Meet SmolVLM: A Small Yet Powerful Vision-Language Model

SmolVLM is a cutting-edge 2B parameter vision-language model (VLM) designed to set new benchmarks in memory efficiency while maintaining strong performance.

Released under the Apache 2.0 license, SmolVLM is entirely open-source, offering full access to model checkpoints, datasets, and training tools.

Why SmolVLM?

The AI landscape is shifting from massive, resource-intensive models to more efficient, deployable solutions. SmolVLM bridges this gap by providing:

• Compact Design: Optimized for local setups, edge devices, and browsers.
• Low Memory Usage: Operates on minimal GPU resources.
• Strong Performance: Competes with larger models in multimodal tasks.

SmolVLM consists of three versions:

1. SmolVLM-Base: For downstream fine-tuning.
2. SmolVLM-Synthetic: Fine-tuned on synthetic datasets.
3. SmolVLM-Instruct: Pre-tuned for interactive, user-facing tasks.

Key Features

Architecture

• Replaces Llama 3.1 8B with SmolLM2 1.7B for a streamlined backbone.
• Introduces an aggressive pixel shuffle strategy, reducing visual data encoding size by 9x.
• Processes images at 384×384 resolution, optimized for memory efficiency.

Performance and Efficiency

• Achieves state-of-the-art memory efficiency, using as little as 5 GB GPU RAM during inference.
• Excels in benchmarks like DocVQA (81.6) and TextVQA (72.7), rivaling larger models.
• Boasts superior throughput—up to 16x faster generation speed compared to competitors.

Video Capabilities

With its extended context and image processing abilities, SmolVLM performs well in basic video analysis tasks, such as recognizing objects and describing actions in scenes.

Getting Started with SmolVLM

Easy Integration

You can load and interact with SmolVLM via Hugging Face’s Transformers library:
