vit-nsfw-stable-diffusion
This model is a fine-tuned version of vit-base-patch16-384 on ~1.7M generated images from the AdamCodd/Civitai-8m-prompts dataset, balanced between NSFW/SFW labels. It achieves the following results on the evaluation set:
- Loss: 0.1592
- Accuracy: 0.9349
Unlike AdamCodd/vit-base-nsfw-detector model, this one was exclusively trained on generated images from stable diffusion.

Model description
The Vision Transformer (ViT) is a transformer encoder model (BERT-like) pretrained on a large collection of images in a supervised fashion, namely ImageNet-21k, at a resolution of 224x224 pixels. Next, the model was fine-tuned on ImageNet (also referred to as ILSVRC2012), a dataset comprising 1 million images and 1,000 classes, at a higher resolution of 384x384.
Intended uses & limitations
Usage for a local image:
from transformers import pipeline
from PIL import Image
img = Image.open("<path_to_image_file>")
predict = pipeline('image-classification', model='AdamCodd/vit-nsfw-stable-diffusion')
predict(img)
Usage for a distant image:
from transformers import ViTImageProcessor, AutoModelForImageClassification
from PIL import Image
import requests
url = 'https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/ba55f276-5aa5-446f-c59a-8fff4d209100/width=512/ba55f276-5aa5-446f-c59a-8fff4d209100.jpeg'
image = Image.open(requests.get(url, stream=True).raw)
processor = ViTImageProcessor.from_pretrained('AdamCodd/vit-nsfw-stable-diffusion')
model = AutoModelForImageClassification.from_pretrained('AdamCodd/vit-nsfw-stable-diffusion')
inputs = processor(images=image, return_tensors="pt")
outputs = model(**inputs)
logits = outputs.logits
predicted_class_idx = logits.argmax(-1).item()
print("Predicted class:", model.config.id2label[predicted_class_idx])
# Predicted class: sfw
Usage with Transformers.js (Vanilla JS):
/* Instructions:
* - Place this script in an HTML file using the <script type="module"> tag.
* - Ensure the HTML file is served over a local or remote server (e.g., using Python's http.server, Node.js server, or similar).
* - Replace 'https://example.com/path/to/image.jpg' in the classifyImage function call with the URL of the image you want to classify.
*
* Example of how to include this script in HTML:
* <script type="module" src="path/to/this_script.js"></script>
*
* This setup ensures that the script can use imports and perform network requests without CORS issues.

image.onerror = reject;
image.src = URL.createObjectURL(blob);
});
const img = await imagePromise; // Ensure the image is loaded
const classificationResults = await classifier([img.src]); // Classify the image
console.log('Predicted class: ', classificationResults[0].label);
} catch (error) {
console.error('Error classifying image:', error);
}
}
// Example usage
classifyImage('https://example.com/path/to/image.jpg');
// Predicted class: sfw
Since this model has been trained on generated images from stable diffusion, it won't perform as well on real pictures (in that case just use my other ViT model).
It performs very well on generated images and would pair well with the following AdamCodd/distilroberta-nsfw-prompt-stable-diffusion model to filter both prompts and images, ensuring safe results.
