# jina-embeddings-v5-text-small

`jina-embeddings-v5-text-small` is the fifth generation of Jina AI's multilingual embedding models, released on February 18, 2026. For a lighter alternative, see [jina-embeddings-v5-text-nano](https://huggingface.co/jinaai/jina-embeddings-v5-text-nano) (239M parameters).

[Elastic Inference Service](https://www.elastic.co/docs/explore-analyze/elastic-inference/eis) | [ArXiv](https://arxiv.org/abs/2602.15547) | [Release Note](https://jina.ai/news/jina-embeddings-v5-text-distilling-4b-quality-into-sub-1b-multilingual-embeddings) | [Blog](https://www.elastic.co/search-labs/blog/jina-embeddings-v5-text)

## Model Overview

<p align="center">
<img src="https://jina-ai-gmbh.ghost.io/content/images/2026/02/v5_architecture_1771470917.png" alt="jina-embeddings-v5-text Architecture" width="600px">
</p>

`jina-embeddings-v5-text-small` scores 71.7 average on MTEB English v2 and 67.7 on MMTEB with 677M parameters, the highest among multilingual embedding models under 1B parameters. Built on Qwen3-0.6B-Base and trained by combining embedding distillation from Qwen3-Embedding-4B with task-specific contrastive losses, it supports 119+ languages with up to 32K tokens and produces embeddings robust under truncation and binary quantization.

It is part of the **jina-embeddings-v5-text** model family, which also includes [jina-embeddings-v5-text-nano](https://huggingface.co/jinaai/jina-embeddings-v5-text-nano), a smaller model for resource-constrained use cases.

## Training and Evaluation

For training details and evaluation results, see our [technical report](https://arxiv.org/abs/2602.15547).

## Usage

<details>
  <summary>Requirements</a></summary>
  
The following Python packages are required:

- `transformers>=4.57.0`
- `torch>=2.8.0`
- `peft>=0.15.2`
  
### Optional / Recommended
- **flash-attention**: Installing [flash-attention](https://github.com/Dao-AILab/flash-attention) is recommended for improved inference speed and efficiency, but not mandatory.
- **sentence-transformers**: If you want to use the model via the `sentence-transformers` interface, install this package as well.

The fastest way to use v5-text in production. Elastic Inference Service (EIS) provides managed embedding inference with built-in scaling, so you can generate embeddings directly within your Elastic deployment.

```bash
PUT _inference/text_embedding/jina-v5
{
  "service": "elastic",
  "service_settings": {
    "model_id": "jina-embeddings-v5-text-small"
  }
}
```

See the [Elastic Inference Service documentation](https://www.elastic.co/docs/explore-analyze/elastic-inference/eis) for setup details.

We provide separate model versions for each task (`retrieval`, `text-matching`, `classification`, `clustering`).
For each model, the task-specific adapter is merged into the base model weights.  
This modification enables simpler compatibility with vLLM.

Instructions and usage examples for each task are available in their respective model repositories:
