# ettin-reranker-1b-v1
This is a [Cross Encoder](https://www.sbert.net/docs/cross_encoder/usage/usage.html) model finetuned from [jhu-clsp/ettin-encoder-1b](https://huggingface.co/jhu-clsp/ettin-encoder-1b) on the [cross-encoder/ettin-reranker-v1-data](https://huggingface.co/datasets/cross-encoder/ettin-reranker-v1-data) dataset 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.
See the [release blogpost](https://huggingface.co/blog/ettin-reranker) for details on the training recipe, evaluation results, and speed benchmarks against other public rerankers. The [Evaluation](#evaluation) section below also has the headline numbers.

## 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(
"cross-encoder/ettin-reranker-1b-v1",
model_kwargs={"dtype": "bfloat16", "attn_implementation": "flash_attention_2"}, # Optional: pip install kernels
)
# Get scores for pairs of inputs
query = "Which planet is known as the Red Planet?"
passages = [
"Venus is often called Earth's twin because of its similar size and proximity.",
"Mars, known for its reddish appearance, is often referred to as the Red Planet.",
"Jupiter, the largest planet in our solar system, has a prominent red spot.",
"Saturn, famous for its rings, is sometimes mistaken for the Red Planet.",
]
scores = model.predict([(query, passage) for passage in passages])
print(scores)
# [ 2.984375 11.9375 5.71875 9.625 ]
# Or rank passages by relevance to a single query
ranked = model.rank(query, passages)
print(ranked)
# [{'corpus_id': 1, 'score': np.float32(11.9375)}, ...]
```

## Evaluation
### MTEB(eng, v2) Retrieval
Each model in the ettin-reranker-v1 family was evaluated on the full [`MTEB(eng, v2)` Retrieval benchmark](https://github.com/embeddings-benchmark/mteb) (10 tasks, top-100 reranked) using MTEB's [two-stage reranking flow](https://embeddings-benchmark.github.io/mteb/get_started/advanced_usage/two_stage_reranking/), pairing each reranker with six embedding models that span the speed/quality spectrum.
The dashed retriever-only line in each chart below is the headline number to beat. Anything below it means the reranker actively hurts the pipeline on average:

### Speed
All six released models were benchmarked against thirteen public rerankers on three hardware tiers, using [`sentence-transformers/natural-questions`](https://huggingface.co/datasets/sentence-transformers/natural-questions) at `max_length=512` with each model's best supported attention implementation. The full sweep over `fp32+SDPA`, `bf16+SDPA`, padded `bf16+FA2`, and unpadded `bf16+FA2` (showing why the ettin-reranker-v1 family is faster than other ModernBERT-based rerankers) is in the [release blogpost](https://huggingface.co/blog/ettin-reranker#speed). This table shows the throughput in pairs per second on a NVIDIA H100 80GB, all in `bfloat16`:
