# FAST DROID Expert

A [FAST tokenizer](https://www.pi.website/research/fast), trained on the [DROID dataset](https://droid-dataset.github.io/) only. For a *universal* FAST tokenizer, applicable to any robot dataset, see [here](https://huggingface.co./physical-intelligence/fast).

For details about FAST tokenizers, see our paper on efficient action tokenization for VLA training:
