ayushexel/reranker-ModernBERT-base-gooaq-bce-495000

ModernBERT-base trained on GooAQ

This is a Cross Encoder model finetuned from answerdotai/ModernBERT-base using the sentence-transformers library. It computes scores for pairs of texts, which can be used for text reranking and semantic search.

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("ayushexel/reranker-ModernBERT-base-gooaq-bce-495000")
# Get scores for pairs of texts
pairs = [
    ['how much coffee is in a mocha frappe from starbucks?', 'The Mocha Frappuccino Light Blended Beverage has slightly more caffeine: Tall - 60 mg. Grande - 95 mg. Venti Iced - 120 mg.'],
    ['how much coffee is in a mocha frappe from starbucks?', "Typically Starbucks Vanilla Bean Frappuccino has no coffee in it at all. I believe it's made with sweetened condensed milk, vanilla bean powder and ice and topped with whipped cream of course! According to the Starbucks menu online their frappuccino has 57 grams of sugar and 59 grams of carbs in one 16 ounce serving!"],
    ['how much coffee is in a mocha frappe from starbucks?', 'It also has 5g of protein and 75mg of caffeine. The Mocha Cookie Crumble Frappucino pours a blend of coffee, milk and ice atop whipped cream and chocolate cookie crumble. The whole thing is topped with a blend of rich mocha sauce and Frappuccino chips.'],
    ['how much coffee is in a mocha frappe from starbucks?', 'There are 460 calories in 1 serving of Starbucks Java Chip Frappuccino Blended Coffee with Whipped Cream (Grande).'],
    ['how much coffee is in a mocha frappe from starbucks?', 'Each 14 fl. oz bottle contains 250 calories, 4.5 grams of fat, 38 grams of sugar, and 150 milligrams of caffeine. So, while certainly not the healthiest option, they are convenient for anyone who loves iced Starbucks lattes. The drink is inspired by the Salted Caramel Mocha served seasonally at Starbucks stores.'],
]
scores = model.predict(pairs)
