## Intented Usage & Model Info |
|
|
|
`jina-embedding-t-en-v1` is a language model that has been trained using Jina AI's Linnaeus-Clean dataset. |
|
This dataset consists of 380 million pairs of sentences, which include both query-document pairs. |
|
These pairs were obtained from various domains and were carefully selected through a thorough cleaning process. |
|
The Linnaeus-Full dataset, from which the Linnaeus-Clean dataset is derived, originally contained 1.6 billion sentence pairs. |
|
|
|
The model has a range of use cases, including information retrieval, semantic textual similarity, text reranking, and more. |
|
|
|
With a compact size of just 14 million parameters, |
|
the model enables lightning-fast inference while still delivering impressive performance. |
|
Additionally, we provide the following options: |
|
|
|
- `jina-embedding-t-en-v1`: 14 million parameters **(you are here)**. |
|
- `jina-embedding-s-en-v1`: 35 million parameters. |
|
- `jina-embedding-b-en-v1`: 110 million parameters. |
|
- `jina-embedding-l-en-v1`: 330 million parameters. |
|
- `jina-embedding-1b-en-v1`: 1.2 billion parameters, 10* bert-base size (soon). |
|
- `jina-embedding-6b-en-v1`: 6 billion parameters 30* bert-base size(soon). |
|
|
|
## Data & Parameters |

|
## Usage |
|
|
|
Use with Jina AI Finetuner |
|
|
|
```python |
|
!pip install finetuner |
|
import finetuner |
|
|
|
model = finetuner.build_model('jinaai/jina-embedding-t-en-v1') |
|
embeddings = finetuner.encode( |
|
model=model, |
|
data=['how is the weather today', 'What is the current weather like today?'] |
|
) |
|
print(finetuner.cos_sim(embeddings[0], embeddings[1])) |
|
``` |
|
|
|
Use directly with sentence-transformers: |
|
|
|
```python |
|
from sentence_transformers import SentenceTransformer |
|
from sentence_transformers.util import cos_sim |
|
|
|
sentences = ['how is the weather today', 'What is the current weather like today?'] |
|
|
|
model = SentenceTransformer('jinaai/jina-embedding-t-en-v1') |
|
embeddings = model.encode(sentences) |
|
print(cos_sim(embeddings[0], embeddings[1])) |
|
``` |
|
|
|
## Fine-tuning |
|
|
|
Please consider [Finetuner](https://github.com/jina-ai/finetuner). |
|
|
|
## Plans |
|
|
|
1. The development of `jina-embedding-s-en-v2` is currently underway with two main objectives: improving performance and increasing the maximum sequence length. |
|
2. We are currently working on a bilingual embedding model that combines English and X language. The upcoming model will be called `jina-embedding-s/b/l-de-v1`. |
