GLOSSARY
What is a model tree?
Model treeA model tree is a model’s lineage: the base model it was fine-tuned, quantized or converted from, that model’s own base, and so on — together with the fine-tunes built on it.
It is recorded through base_model in systemone.yaml. The registry links each step to its page and continues through Hugging Face when a base lives there, so a fine-tune of an MLX conversion of Laya shows all three — and the ModernBERT backbone above them.
