Argilla is an open-source data annotation and dataset-building framework tailored for NLP and LLM workflows. It provides a Python SDK (with an intuitive API) and a web-based UI that integrates with popular ML libraries, supporting pipelines for RLHF, supervised fine-tuning (SFT), and model evaluation. Its companion library, Distilabel, enables AI-assisted data generation and labeling at scale. Argilla can be self-hosted or run via the cloud, and its tight integration with the Hugging Face ecosystem makes it straightforward to push curated datasets directly to the Hub.
