Key point

Hugging Face has released nanoVLM, a lightweight toolkit that lets even beginners easily train Vision Language Models.

Details

nanoVLM is a minimal PyTorch-based toolkit for training Vision Language Models (VLM), created inspired by Andrej Karpathy's nanoGPT.

The codebase is intentionally designed to be simple and readable, making it optimized for beginners or researchers who want to understand the inner workings of VLMs.

Key Features and Architecture:

  • Vision Backbone: Uses Google's SigLIP vision encoder
  • Language Backbone: Based on the Llama 3 architecture
  • Alignment: Aligns visual and language modalities through a Modality Projection module
  • Training Objective: Focused on Visual Question Answering (VQA)

Users can start training immediately via Google Colab without any separate local setup.
