Juggernaut XL v8 is the final release in the RunDiffusion Photo v1 generation of the Juggernaut SDXL line — the version directly before the v9 jump to Photo v2. Useful if you have workflows or LoRAs tuned against the v8 aesthetic, or want the predecessor's slightly softer photographic feel.
When to use v8
- 🔬 You have LoRAs or pipelines validated against v8 and want exact consistency.
- 🎨 You prefer v8's slightly softer contrast and lighting profile vs. v9's punchier output.
- 📚 You're auditing the Juggernaut release line for research or comparison.
For new projects, start with the latest Juggernaut models instead.

Two Ways to Run Juggernaut XL v8
🚀 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 — Diffusers
import torch
from diffusers import DiffusionPipeline
pipe = DiffusionPipeline.from_pretrained(
"RunDiffusion/Juggernaut-XL-v8",
torch_dtype=torch.float16,
use_safetensors=True,
).to("cuda")
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=832, height=1216, num_inference_steps=35, guidance_scale=5.0).images[0]
image.save("juggernaut_xl_v8.png")
For ComfyUI / Forge / InvokeAI / SwarmUI: download the single-file checkpoint and drop it into your models/checkpoints/ directory.
