✨ What is Z-Anime?

Z-Anime is a full fine-tune of Alibaba's Z-Image Base architecture — not a LoRA merge, but a fully trained anime-focused model family built from the ground up.

Built on the S3-DiT (Single-Stream Diffusion Transformer, 6B parameters), Z-Anime inherits the strong foundation of Z-Image Base: rich diversity, strong controllability, full negative prompt support, and a high ceiling for fine-tuning — now adapted for anime-style generation.

This repository contains the full Z-Anime family:

🟣 AIO

All-in-one checkpoints with image model + Text Encoder + VAE integrated into a single file for the easiest setup. Available for Base, Distill-4-Step and Distill-8-Step.

🎌 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

yaml

steps: 28-50
cfg: 3.0-5.0   # up to 9.0 possible
sampler: euler_ancestral
scheduler: beta
negative_prompt: strongly recommended

CFG Guide

3.0–5.0 → sweet spot for balanced quality and creativity
5.0–7.0 → tighter prompt adherence
7.0–9.0 → maximum control, but watch for oversaturation
Above 9.0 → not recommended

Negative prompts have full effect on Z-Anime Base and are highly recommended.

⚡ Z-Anime Distill-8-Step

The sweet spot of the family.

Distilled from Z-Anime Base, this version delivers strong anime results in just 8 steps while keeping most of the quality.

Recommended Settings

yaml

steps: 8
cfg: 1.0   # max ~1.5
sampler: euler_ancestral
scheduler: beta
negative_prompt: limited effect

CFG Guide

Best at CFG 1.0
Small increases to 1.3–1.5 are possible
Do not go above 1.5 — artifacts may appear

Negative prompts have only limited effect at this distillation level. If your workflow includes ConditioningZeroOut, prefer that instead of a large negative prompt.

🚀 Z-Anime Distill-4-Step

The fastest Z-Anime variant.

Built for maximum throughput — ideal for rapid prototyping, quick batch generation, and speed-focused workflows.

Recommended Settings

yaml

steps: 4
cfg: 1.0   # max ~1.5
sampler: euler_ancestral
scheduler: beta
negative_prompt: limited effect

Tips for 4-Step

Stay at CFG 1.0 for the most stable results
Put the most important visual details early in the prompt
An optional upscaler such as hires fix or SeedVR2 can help recover fine detail

📐 Resolution Guide

Use Case	Resolution
Portrait / character art	832 × 1216
Landscape / scenes / backgrounds	1216 × 832
Square / general purpose	1024 × 1024
Tall / full body / wallpaper	768 × 1344
Cinematic / wide scenes	1920 × 1088
Detailed portraits	1024 × 1536

Supported range: approximately 512 × 512 to 2048 × 2048, any aspect ratio.

💡 Prompting Guide

Natural language works best — not tag lists.

✅ Good

A young anime girl with long silver hair and golden eyes, wearing a traditional shrine maiden outfit with white haori and red hakama. She stands in a sunlit bamboo forest, cherry blossoms falling softly around her. Warm afternoon light filtering through the trees, detailed fabric shading, expressive face, calm serene expression, high quality anime illustration with fine line work.

❌ Avoid

anime girl, silver hair, shrine maiden, bamboo, cherry blossom, warm light

Character Portraits

Detailed anime portrait of [character], soft rim lighting, expressive eyes with detailed reflections, fine hair strands, clean linework, professional anime illustration quality.

Action Scenes

Dynamic anime [scene], dramatic angle, motion energy, speed lines, particle effects, cinematic composition, detailed shading, high quality anime art.

Backgrounds & Landscapes

Anime [location] at [time of day], [lighting], [atmosphere], beautiful background art, wallpaper quality, highly detailed environment.

🔧 Installation

Step 1 — Download the version you want

Choose between:

Standard / Distill models in BF16 or FP8 (+ VAE + Text Encoder)
GGUF variants for low VRAM / CPU / AMD-friendly inference (+ VAE + Text Encoder)
AIO variants for single-file convenience (no extra VAE / Text Encoder needed)

Step 2 — Place the files

Standard BF16 / FP8 models

text

ComfyUI/models/diffusion_models/
├── z-anime-base-bf16.safetensors
├── z-anime-base-fp8.safetensors
├── 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

text

ComfyUI/models/unet/
├── z-anime-base-q8_0.gguf
└── z-anime-base-q4_k_s.gguf

Text Encoder

Two text encoders are included — pick one:

text

ComfyUI/models/clip/
└── qwen_3_4b-bf16.safetensors          # default (Z-Image standard, BF16)
   or
└── qwen_3_4b-fp8.safetensors           # default (Z-Image standard, FP8)
   or
└── qwen_3_4b-engineer-v4-bf16.safetensors   # alternative (Engineer V4, BF16)
   or
└── qwen_3_4b-engineer-v4-fp8.safetensors    # alternative (Engineer V4, FP8)

Default (qwen_3_4b-*) — the standard Z-Image text encoder, repackaged as a single .safetensors file (BF16 + FP8). This is what the model was trained against.
Engineer V4 (qwen_3_4b-engineer-v4-*) — an alternative full fine-tune of the Z-Image text encoder by BennyDaBall, drop-in compatible. Often produces more varied outputs from the same seed. See Credits below for the original repo.

VAE

text

ComfyUI/models/vae/
└── ae.safetensors

AIO variants

For the AIO versions, you only need the single checkpoint file — no extra VAE or Text Encoder required:

text

ComfyUI/models/checkpoints/
├── z-anime-base-aio-bf16.safetensors
├── z-anime-base-aio-fp8.safetensors
├── z-anime-distill-8step-aio-bf16.safetensors
├── z-anime-distill-8step-aio-fp8.safetensors
├── z-anime-distill-4step-aio-bf16.safetensors
└── z-anime-distill-4step-aio-fp8.safetensors

Step 3 — Load in ComfyUI

For standard BF16 / FP8 versions

Use:

Load Diffusion Model for the model file
CLIP Loader for the text encoder
VAE Loader for the VAE

For GGUF versions

Load the GGUF model from the models/unet/ folder
Use the same CLIP and VAE files as above

For AIO versions

Use a standard Checkpoint Loader — no extra CLIP or VAE loading required.

📦 Custom Nodes

rgthree-comfy
ComfyUI-Lora-Manager
ComfyUI-GGUF (only for the GGUF variants)
ComfyUI-SeedVR2_VideoUpscaler (optional, only for SeedVR2 upscale)

🐍 Using the Diffusers Folder

For Python users, the full Diffusers-format folder is included under diffusers/ and can be loaded directly with the subfolder argument:

python

import torch
from diffusers import ZImagePipeline

pipe = ZImagePipeline.from_pretrained(
    "SeeSee21/Z-Anime",
    subfolder="diffusers",
    torch_dtype=torch.bfloat16,
).to("cuda")

image = pipe(
    prompt="A young anime girl with long silver hair and golden eyes, "
           "shrine maiden outfit, sunlit bamboo forest, cherry blossoms, "
           "professional anime illustration, fine line work.",
    num_inference_steps=40,
    guidance_scale=4.0,
).images[0]

image.save("z-anime-output.png")

This format is also a clean starting point for further fine-tuning (LoRA or full fine-tune) with frameworks like OneTrainer, diffusers, or kohya-ss.

🧩 Official Workflow

A ready-to-use ComfyUI workflow that supports all variants (Base / Distill-8 / Distill-4, BF16 / FP8 / GGUF / AIO) is included in workflows/Z-Anime-Workflow-v1.json.

It includes:

📦 Model switch (Diffusion / GGUF / AIO loaders — toggle one at a time)
📖 Optional LoRA loader
✍️ Positive + Negative prompt nodes (with default anime negative)
📐 Resolution presets
🎨 Generate + 🔼 Optional 1.5× upscale with side-by-side compare
📚 Built-in MarkdownNote guide with settings per variant
