jina-embeddings-v3 Overview
The jina-embeddings-v3 model is JinaAI's newly released multilingual text embedding tool with 570 million parameters and a maximum input length of 8192 tokens. It can handle multilingual data processing and long-context retrieval tasks, achieving state-of-the-art (SOTA) performance across 94 languages. This model creates embeddings suited for a range of tasks, including query-document retrieval, clustering, classification, and text matching.
Jina-embeddings-v3 also supports Matryoshka Embeddings, which lets you customize the output embedding size based on your needs. While the default output dimension is 1024, you can reduce it to 32, 64, 128, 256, 512, or 768 without losing too much performance, making it adaptable for various applications.

| jina-embeddings-v2-base-code | 161M | 768 | English and programming languages |
How to create embeddings with jina-embeddings-v3
There are two primary ways to generate vector embeddings:
- PyMilvus: the Python SDK for Milvus that seamlessly integrates the
jina-embeddings-v3model. - SentenceTransformer library: the Python library
sentence-transformer.
Once the vector embeddings are generated, they can be stored in Zilliz Cloud (a fully managed vector database service powered by Milvus) and used for semantic similarity search. Here are four key steps:
- Sign up for a Zilliz Cloud account for free.
- Set up a serverless cluster and obtain the Public Endpoint and API Key.
- Create a vector collection and insert your vector embeddings.
- Run a semantic search on the stored embeddings.
