How to Use AI in Java
In 2026, Java is no longer just for enterprise backends; it is a powerhouse for production-grade AI. Whether you are building Generative AI agents or Machine Learning models, here is the modern roadmap.
1. Integrating LLMs with Spring AI
The most popular way to use AI in Java today is via Spring AI. It provides a unified interface to interact with models like OpenAI, Google Gemini, and Anthropic.
String response = chatClient.prompt()
.user("Analyze this Java code for security flaws")
.call().content();
Use case: Chatbots, RAG (Retrieval Augmented Generation), and AI Agents.
2. JVM-Native Machine Learning
If you need to run models directly on the JVM for performance or security, use Deep Java Library (DJL) or Tribuo.
- DJL: High-level engine that supports PyTorch/TensorFlow models in Java.
- Tribuo: Focuses on type-safety and model provenance—ideal for enterprise ML.
3. AI-Powered Development Workflow
Beyond the code you write, use AI to write the code. 2026 tools have evolved to understand complex Spring Boot architectures.
Top Java AI Libraries (2026)
| Library | Specialty | Status |
|---|---|---|
| Spring AI | LLM Orchestration & RAG | Industry Standard |
| LangChain4j | Declarative AI Services | High Growth |
| DJL | Native Deep Learning | Performance-Heavy |
| Deeplearning4j | JVM-native DL Training | Legacy/Specialized |
