# ModernBERT-base trained on GooAQ
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 text reranking and semantic search.
## Model Details
### Model Description
- **Model Type:** Cross Encoder
- **Base model:** [answerdotai/ModernBERT-base](https://huggingface.co/answerdotai/ModernBERT-base)
- **Maximum Sequence Length:** 8192 tokens
- **Number of Output Labels:** 1 label
- **Language:** en
- **License:** apache-2.0
### Model Sources
- **Documentation:** [Sentence Transformers Documentation](https://sbert.net)
- **Documentation:** [Cross Encoder Documentation](https://www.sbert.net/docs/cross_encoder/usage/usage.html)
- **Repository:** [Sentence Transformers on GitHub](https://github.com/UKPLab/sentence-transformers)
- **Hugging Face:** [Cross Encoders on Hugging Face](https://huggingface.co/models?library=sentence-transformers&other=cross-encoder)
## 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-gooaq-bce-random")
# Get scores for pairs of texts
pairs = [
['is esurance a reputable company?', "Esurance auto insurance earned 4.5 stars out of 5 for overall performance. ... Based on these ratings, Esurance is among NerdWallet's Best Car Insurance Companies for 2020. Esurance offers all the usual coverage options, plus optional coverage including: Emergency roadside assistance."],
['is esurance a reputable company?', 'Coinsurance in property insurance is a means for insurers to obtain rate and premium equality. ... Rates are applied against a specified percentage (100, 90, or 80 percent, for example) of the value to the insured: building, contents, or business income.'],
['is esurance a reputable company?', 'Some employers offer both term life insurance coverage and supplemental life insurance. Term life insurance through your employer generally works like regular term life insurance. ... Supplemental life insurance is similar to a group term life insurance policy, but is typically more limited.'],
['is esurance a reputable company?', "Third party insurance is the legal minimum. This means you're covered if you have an accident causing damage or injury to any other person, vehicle, animal or property. It does not cover any other costs like repair to your own vehicle. You may want to use an insurance broker."],
['is esurance a reputable company?', 'In the United States, corporations have limited liability and the expression corporation is preferred to limited company. A "limited liability company" (LLC) is a different entity. However, some states permit corporations to have the designation Ltd. (instead of the usual Inc.) to signify their corporate status.'],
]
scores = model.predict(pairs)
print(scores.shape)
# (5,)
# Or rank different texts based on similarity to a single text
ranks = model.rank(
