Hentai-NSFW-LoRA-v3

Hentai NSFW LoRA v3

Somehow, the convention is still open. 👋

Let's be honest: I know what many of you were hoping to see when you flipped through manga—and it was not the table of contents. Qwen Image 2512 can now turn that long-standing wish into pixels. Apparently dreams do come true; they just need a LoRA, a sufficiently shameless prompt, and 96GB of VRAM.

Some datasets choose one style and stay there. This one changed artists, decades, proportions, line weight, and rendering habits before breakfast. Training it felt less like teaching a single illustrator and more like trying to keep an entire convention moving in roughly the same direction.

Important Anatomy Limitation: The training dataset contains a very wide range of visual styles and anatomical conventions. Because the style changes so substantially from image to image, this LoRA does not guarantee anatomical accuracy. It may reproduce exaggerated proportions, inconsistent structures, or anatomy that follows a particular drawing style rather than physical reality. Consider this a documented limitation, not a surprise anatomy expansion pack.

Hentai NSFW LoRA v3 is an experimental anime and 2D illustration LoRA for Qwen/Qwen-Image-2512 Text-to-Image. It focuses on hentai illustration, clean line art, expressive anime rendering, and a broad range of adult NSFW compositions.

The objective is style coverage and prompt responsiveness across a diverse illustration dataset. This is not an anatomy-correction model, and it should not be evaluated as one.

Adult-content notice: This repository contains explicit adult material and is intended only for adults. All people described in the examples are adults.

🧪 Experimental Goal

The dataset intentionally spans many illustration styles instead of forcing a single narrow visual identity. The goal is to improve the base model's ability to respond to adult anime and hentai prompt structures while retaining useful variation in line work, coloring, proportions, and rendering.

That diversity comes with a trade-off. Results may vary significantly between prompts, seeds, compositions, and source styles. Anatomical consistency is not guaranteed, especially in difficult viewpoints, close framing, heavy occlusion, or highly exaggerated styles.

⚠️ Base Model Compatibility

This LoRA is intended for:

• Qwen/Qwen-Image-2512 for Text-to-Image generation

Compatibility with Qwen-Image-Edit or unrelated model architectures is not guaranteed. A different base checkpoint may produce weak effects, artifacts, incorrect colors, or a loading error.

---

🔍 Scope and Limitations

Possible limitations include:

• inconsistent body proportions between illustration styles
• inaccurate hands, fingers, feet, limbs, or joints
• local anatomy that follows stylized drawing conventions rather than reality
• exaggerated anatomy inherited from parts of the training dataset
• inconsistent line weight, shading, or coloring between seeds
• artifacts in difficult poses, close framing, or heavy occlusion
• occasional conflict between prompt composition and learned style

This model improves adult anime and hentai generation tendencies; it does not enforce anatomical correctness. Review generated output carefully and regenerate or edit visible defects when necessary.

📄 About Training Prompts

This repository includes a downloadable prompts.txt containing 500 adult-only testing prompts.

If prompt engineering is not on today's schedule, pick one, edit it, and let the seed make the remaining questionable decisions. If the result is excellent, naturally it was careful creative direction. If it is strange, the seed was clearly having a difficult afternoon.

🧩 Low-VRAM Inference (16–24 GB)

The following example quantizes the transformer and text encoder to 4-bit, enables CPU offloading, and uses VAE tiling. It is slower than the high-memory example but substantially reduces VRAM requirements.

Low-VRAM Installation

pip install -U diffusers transformers accelerate peft safetensors bitsandbytes

Low-VRAM Python

import torch
from diffusers import DiffusionPipeline
from diffusers.quantizers import PipelineQuantizationConfig


BASE_MODEL_ID = "Qwen/Qwen-Image-2512"
LORA_MODEL_ID = "perpetual3x/Hentai-NSFW-LoRA-v3"
LORA_WEIGHT_NAME = "hentaiv3.safetensors"

quant_config = PipelineQuantizationConfig(
    quant_backend="bitsandbytes_4bit",
    quant_kwargs={
        "load_in_4bit": True,
        "bnb_4bit_quant_type": "nf4",
        "bnb_4bit_compute_dtype": torch.bfloat16,
    },
    components_to_quantize=["transformer", "text_encoder"],
)

pipe = DiffusionPipeline.from_pretrained(
    BASE_MODEL_ID,
    torch_dtype=torch.bfloat16,
    quantization_config=quant_config,
)

pipe.load_lora_weights(
    LORA_MODEL_ID,
    weight_name=LORA_WEIGHT_NAME,
    adapter_name="hentai_v3",
)
pipe.set_adapters(["hentai_v3"], adapter_weights=[1.0])

pipe.enable_model_cpu_offload()
pipe.vae.enable_tiling()

prompt = (
    "The image is a Hentai, anime illustration, 2D illustration, "
    "clean line art, an adult woman, detailed anime artwork"
)
negative_prompt = (
    "child, minor, underage, low quality, blurry, distorted anatomy, "
    "malformed hands, extra limbs, duplicated body parts, watermark, text"
)

generator = torch.Generator(device="cuda").manual_seed(42)

image = pipe(
    prompt=prompt,
    negative_prompt=negative_prompt,
    width=768,
    height=1024,
    num_images_per_prompt=1,
    num_inference_steps=20,
    true_cfg_scale=3.0,
    max_sequence_length=256,
    generator=generator,
).images[0]

image.save("hentai_v3_low_vram.png")

If this still causes an out-of-memory error, replace pipe.enable_model_cpu_offload() with pipe.enable_sequential_cpu_offload(). Sequential CPU offloading uses less GPU memory but is substantially slower.
