**CAT** is a minimal and lightweight Vision-Language Model (VLM) designed for efficient training and experimentation. Built using pure PyTorch, the entire model architecture and training logic fits within ~750 lines of code. It combines a ViT-based image encoder (SigLIP-B/16-224-85M) with a lightweight causal language model (SmolLM2-135M), resulting in a compact 222M parameter model.


**Usage:**

Follow the install instructions and run the following code:

```python
from models.vision_language_model import CAT

model = CAT.from_pretrained("mahwizzzz/CAT")
```
