# add/remove files as needed
# Caching note: Unfortunately due to CDN caching the uploaded model may be unavailable for up to 24hs after upload
# So the only way to start using the new model sooner is either:
# 1. download it to a local path and use that path as model_name
# 2. make sure you use: from_pretrained(..., use_cdn=False) everywhere
