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's ideally used

A fit when small size plus full transparency — open data and training recipe — matters for trust or research.

Where it doesn't fit

Small models by design — not built to compete with large models on raw capability.
