Agents-Flex is a lightweight, modular Java framework for building AI applications and agents, positioned as a Java counterpart to Spring AI. It provides unified abstractions for chat models, tool calling, durable agent runtimes, RAG pipelines, MCP, Skills with sandboxed execution, multimodal models (image, TTS, STT, video, OCR), Text2SQL, and OpenTelemetry observability.

Use cases

• build ai agents in java
• add llm chat to a spring boot app
• build a rag knowledge base chatbot
• connect multiple llm providers with one api
• tool calling and function calling in java
• streaming chat responses in a web app
• extract text from pdfs and office docs with ocr
• run durable long-running ai tasks that survive restarts

When to choose

• you are a Java/JVM developer building LLM-powered applications or agents
• you want a Spring AI or LangChain4j alternative that works without Spring
• you need production features like retries, load balancing, circuit breaking, and observability out of the box
• you need durable, recoverable agent runs and async task tracking across restarts
• you want RAG, MCP, Skills, and multimodal capabilities in one modular framework

When to avoid

• your stack is Python, JavaScript, or another non-JVM language
• you only need a simple one-off script calling an LLM API
• you need a ready-made end-user chat application rather than a development framework
• you are locked to JDK 8 but need the MCP module, which requires JDK 17+
