About

What jina-reranker-en is

This model is designed for blazing-fast reranking while maintaining competitive performance. What's more, it leverages the power of our JinaBERT model as its foundation. JinaBERT itself is a unique variant of the BERT architecture that supports the symmetric bidirectional variant of ALiBi. This allows jina-reranker-v1-turbo-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-turbo-en employ a technique called knowledge distillation. Here, a complex, but slower, model (like our original jina-reranker-v1-base-en) 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 NameLayersHidden SizeParameters (Millions)
jina-reranker-v1-base-en12768137.0
jina-reranker-v1-turbo-en638437.8
jina-reranker-v1-tiny-en438433.0

Currently, the jina-reranker-v1-base-en model is not available on Hugging Face. You can access it via the Jina AI Reranker API.

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-turbo-en is to use Jina AI's Reranker API.
curl https://api.jina.ai/v1/rerank \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{
  "model": "jina-reranker-v1-turbo-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
}'
  1. Alternatively, you can use the latest version of the sentence-transformers>=0.27.0 library. You can install it via pip:
pip install -U sentence-transformers

Then, you can use the following code to interact with the model:

from sentence_transformers import CrossEncoder

# Load the model, here we use our turbo sized model
model = CrossEncoder("jinaai/jina-reranker-v1-turbo-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)
  1. You can also use the transformers library to interact with the model programmatically.
!pip install transformers
from transformers import AutoModelForSequenceClassification

model = AutoModelForSequenceClassification.from_pretrained(
    'jinaai/jina-reranker-v1-turbo-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)
  1. You can also use the transformers.js library to run the model directly in JavaScript (in-browser, Node.js, Deno, etc.)!

If you haven't already, you can install the Transformers.js JavaScript library from NPM using:

npm i @xenova/transformers

Then, you can use the following code to interact with the model:

import { AutoTokenizer, AutoModelForS

Using it via the API

Call it like any OpenAI endpoint

Once AxForge deploys jina-reranker-en for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (jina-reranker-en below is illustrative; you get the exact model name on deployment.)

$ curl -sS https://api.axforge.ai/v1/embeddings \
  -H "Authorization: Bearer $AXFORGE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"jina-reranker-en","input":"text to embed"}'
