nanoVLM is a lightweight toolkit for training Vision Language Models (VLMs) using pure PyTorch, inspired by nanoGPT. It uses SigLIP as vision backbone and SmolLM2 as language backbone, with a modality projection module. The entire codebase is minimal and readable, and training can be launched on a free Colab notebook.

## Evidence

Verbatim from https://huggingface.co/blog/nanovlm:

> nanoVLM is the simplest way to get started with training your very own Vision Language Model (VLM) using pure PyTorch.
