🎌 Z-Anime | Full Anime Fine-Tune on Z-Image Base
Full Fine-Tune • Rich Aesthetics • Strong Diversity • Full Negative Prompt Support

✨ What is Z-Anime?
Z-Anime is a full fine-tune of Alibaba's Z-Image (Base) architecture — not a LoRA merge, but a completely retrained model optimized for anime aesthetics from the ground up.
Built on the S3-DiT (Single-Stream Diffusion Transformer) with 6 billion parameters, Z-Anime inherits everything that makes Z-Image Base special: rich diversity, strong controllability, full negative prompt support and a high ceiling for fine-tuning — now fully tuned for anime.
This page contains all three variants:
🎌 Z-Anime Base — Full quality, full control, full creativity ⚡ Z-Anime Distill-8-Step — Great results in 8 steps 🚀 Z-Anime Distill-4-Step — Maximum speed, 4 steps
Each variant is available in BF16 (~12GB) and FP8 (~6GB).

📦 Versions Overview
🟢 BF16 (~12GB)
Maximum precision. BFloat16 format, no quality compromise. Best for professional or commercial work and LoRA training. Still runs on 8GB VRAM.
🟡 FP8 (~6GB)
Recommended for most users. Half the file size, much faster downloads. Excellent quality, barely distinguishable from BF16. Perfect for everyday use and testing.
🎌 Z-Anime Base
The foundation of the Z-Anime family. A full fine-tune with the highest quality ceiling, the widest creative range and full negative prompt support.
Recommended Settings:
Steps: 28–50
CFG: 3.0–5.0 (up to 9.0 possible)
Sampler: euler_ancestral
Scheduler: beta
Negative: strongly recommended — very responsive!
CFG Guide: 3.0–5.0 is the sweet spot for balanced quality and creativity. 5.0–7.0 gives tighter prompt adherence. 7.0–9.0 is for maximum control — watch for over-saturation. Above 9.0 is not recommended.
Negative prompts have full effect on Z-Anime Base. The official workflow ships with an optimized negative prompt ready to use.
⚡ Z-Anime Distill-8-Step
The sweet spot of the family. Distilled from Z-Anime Base, delivering strong anime results in just 8 steps. Much faster than Base while keeping most of the quality intact.
Recommended Settings:
Steps: 8
CFG: 1.0 (max ~1.5)
Sampler: euler_ancestral
Scheduler: beta
Negative: limited effect
CFG Guide: Runs best at CFG 1.0 by design. Small nudges up to 1.3–1.5 are possible for slightly tighter prompt adherence. Do not go above 1.5 — artifacts may appear.
Negative prompts have limited effect at this distillation level. Use ConditioningZeroOut (included in the workflow) instead of writing a full negative prompt.
🚀 Z-Anime Distill-4-Step
The fastest Z-Anime variant. Built for maximum throughput — rapid prototyping, batch generation and situations where speed matters most.
Recommended Settings:
Steps: 4
CFG: 1.0 (max ~1.5)
Sampler: euler_ancestral
Scheduler: beta
Negative: limited effect
CFG Guide: At 4 steps the model has very little correction room. Stay at CFG 1.0 for the most stable results. Nudging up to 1.3–1.5 is possible but increases instability. Do not go above 1.5.
Tips for 4-Step: Be specific and front-load the most important details early in your prompt. The optional upscaler (hires fix or SeedVR2) in the workflow is especially useful here to recover fine detail.

🔧 Installation
Step 1 — Download your version (BF16 or FP8) for the variant you want.
Step 2 — Place the files:
ComfyUI/models/diffusion_models/
└── z-anime-base-bf16.safetensors (Base BF16)
└── z-anime-base-fp8.safetensors (Base FP8)
└── z-anime-distill-8step-bf16.safetensors
└── z-anime-distill-8step-fp8.safetensors
└── z-anime-distill-4step-bf16.safetensors
└── z-anime-distill-4step-fp8.safetensors
**GGUF variants**
ComfyUI/models/unet/
└── z-anime-q8_0.gguf
└── z-anime-q4_k_s.gguf
ComfyUI/models/clip/
└── qwen_3_4b.safetensors
ComfyUI/models/vae/
└── ae.safetensors
Step 3 — Load in ComfyUI:
Use the Load Diffusion Model node for the model file, a CLIPLoader node for the text encoder and a VAELoader node for the VAE.
Or use the official Z-Anime ComfyUI Workflow — it handles all three variants and both precisions with a built-in model switch.
For the GGUF versions:
- Load the **GGUF model from the models/unet/ folder**
- Use the same **CLIP** and **VAE** files as above
📦 Custom Nodes (for the official workflow)
ComfyUI-SeedVR2_VideoUpscaler (optional, only for SeedVR2 upscale)
