Jina is an open-source deep-learning powered search framework, empowering developers to create cross-modal or multi-modal search systems for text, images, video, and audio. Jina is a cloud-native project, and provides long-term support from a full-time, venture-backed team.

⏱️ Time Saver - Bootstrap an AI-powered system in just a few minutes with cookiecutter.

🧠 First-Class AI models - Jina is a new design pattern for neural search systems with first-class support for state-of-the-art AI models like Faiss, Annoy, Onnx, and more.

🌌 Universal Search - Large-scale indexing and querying data of any kind on multiple platforms. Video, image, long/short text, music, source code, and more.

🚀 Production Ready - Cloud-native features out-of-the-box, like containerization, microservice, distributing, scaling, sharding, async IO, REST, gRPC.

🧩 Plug & Play - With Jina Hub, you can extend Jina with simple Python scripts or Docker images optimized for your search domain.

Get Started

From PyPi

On Linux/MacOS with Python >= 3.7:

pip install jina

To install Jina with extra dependencies, or install on Raspberry Pi please refer to the documentation.

With Cookiecutter

pip install cookiecutter && cookiecutter gh:jina-ai/cookiecutter-jina

With Cookiecutter you can easily create a Jina project from templates with one terminal command. This creates a Python entrypoint, YAML configs and a Dockerfile. You can start from there.

In a Docker Container

We provide a universal Docker image that supports multiple architectures (including x64, x86, arm-64/v7/v6). Simply run:

docker run jinaai/jina --help

Jina "Hello, World!" 👋🌍

As a starter, you can try out our "Hello, World" - a simple demo of image neural search for Fashion-MNIST. No extra dependencies needed, just run:

jina hello-world

...or even easier for Docker users, no install required:

docker run -v "$(pwd)/j:/j" jinaai/jina hello-world --workdir /j && open j/hello-world.html  # replace "open" with "xdg-open" on Linux

Click here to see console output

The Docker image downloads the Fashion-MNIST training and test dataset and tells Jina to index 60,000 images from the training set. Then it randomly samples images from the test set as queries and asks Jina to retrieve relevant results. The whole process takes about 1 minute, and eventually opens a webpage and shows results like this:

The implementation behind it is simple:

Python API

or use YAML spec

or use Dashboard

from jina.flow import Flow

f = (Flow()
        .add(uses='encoder.yml', parallel=2)
        .add(uses='indexer.yml', shards=2, 
             separated_workspace=True))

with f:
    f.index(fashion_mnist, batch_size=1024)

!Flow
pods:
  encode:
    uses: encoder.yml
    parallel: 2
  index:
    uses: indexer.yml
    shards: 2
    separated_workspace: true

Explore sharding, containerization, concatenating embeddings, and more

Adding Parallelism and Sharding

from jina.flow import Flow

f = (Flow().add(uses='encoder.yml', parallel=2)
           .add(uses='indexer.yml', shards=2, separated_workspace=True))

Distributing the Flow

from jina.flow import Flow

f = Flow().add(uses='encoder.yml', host='192.168.0.99')

Using a Docker Container

from jina.flow import Flow

f = (Flow().add(uses='jinahub/cnn-encode:0.1')
           .add(uses='jinahub/faiss-index:0.2', host='192.168.0.99'))

Concatenating Embeddings

from jina.flow import Flow

f = (Flow().add(name='eb1', uses='BiTImageEncoder')
           .add(name='eb2', uses='KerasImageEncoder', needs='gateway')
           .needs(['eb1', 'eb2'], uses='_concat'))

Enabling Network Queries

from jina.flow import Flow

f = Flow(port_expose=45678, rest_api=True)

with f:
    f.block()
