OxyJen

OxyJen is an open-source Java framework for orchestrating LLM workloads with graph-style execution, context-aware memory, and deterministic retry/fallback. It treats LLMs as native nodes (not helper utilities), allowing developers to build multi-step AI pipelines that integrate cleanly with existing Java code. Maintained by 11divyansh on GitHub, where it has earned 38 stars from the community.

It's actively developed around agents, ai, chatgpt, and is a solid reference for anyone building with these tools.
