FLUX Detector - Vision Transformer

Model Description

This model is a specialized binary classifier trained to detect images generated by FLUX.1-dev (Black Forest Labs). It achieves 99.85% accuracy with ZERO false positives on held-out test data.

Key Features

• 🎯 Specialist Detector: Optimized specifically for FLUX.1-dev images
• 🚀 Exceptional Accuracy: 99.85% test accuracy
• 🛡️ Zero False Positives: Never misclassifies real images as fake
• ⚡ Fast Inference: ~10ms per image on GPU
• 📊 Well-Validated: Separate train/val/test splits with no overlap

Performance

Test Accuracy:  0.9985
Precision:      1.0000 (PERFECT!)
Recall:         0.9970
F1 Score:       0.9985
AUC-ROC:        1.0000 (PERFECT!)

False Positive Rate: 0.0000 (0.0%!)
False Negative Rate: 0.0030

Quick Start

import torch
from PIL import Image
from transformers import ViTForImageClassification, ViTImageProcessor

# Load model and processor
model = ViTForImageClassification.from_pretrained(
    "ash12321/flux-detector-vit"
)
processor = ViTImageProcessor.from_pretrained(
    "google/vit-base-patch16-224"
)

# Load image
image = Image.open("test.jpg")
inputs = processor(images=image, return_tensors="pt")

# Get prediction
model.eval()
with torch.no_grad():
    outputs = model(**inputs)
    probs = torch.softmax(outputs.logits, dim=1)
    
    if probs[0][1] > 0.5:
        print(f"FLUX-Generated ({probs[0][1]:.2%} confident)")
    else:
        print(f"Real Image ({probs[0][0]:.2%} confident)")

Using the model.py Helper

from model import detect_image

result = detect_image("test.jpg", model_path="ash12321/flux-detector-vit")
print(f"Is Fake: {result['is_fake']}")
print(f"Confidence: {result['confidence']:.2%}")
