# FALCON

Functional Assembly and Language for Compositional Reasoning in X-ray.

[Paper](https://arxiv.org/abs/2606.25701) ·
[Project page](https://yonathan-kiflom.github.io/FALCON/page/) ·
[Code](https://github.com/yonathan-kiflom/FALCON)

This repository contains the completed Stage-3 model, including Vicuna-7B-v1.5,
DINOv2-L/14, the trained RF-DETR segmentation detector, multimodal adapters,
and unmerged LoRA weights.

## Usage

Install the pinned dependencies from the code repository:

```bash
pip install 'falcon-x[train] @ git+https://github.com/yonathan-kiflom/FALCON.git'
```

Use `JonathanJMK/FALCON` or a local downloaded model directory. Authenticate
with `huggingface-cli login` when accessing the private repository. Review the
custom code before trusting it; pin a Hub commit with `revision=` for reproducible use.

```python
from transformers import AutoModel

model = AutoModel.from_pretrained(
    "JonathanJMK/FALCON", trust_remote_code=True,
).to("cuda").eval()

result, masks = model.predict(
    image="image.png", prompt="Describe the image.", max_new_tokens=256,
)
print(result["answer"])
```

Use `predict_segmentation` for grounding prompts and `predict_panoptic` for
panoptic prompts. Tokenization, image preprocessing, and prompt formatting are
included. The model supports one device; automatic multi-device dispatch and
quantized loading are not supported. The saved per-component precision is
preserved; do not cast the entire model to half precision.

Evaluate using the same model:

```bash
python -m falcon evaluate run --model JonathanJMK/FALCON \
  --dataset /path/to/falcon-x --split test --tasks all \
  --run-dir runs/falcon-evaluation --device cuda
```

## Scope and limitations

Trained on falcon-x for X-ray descriptions, questions, component
presence/completeness, instance grounding, and segmentation. Generated answers
and masks can be wrong; this is a research model, not a certified screening
system. Available structured heads are declared in `config.json`; untrained
risk and physical-link heads are not presented as predictions. Counterfactual
completeness does not establish real-world danger or physical connectivity.

The package preserves the trained architecture and LoRA for further research.
It is not an optimizer-state checkpoint, and loading with Transformers alone
does not make the repository's stage-training CLI a general fine-tuning tool.
Task metrics and evaluation limitations are documented in the code repository.
