ai4j

About

Java teams who want agentic behavior historically had to bridge to Python ecosystems; ai4j provides the equivalent natively for JDK 8+, including Spring Boot starters and a BOM. The SDK normalizes OpenAI-compatible, Anthropic, DashScope, Doubao, DeepSeek, Moonshot, Ollama, and other wire formats behind one API, layers tool calling, RAG (Pinecone, Qdrant, pgvector, Milvus, Redis), and AgentFlow integration with Dify, Coze, and n8n on top, and ships a coding agent surface installable via Maven (io.github.lnyo-cly:ai4j). It is a single-maintainer project with 949 commits, an active changelog, and GitHub Pages documentation, at version 2.4.2.
