Human In The Loop Workflows With Feedback Collection And Model Improvement

via “human-in-the-loop workflows with explicit approval gates”

Open-source AI orchestration framework for building context-engineered, production-ready LLM applications. Design modular pipelines and agent workflows with explicit control over retrieval, routing, memory, and generation. Built for scalable agents, RAG, multimodal applications, semantic search, and

Unique: Implements HITL as explicit pipeline components that pause execution and wait for human input. Supports both synchronous blocking and asynchronous non-blocking patterns, with state persistence across interactions.

vs others: More flexible than LangChain's human-in-the-loop because it's a first-class pipeline component; more explicit than AutoGPT's approval patterns because the approval logic is visible in the pipeline DAG.
