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("kwondw/reranker-ModernBERT-base-gooaq-bce")
# Get scores for pairs of inputs
pairs = [
    ['what to spend my nectar points on?', "There are lots of different places and ways you can spend your points. You can spend straight from your card by swiping it at Sainsbury's, Vue Cinemas and Argos or you can spend them online at nectar.com on great things like holidays, hotels and days out."],
    ['what to spend my nectar points on?', "If you have already registered for Online Services, just log in to see your points balance. For detailed points transactions, go to Membership Rewards page and click on 'Your points Account' and then 'My Points' at the top of the page."],

    ['what to spend my nectar points on?', 'To redeem your Amex Blue Sky points, log in to your account via the Amex travel portal. At the checkout, there will be an option to pay with points. Points are worth 1 cent each toward flights and 0.7 cents each toward other travel costs.'],
    ['what to spend my nectar points on?', 'Yes, TD rewards points are worth $0.005 each, and must be redeemed in increments of 10,000, at a value of $50 per 10,000 points.'],
]
scores = model.predict(pairs)
print(scores)
