Welcome to Smol Models, a family of efficient and lightweight AI models from Hugging Face. Our mission is to create fully open powerful yet compact models, for text and vision, that can run effectively on-device while maintaining strong performance.
Our 3B model outperforms Llama 3.2 3B and Qwen2.5 3B while staying competitive with larger 4B alternatives (Qwen3 & Gemma3). Beyond the performance numbers, we're sharing exactly how we built it using public datasets and training frameworks.
Ressources:
Summary:
- 3B model trained on 11T tokens, SoTA at the 3B scale and competitive with 4B models
- Fully open model, open weights + full training details including public data mixture and training configs
- Instruct model with dual mode reasoning, supporting think/no_think modes
- Multilingual support for 6 languages: English, French, Spanish, German, Italian, and Portuguese
- Long context up to 128k with NoPE and using YaRN
SmolVLM is our compact multimodal model that can:
- Process both images and text and perform tasks like visual QA, image description, and visual storytelling
- Handle multiple images in a single conversation
- Run efficiently on-device
