SmolLM
Hugging Face's fully open small-model family, released with open data and training recipes.
SmolLM is Hugging Face's family of small language models, and they are "fully open" in a strong sense: the training data, code, and recipes are published alongside the weights.
That transparency makes SmolLM valuable for teams that need to know exactly what went into a model, not just download it.
Where it fits
A fit when small size plus full transparency (open data and training recipe) matters for trust or research.
Where it does not fit
Small models by design: not built to compete with large models on raw capability.
