# CrossEncoder based on answerdotai/ModernBERT-base

This is a [Cross Encoder](https://www.sbert.net/docs/cross_encoder/usage/usage.html) model finetuned from [answerdotai/ModernBERT-base](https://huggingface.co/answerdotai/ModernBERT-base) using the [sentence-transformers](https://www.SBERT.net) library. It computes scores for pairs of texts, which can be used for semantic textual similarity, semantic search, paraphrase mining, text classification, clustering, and more.

## Usage

### Direct Usage (Sentence Transformers)

First install the Sentence Transformers library:

```bash
pip install -U sentence-transformers
```

Then you can load this model and run inference.
```python
from sentence_transformers import CrossEncoder

# Download from the 🤗 Hub
model = CrossEncoder("tomaarsen/reranker-ModernBERT-base-nq-bce-static-retriever")
# Get scores for pairs of texts

The silver tips give the coat a shimmering appearance. Its eyes are almost always a dark and vivid green.

  | <code>who said my enemy's enemy is my friend</code>       | <code>The enemy of my enemy is my friend The enemy of my enemy is my friend is an ancient proverb which suggests that two opposing parties can or should work together against a common enemy. The earliest known expression of this concept is found in a Sanskrit treatise on statecraft, the Arthashastra, which dates to around the 4th century BC, while the first recorded use of the current English version came in 1884.[1][2]</code>                                                                                                                                                                                                                                                                                                                                                                         | <code>1</code> |

The 2018 NBA All-Star Game was played on February 18, 2018, at the Staples Center in Los Angeles, California. LeBron James of the Cleveland Cavaliers was named the All-Star Game Most Valuable Player.

Other descriptions for such courts include court of last resort, apex court, and highest (or final) court of appeal.

Supreme courts typically function primarily as appellate courts, hearing appeals from decisions of lower trial courts, or from intermediate-level appellate courts.[1]</code>                                                                                                                                                                                                                                                                                       | <code>1</code> |

  | <code>difference between russian blue and british blue cat</code> | <code>Russian Blue The coat is known as a "double coat", with the undercoat being soft, downy and equal in length to the guard hairs, which are an even blue with silver tips. However, the tail may have a few very dull, almost unnoticeable stripes. The coat is described as thick, plush and soft to the touch. The feeling is softer than the softest silk. The silver tips give the coat a shimmering appearance. Its eyes are almost always a dark and vivid green. Any white patches of fur or yellow eyes in adulthood are seen as flaws in show cats.[3] Russian Blues should not be confused with British Blues (which are not a distinct breed, but rather a British Shorthair with a blue coat as the British Shorthair breed itself comes in a wide variety of colors and patterns), nor the Chartreux or Korat which are two other naturally occurring breeds of blue cats, although they have similar traits.</code> | <code>1</code> |

  | <code>what year did the movie the sound of music come out</code>  | <code>The Sound of Music (film) The film was released on March 2, 1965 in the United States, initially as a limited roadshow theatrical release. Although critical response to the film was widely mixed, the film was a major commercial success, becoming the number one box office movie after four weeks, and the highest-grossing film of 1965. By November 1966, The Sound of Music had become the highest-grossing film of all-time—surpassing Gone with the Wind—and held that distinction for five years. The film was just as popular throughout the world, breaking previous box-office records in twenty-nine countries. Following an initial theatrical release that lasted four and a half years, and two successful re-releases, the film sold 283 million admissions worldwide and earned a total worldwide gross of $286,000,000.</code>                                                                             | <code>1</code> |
