# BioJev-Nano — System One API

The System One compatibility server is maintained in the main BioJev repository:

https://github.com/Gabriel382/BioJev

After cloning/installing BioJev, serve this local model directory with:

```bash
python scripts/serve_systemone.py \
  --checkpoint /path/to/BioJev-Nano \
  --model-name biojev-nano \
  --load-in-4bit \
  --host 0.0.0.0 \
  --port 8000
```

Endpoint:

```text
POST /v1/systemone
```

Supported decision types:

- `choice`
- `noul`
- `score`

BioJev-Nano remains a three-class NLI sequence classifier. The System One endpoint is
a compatibility bridge which converts each candidate into an NLI hypothesis and scores
it using the existing trained checkpoint.
