# The Smol Training Playbook

by [Hugging Face (SmolLM team)](https://huggingfacetb-smol-training-playbook.hf.space/)

[Read the original →](https://huggingfacetb-smol-training-playbook.hf.space/)

A training account that includes failed experiments and engineering decisions.

The SmolLM team explains how data mixtures, architecture choices and training operations interact in a complete model project. Its account of setbacks makes it useful for planning experiments rather than copying a final recipe without context.
