Deep Java Library (DJL) is an engine-agnostic, high-level deep learning framework for Java that supports backends like PyTorch, TensorFlow, MXNet, and ONNX Runtime. It lets Java developers build, train, and deploy deep learning models with a native Java API, including a pre-trained model zoo and automatic CPU/GPU selection.

Use cases

• run deep learning inference in a Java application
• train neural networks from Java without writing Python
• load pre-trained models from a model zoo for object detection
• switch deep learning engines without changing application code
• serve ML models inside existing JVM microservices
• use GPU acceleration for Java-based ML workloads

When to choose

• your team is Java/JVM-based and wants to avoid a Python stack
• you need engine-agnostic model loading and inference in production Java services
• you want pre-trained models with a simple Criteria-based API

When to avoid

• you need cutting-edge research models or rapid Python-ecosystem experimentation
• your project is non-JVM and a native Python framework fits directly
• you need fine-grained low-level control over a specific engine's internals
