autogen4j is a lightweight Java library designed to abstract the complexity of building autonomous AI agents. It offers core modules for planning, memory storage, and action execution, letting agents decompose high-level goals into sequential sub-tasks. The framework integrates with LLM providers (e.g., OpenAI, Anthropic) and allows registration of custom tools (HTTP clients, database connectors, file I/O). Developers define agents through a fluent DSL or annotations, quickly assembling pipelines for data enrichment, automated reporting, and conversational bots. An extensible plugin system ensures flexibility, enabling fine-tuned behaviors across diverse applications.
