# jina-reranker-v1-tiny-en |
|
|
|
This model is designed for **blazing-fast** reranking while maintaining **competitive performance**. What's more, it leverages the power of our [JinaBERT](https://arxiv.org/abs/2310.19923) model as its foundation. `JinaBERT` itself is a unique variant of the BERT architecture that supports the symmetric bidirectional variant of [ALiBi](https://arxiv.org/abs/2108.12409). This allows `jina-reranker-v1-tiny-en` to process significantly longer sequences of text compared to other reranking models, up to an impressive **8,192** tokens. |
|
|
|
To achieve the remarkable speed, the `jina-reranker-v1-tiny-en` employ a technique called knowledge distillation. Here, a complex, but slower, model (like our original [jina-reranker-v1-base-en](https://jina.ai/reranker/)) acts as a teacher, condensing its knowledge into a smaller, faster student model. This student retains most of the teacher's knowledge, allowing it to deliver similar accuracy in a fraction of the time. |
|
|
|
Here's a breakdown of the reranker models we provide: |
|
|
|
| Model Name | Layers | Hidden Size | Parameters (Millions) | |
|
| ------------------------------------------------------------------------------------ | ------ | ----------- | --------------------- | |
|
| [jina-reranker-v1-base-en](https://jina.ai/reranker/) | 12 | 768 | 137.0 | |
|
| [jina-reranker-v1-turbo-en](https://huggingface.co/jinaai/jina-reranker-v1-turbo-en) | 6 | 384 | 37.8 | |
|
| [jina-reranker-v1-tiny-en](https://huggingface.co/jinaai/jina-reranker-v1-tiny-en) | 4 | 384 | 33.0 | |
|
|
|
> Currently, the `jina-reranker-v1-base-en` model is not available on Hugging Face. You can access it via the [Jina AI Reranker API](https://jina.ai/reranker/). |
|
|
|
As you can see, the `jina-reranker-v1-turbo-en` offers a balanced approach with **6 layers** and **37.8 million** parameters. This translates to fast search and reranking while preserving a high degree of accuracy. The `jina-reranker-v1-tiny-en` prioritizes speed even further, achieving the fastest inference speeds with its **4-layer**, **33.0 million** parameter architecture. This makes it ideal for scenarios where absolute top accuracy is less crucial. |

|
# Usage |
|
|
|
1. The easiest way to starting using `jina-reranker-v1-tiny-en` is to use Jina AI's [Reranker API](https://jina.ai/reranker/). |
|
|
|
```bash |
|
curl https://api.jina.ai/v1/rerank \ |
|
-H "Content-Type: application/json" \ |
|
-H "Authorization: Bearer YOUR_API_KEY" \ |
|
-d '{ |
|
"model": "jina-reranker-v1-tiny-en", |
|
"query": "Organic skincare products for sensitive skin", |
|
"documents": [ |
|
"Eco-friendly kitchenware for modern homes", |
|
"Biodegradable cleaning supplies for eco-conscious consumers", |
|
"Organic cotton baby clothes for sensitive skin", |
|
"Natural organic skincare range for sensitive skin", |
|
"Tech gadgets for smart homes: 2024 edition", |
|
"Sustainable gardening tools and compost solutions", |
|
"Sensitive skin-friendly facial cleansers and toners", |
|
"Organic food wraps and storage solutions", |
|
"All-natural pet food for dogs with allergies", |
|
"Yoga mats made from recycled materials" |
|
], |
|
"top_n": 3 |
|
}' |
|
``` |
|
|
|
2. Alternatively, you can use the latest version of the `sentence-transformers>=0.27.0` library. You can install it via pip: |
|
|
|
```bash |
|
pip install -U sentence-transformers |
|
``` |
|
|
|
Then, you can use the following code to interact with the model: |
|
|
|
```python |
|
from sentence_transformers import CrossEncoder |
|
|
|
# Load the model, here we use our tiny sized model |
|
model = CrossEncoder("jinaai/jina-reranker-v1-tiny-en", trust_remote_code=True) |
|
|
|
# Example query and documents |
|
query = "Organic skincare products for sensitive skin" |
|
documents = [ |
|
"Eco-friendly kitchenware for modern homes", |
|
"Biodegradable cleaning supplies for eco-conscious consumers", |
|
"Organic cotton baby clothes for sensitive skin", |
|
"Natural organic skincare range for sensitive skin", |
|
"Tech gadgets for smart homes: 2024 edition", |
|
"Sustainable gardening tools and compost solutions", |
|
"Sensitive skin-friendly facial cleansers and toners", |
|
"Organic food wraps and storage solutions", |
|
"All-natural pet food for dogs with allergies", |
|
"Yoga mats made from recycled materials" |
|
] |
|
|
|
results = model.rank(query, documents, return_documents=True, top_k=3) |
|
``` |
|
|
|
3. You can also use the `transformers` library to interact with the model programmatically. |
|
|
|
```python |
|
!pip install transformers |
|
from transformers import AutoModelForSequenceClassification |
|
|
|
model = AutoModelForSequenceClassification.from_pretrained( |
|
'jinaai/jina-reranker-v1-tiny-en', num_labels=1, trust_remote_code=True |
|
) |
|
|
|
# Example query and documents |
|
query = "Organic skincare products for sensitive skin" |
|
documents = [ |
|
"Eco-friendly kitchenware for modern homes", |
|
"Biodegradable cleaning supplies for eco-conscious consumers", |
|
"Organic cotton baby clothes for sensitive skin", |
|
"Natural organic skincare range for sensitive skin", |
|
"Tech gadgets for smart homes: 2024 edition", |
|
"Sustainable gardening tools and compost solutions", |
|
"Sensitive skin-friendly facial cleansers and toners", |
|
"Organic food wraps and storage solutions", |
|
"All-natural pet food for dogs with allergies", |
|
"Yoga mats made from recycled materials" |
|
] |
|
|
|
# construct sentence pairs |
|
sentence_pairs = [[query, doc] for doc in documents] |
|
|
|
scores = model.compute_score(sentence_pairs) |
|
``` |
|
|
|
That's it! You can now use the `jina-reranker-v1-tiny-en` model in your projects. |
|
|

# Evaluation |
|
|
|
We evaluated Jina Reranker on 3 key benchmarks to ensure top-tier performance and search relevance. |
|
|
|
| Model Name | NDCG@10 (17 BEIR datasets) | NDCG@10 (5 LoCo datasets) | Hit Rate (LlamaIndex RAG) | |
|
| ------------------------------------------ | -------------------------- | ------------------------- | ------------------------- | |
|
| `jina-reranker-v1-base-en` | **52.45** | **87.31** | **85.53** | |
|
| `jina-reranker-v1-turbo-en` | **49.60** | **69.21** | **85.13** | |
|
| `jina-reranker-v1-tiny-en` (you are here) | **48.54** | **70.29** | **85.00** | |
|
| `mxbai-rerank-base-v1` | 49.19 | - | 82.50 | |
|
| `mxbai-rerank-xsmall-v1` | 48.80 | - | 83.69 | |
|
| `ms-marco-MiniLM-L-6-v2` | 48.64 | - | 82.63 | |
|
| `ms-marco-MiniLM-L-4-v2` | 47.81 | - | 83.82 | |
|
| `bge-reranker-base` | 47.89 | - | 83.03 | |
|
|
|
**Note:** |
|
|
|
- `NDCG@10` is a measure of ranking quality, with higher scores indicating better search results. `Hit Rate` measures the percentage of relevant documents that appear in the top 10 search results. |
|
- The results of LoCo datasets on other models are not available since they **do not support** long documents more than 512 tokens. |
