Special thanks to:

• Google for the Vision Transformer (ViT) architecture
• dima806 for fine-tuning on the CIFAKE dataset for AI image detection

Model Description

• Architecture: ViT-Base (86M parameters)
• Input Size: 224x224 pixels
• Training Data: CIFAKE dataset (AI-generated vs real images)
• Task: Binary classification (Real vs Fake/AI-generated)

Usage

from transformers import pipeline

detector = pipeline("image-classification", model="capcheck/ai-image-detection")
result = detector("path/to/image.jpg")

# Output:
# [{"label": "Fake", "score": 0.95}, {"label": "Real", "score": 0.05}]

Labels

Label	Description
Real	Authentic photograph or real-world image
Fake	AI-generated or synthetically created image

Performance

This model was trained on the CIFAKE dataset. Performance on modern AI generators (Flux, Midjourney v6, DALL-E 3, Stable Diffusion 3) may vary.

See dima806's model card for detailed training metrics.

Limitations

• Trained primarily on older AI generators (pre-2024)
• May have reduced accuracy on:
  • Very new AI generators not in training data
  • Heavily compressed images (low JPEG quality)
  • Images smaller than 224x224 pixels
• Works best on images with clear subjects

Intended Use

• Content moderation and authenticity verification
• Research into AI-generated content detection
• Educational purposes

Not intended for:

• Making consequential decisions without human review
• Law enforcement evidence without corroborating sources

Ethical Considerations

• This tool is not 100% accurate - false positives harm legitimate creators
• False negatives can allow misinformation to spread
• Use in conjunction with other verification methods
• Human review is recommended for high-stakes decisions

Roadmap

Current Version (v1.0.0)

Base model from dima806's CIFAKE-trained ViT. Solid foundation for AI detection.

Planned Improvements

Phase 1: Modern Generator Training

• Fine-tune on images from Flux, Midjourney v6, DALL-E 3, Stable Diffusion 3
• Target: Reduce false negatives on 2024+ AI generators

Phase 2: False Positive Reduction

• Curate dataset of real images commonly flagged as AI
• Photography edge cases: HDR, heavy editing, digital art
• Target: <5% false positive rate

Phase 3: Continuous Updates

• Quarterly re-training as new generators emerge
• Community feedback integration
• Benchmark against latest AI generators

Contributing

We welcome:

• Dataset contributions (properly licensed images)
• Bug reports and false positive/negative examples
• Benchmark results on new generators
