# MFFT — Multi-Frequency Fusion Transformer, Detection API

FastAPI inference server for AI-generated image detection. Three model
variants are served and selectable per request.

> **Demo checkpoints:** these are *pilot* models (1 training epoch on a 5K
> subset) published for pipeline demonstration. Full-scale weights will
> replace them after the training campaign completes.

## Endpoints

- `GET /` — health
- `GET /models` — available variants (`tiny` 372K, `base` 1.62M, `large` 6.30M)
- `POST /predict?model=base` — multipart `file=<image>`; returns prediction,
  probabilities, anomaly heatmap (base64 PNG), frequency band contributions
- `POST /predict/batch?model=large` — multiple files

## Example

```bash
curl -X POST "https://mohsineli-mfft-api.hf.space/predict?model=large" \
  -H "Authorization: Bearer free" \
  -F "file=@image.jpg"
```
