Usage

Direct Usage (Sentence Transformers)

First install the Sentence Transformers library:

pip install -U sentence-transformers

Then you can load this model and run inference.

from sentence_transformers import CrossEncoder

# Download from the 🤗 Hub
model = CrossEncoder("tomaarsen/reranker-ModernBERT-base-gooaq-bce-0margin-3min-100max-5top")
# Get scores for pairs of texts
pairs = [
    ['what is baking powder bicarbonate soda?', 'Baking soda and bicarbonate of soda are actually different names for the same thing. ... Both bicarbonate of soda and baking powder are leavening (raising) agents. When included in a batter, the leavening agent creates air bubbles that expand when cooked, and cause it to rise.'],
    ['what is baking powder bicarbonate soda?', "What is baking soda? Baking soda is a leavening agent used in baked goods like cakes, muffins, and cookies. Formally known as sodium bicarbonate, it's a white crystalline powder that is naturally alkaline, or basic (1).

    ['what is baking powder bicarbonate soda?', 'The chemical name for baking powder is sodium hydrogencarbonate. You may see it called bicarbonate of soda in the supermarket. This is the old name for the same stuff. It has the chemical formula NaHCO3.'],
    ['what is baking powder bicarbonate soda?', "Substituting baking soda for baking powder What's more, baking soda has much stronger leavening power than baking powder. As a rule of thumb, about 1 teaspoon of baking powder is equivalent to 1/4 teaspoon of baking soda."],

]
scores = model.predict(pairs)
print(scores.shape)
