | Lumina-Image-2 — cinematic, presentation-ready |
| Juggernaut Pro Flux | FLUX.1 — top-tier photo quality |
Two Versions: SAFE and Standard
Juggernaut X Hyper ships in two flavors:
- Juggernaut X Hyper (this repo) — the standard creative model.
- Juggernaut X Hyper SAFE — safety-tuned for workplace, education, and family-friendly contexts. Available exclusively on RunDiffusion via Fooocus.
