About distilabel

Distilabel is an open-source framework for building pipelines that generate synthetic data and collect AI feedback based on research methods. It covers predictive NLP tasks such as classification and extraction, as well as language-model tasks such as instruction following, dialogue generation, and judging, and provides a unified API for getting feedback from different LLM providers.

It installs with pip and requires Python 3.9+. Optional extras add support for specific providers and for exporting datasets to Argilla. The original authors have moved on to other projects, and community collaborators are maintaining the project, with current fixes available on the develop branch.
