IR](https://experimaestro-ir.readthedocs.io/en/latest/)

```py from xpmir.models import AutoModel
from xpmir.models import AutoModel

# Model that can be re-used in experiments
model = AutoModel.load_from_hf_hub("xpmir/monobert")

# Use this if you want to actually use the model
model = AutoModel.load_from_hf_hub("xpmir/monobert", as_instance=True)
model.initialize()
model.rsv("walgreens store sales average", "The average Walgreens salary ranges...")
