Argilla
Data curation — human-in-the-loop for LLM training data
📋 Overview
Argilla is an open-source data curation platform for human-in-the-loop creation of LLM training data. Unlike Label Studio (which is general-purpose), Argilla is purpose-built for LLM data — supporting preference ranking, RLHF annotation, and quality control for instruction datasets. It provides a comprehensive solution for modern AI workflows.
