baseten-admin / reranker-ModernBERT-base-gooaq-bce

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("baseten-admin/reranker-ModernBERT-base-gooaq-bce")
# Get scores for pairs of texts
pairs = [
    ['how to put your phone on do not disturb on iphone?', 'Go to Settings > Do Not Disturb to turn on Do Not Disturb manually or set a schedule. to turn it on or off.'],
    ['how to put your phone on do not disturb on iphone?', "This icon means that your iPhone's Do Not Disturb feature is enabled."],
    ['how to put your phone on do not disturb on iphone?', 'About Do Not Disturb The Do Not Disturb option on the iPhone stops notifications, alerts and calls from making any noise, vibration or lighting up the phone screen when the screen is locked.'],
    ['how to put your phone on do not disturb on iphone?', 'Go to Settings > Do Not Disturb to turn on Do Not Disturb manually or set a schedule. to turn it on or off. If you set an alarm in the Clock app, the alarm goes off even when Do Not Disturb is on. Learn how to set and manage your alarms.'],
    ['how to put your phone on do not disturb on iphone?', "You can use the Do Not Disturb feature on your iPhone whenever you want to block any calls, texts, or other notifications from making your phone ring. The notifications and alerts will still be stored on your phone, and you can check them at any time, but your iPhone won't light up or ring."],
]
scores = model.predict(pairs)
print(scores.shape)
# (5,)

# Or rank different texts based on similarity to a single text
ranks = model.rank(
    'how to put your phone on do not disturb on iphone?',
    [
        'Go to Settings > Do Not Disturb to turn on Do Not Disturb manually or set a schedule. to turn it on or off.',
        "This icon means that your iPhone's Do Not Disturb feature is enabled.",
        'About Do Not Disturb The Do Not Disturb option on the iPhone stops notifications, alerts and calls from making any noise, vibration or lighting up the phone screen when the screen is locked.',
