About Serve
Jina is an open-source framework for building multimodal AI services and pipelines that communicate via gRPC, HTTP, and WebSockets. It allows developers to focus on logic and algorithms while handling infrastructure complexity, scaling from local deployment to advanced orchestration with Docker Compose, Kubernetes, or Jina AI Cloud. Jina supports any data type, any mainstream deep learning framework, and features dynamic batching, streaming, async processing, and observability via OpenTelemetry/Prometheus. It also provides Docker container integration through Executor Hub and streamlined CPU/GPU hosting.

FAQ
How is Jina different from FastAPI?
FastAPI relies on Pydantic for data structures, while Jina uses DocArray, allowing Jina to support multiple protocols including gRPC for more efficient serialization of tensors and embeddings. Jina also provides advanced orchestration and scaling capabilities, enabling easy containerization and deployment to Kubernetes, Docker Compose, or Jina AI Cloud.
