 ## FLAN LLM
 This example is based on using [Google's Fine-tuned LAnguage Net (FLAN) models hosted on HuggingFace](https://huggingface.co/docs/transformers/model_doc/flan-t5).
 The larger the model, the longer it will take to fine-tune, and the more memory you'll need for it. The code
-here by default (which you can easily change) is set up to run on docker using the smallest FLAN model.
