Welcome to Jina!#

Jina is a MLOps framework that empowers anyone to build cross-modal and multi-modal applications on the cloud. It uplifts a PoC into a production-ready service. Jina handles the infrastructure complexity, making advanced solution engineering and cloud-native technologies accessible to every developer.

Applications built with Jina enjoy the following features out of the box:

🌌 Universal

Build applications that deliver fresh insights from multiple data types such as text, image, audio, video, 3D mesh, PDF with Jina AI’s DocArray.
Support all mainstream deep learning frameworks.
Polyglot gateway that supports gRPC, Websockets, HTTP, GraphQL protocols with TLS.

⚡ Performance

Intuitive design pattern for high-performance microservices.
Scaling at ease: set replicas, sharding in one line.
Duplex streaming between client and server.
Async and non-blocking data processing over dynamic flows.

☁️ Cloud-native

Seamless Docker container integration: sharing, exploring, sandboxing, versioning and dependency control via Executor Hub.
Full observability via Prometheus and Grafana.
Fast deployment to Kubernetes, Docker Compose.

🍱 Ecosystem

Improved engineering efficiency thanks to the Jina AI ecosystem, so you can focus on innovating with the data applications you build.
Free CPU/GPU hosting via Jina Cloud.

Install#

Make sure that you have Python 3.7+ installed on Linux/MacOS/Windows.

via PyPI

pip install -U jina

via Conda

conda install jina -c conda-forge

via Docker

docker pull jinaai/jina:latest

Now that you’re set up, let’s create a project:

In host

jina new hello-jina
cd hello-jina
jina flow --uses flow.yml

Inside Docker

docker run -it --entrypoint=/bin/bash jinaai/jina:latest -p 54321:54321
jina new hello-jina
cd hello-jina
jina flow --uses flow.yml

Run the client on your machine and observe the results from your terminal.

python client.py
['hello, world!', 'goodbye, world!']

Next steps#

Learn DocArray API

DocArray is the foundational data structure of Jina. Before starting Jina, first learn DocArray to quickly build a PoC.

Understand Executor

Executor is a self-contained logic unit that performs a group of tasks on a DocumentArray.

Understand Flow

Flow orchestrates Executors into a processing pipeline to build a multi-modal/cross-modal application

Explore Executor Hub

Executor Hub is an Executor marketplace that allows you to share, explore and test Executors.

Deploy a Flow to JCloud

JCloud is a free CPU/GPU hosting platform for Jina projects.
