In the rapidly advancing field of AI, Vision Language Models (VLMs) are gaining attention for their ability to understand and generate both images and text. For those looking to get hands-on with VLMs, nanoVLM offers a simple and efficient toolkit that makes training a VLM easy and accessible. Based on pure PyTorch, nanoVLM allows users to launch a Vision Language Model training session without needing complex setup or resources. This guide takes you through the core features of nanoVLM, its architecture, and how you can start building your own Vision Language Model with minimal effort.
Overview of nanoVLM
nanoVLM is a lightweight toolkit designed for building and training Vision Language Models (VLMs) using pure PyTorch. Inspired by Andrej Karpathy’s nanoGPT, it provides a similar framework but tailored for the vision domain. The key strength of nanoVLM lies in its simplicity — the codebase is kept minimal and readable, making it an ideal tool for beginners interested in understanding the fundamentals of VLMs without feeling overwhelmed.
VLMs are models that process both image and text data to generate textual outputs. The core application of these models ranges from image captioning to visual question answering (VQA). In the case of nanoVLM, the primary focus is on Visual Question Answering (VQA), a task where the model answers questions based on the content of images.
What is a Vision Language Model (VLM)?
A Vision Language Model (VLM) is a multi-modal AI model that takes both images and text as inputs and generates text as output. By understanding both the visual and textual information, a VLM can perform tasks like captioning images, detecting objects, segmenting images, or even answering questions related to visual content. The ability to generate text based on visual and textual inputs opens up many possibilities in the world of AI applications.
For example, nanoVLM can be used for:
Image captioning: Describing the content of an image in words.
Object detection: Identifying objects in an image and providing their locations.
Visual Question Answering (VQA): Answering questions related to the content of an image.
What Undercode Says:
nanoVLM is designed to be an easy entry point into the world of Vision Language Models. The lightweight toolkit provides a streamlined way to train and experiment with VLMs in PyTorch, and it is especially valuable for those just starting out in machine learning and computer vision.
The architecture of nanoVLM is based on two popular models: a Vision Transformer (ViT) for image processing and a Llama 3-based language model for text generation. By aligning these two modalities, nanoVLM allows you to train models that can process both text and images effectively. The training process itself is simplified through a set of pre-configured scripts, making it easy for users to get started.
The system is designed to be flexible, allowing users to swap out the vision and language backbones as needed. This makes nanoVLM an ideal platform for experimentation, as it provides a solid foundation while allowing room for customizations.
What Makes nanoVLM Stand Out?
1. Simplicity:
- Flexibility: You can train a VLM using different datasets and configurations, or swap out the pre-trained backbones for other models.
- Cost-Effectiveness: nanoVLM can be trained on a free Colab notebook, allowing anyone to get started with no additional hardware requirements.
In terms of usage, nanoVLM shines in how easy it makes running inference on pre-trained models or training your own from scratch. By leveraging Hugging Face’s infrastructure and allowing easy access to pre-trained models, nanoVLM simplifies the entire process of building and deploying a VLM.

1. Ease of Use:
- Performance: While nanoVLM doesn’t aim to outperform state-of-the-art models, it serves as an excellent educational tool and base for experimentation.
- Flexibility: The toolkit supports the use of various vision and language backbones, allowing users to customize their VLM based on project requirements.
Prediction: What’s Next for nanoVLM?
Looking ahead, nanoVLM could serve as a gateway to more advanced VLM research and applications. Given its minimalistic approach, it could become a staple for learning and building upon in the rapidly evolving field of Vision Language Models. Future developments could involve better model architectures, more efficient training algorithms, or expanded support for different tasks beyond Visual Question Answering.
Moreover, as AI continues to merge vision and language, nanoVLM’s straightforward design could evolve into a powerful tool for more complex real-world applications, such as interactive AI systems, autonomous vehicles, or advanced content creation tools. The potential for expansion and adaptation is enormous, and nanoVLM is positioned to lead the way for learners and developers exploring the multi-modal AI landscape.
