+
+**nanoVLM** 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.
+
+For more information, check out the base model on https://huggingface.co/lusxvr/nanoVLM-222M.
+
+**Usage:**
+
+Clone the nanoVLM repository: https://github.com/huggingface/nanoVLM.
+Follow the install instructions and run the following code:
+
+```python
+from models.vision_language_model import VisionLanguageModel
+
+model = VisionLanguageModel.from_pretrained("lusxvr/nanoVLM")
+```
