Argilla is an open-source data annotation and curation platform designed for AI engineers and domain experts building high-quality datasets for LLMs and NLP models. The platform provides a FastAPI-based REST API for managing workspaces, datasets, records, responses, suggestions, and vectors, enabling RLHF and preference tuning pipelines. Developers interact with Argilla through a Python SDK (pip install argilla) or directly via REST using API key authentication. Argilla supports deployment on Hugging Face Spaces, Docker, and self-hosted environments, and is licensed under Apache-2.0. The platform recently joined Hugging Face, deepening its integration with the broader open ML ecosystem.
